TE Connectivity PolySwitch Analogue Radial Leaded PTC Resettable Fuse TRF012 250V 0.12A

 

 

Introduction

 

Overcurrent protection is a most basic necessity for electrical devices. However, many people are familiar with fuses and household circuit breakers, but few of them are intimately familiar with the kinds of overcurrent protection devices-Ao littel PTC Resettable Fuse that are found in electronics board. Though not a comprehensive list, there are basically three types of overcurrent protection devices in electronics. In order of increasing sophistication they are:

• One-shot fuses (One-time fuse, normally called SMD Fuse,Glass Fuse,Ceramic Fuse,Subminiature fuse)

• Positive Temperature Coefficient PTC resettable fuses

• Electronic fuses (eFuses)

Comparison of technologies

 

One shot fuses(One-time fuse, normally called SMD Fuse,Glass Fuse,Ceramic Fuse,Subminiature fuse,thermal fuse etc.), which are based on melting of a metal link, must be replaced after a single high current event. They are commonly seen in applications like LED bulbs where a simple device makes sense. For LED bulbs the solution to a blown fuse is just to purchase another bulb. It is a small expense and the fault leading to the open fuse likely requires replacement of the bulb anyway. PTC resettable fuses are a step-up from one shot fuses. When a short circuit occurs, they heat up and transition from a low resistance state to a high resistance state. Allowing them to cool down (typically by removing the power) resets them to the low resistance state.

 

Resettable PTC fuse come in both ceramic (CPTC) and polymer (PPTC) types. Ceramic types are used in sensitive application spaces such as telecom where the resistance must not change much after tripping. The polymer type is used in many general electronics applications and is sometimes called alternatively a resettable fuse, or polyswitch. , here,a polymer type is compared against an eFuse. eFuses utilize a completely different operating principle than one-shot or PTC fuses. Instead of limiting current based entirely on heating, eFuses actually measure the current and turn off an internal switch if the current exceeds a specified limit.

 

Also, since eFuses are semiconductor integrated circuit devices they have a rapid (typically less than 10 s) response to short circuits as well as a plethora of features that may be included:

 

• Ability to operate over temperature with minimal shift in parameters

• No degradation after a fault; the on resistance does not depend on how many faults have occurred

• Programmable current limit

• Enable pin, to turn on or off the device

• Fault pin, to signal that something has gone wrong to control logic or other power rails

• Soft-start, to limit inrush current

•Voltage clamp, to prevent voltage spikes from reaching the load

• Choice of latch-off or auto-retry, so that everything will reset if the load recovers, but without needing to turn off the power

• Reverse current blocking

 

However, the eFuse arguably also has a few disadvantages such as having more terminals and requiring bias current to operate.

 

At the most basic level, an eFuse requires at least three terminals due to its architecture. These are input, output, and ground. In some cases it would be better to have a two-terminal device to make layout routing easier. For example, there is no need to connect a PTC to the ground plane.

 

Also, since the PTC resettable fuse does not require a ground pin, current only flows from input to output. This means that no bias current is required at all. This is an obvious advantage for battery-powered applications. However, the latest eFuses have reduced bias current considerably. For example, when the NIS5452 is turned off, its bias current is less than 100 A. Its predecessor, the NIS5135 has a bias current about 10 times higher. While it is true that the eFuse is more complicated due to its semiconductor architecture, advances in semiconductor technology have significantly reduced the size, and therefore expense, of eFuses. For example, one of the first eFuses from ON Semiconductor is the NIS5112 with 30 m RDS(on) in the SOIC−8 (5 × 4 × 1.75 mm) package. By contrast the upcoming NIS5020 is in a much smaller (3 × 3 × 1.0 mm) DFN10 package and has half the RDS(on).TE Connectivity PolySwitch Analogue Radial Leaded PTC Resettable Fuse TRF012 250V 0.12A
