Product details
Overview
5KP110AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 177 V maximum clamping voltage at 28.2 A, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs and ICs in automotive power supplies against lightning-induced transients.
For engineers reviewing the 5KP110AHE3/54 datasheet, 5KP110AHE3/54 pinout, 5KP110AHE3/54 application, or 5KP110AHE3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS, peak pulse current handling under 10/1000 μs waveform, AEC-Q101 qualification status, thermal derating above 25 °C, and P600 package mounting requirements for sustained surge dissipation.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables DC-biased rail protection without reverse conduction during normal operation.
The device delivers 5000 W peak pulse power with strict 0.01 % duty cycle limitation and is rated for 500 A non-repetitive forward surge current (8.3 ms half-sine). It meets AEC-Q101 stress test requirements and supports soldering up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum overvoltage threshold for protection activation. |
| VBR (min/max) | 122 V / 135 V at 5 mA - Confirmed breakdown range ensures predictable turn-on within design margin above VWM. |
| VC @ IPPM | 177 V at 28.2 A - Clamping voltage under full-rated 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM | 5000 W - Peak pulse power rating defines energy-handling capability for transient suppression without failure. |
| TJ max. | +175 °C - Maximum junction temperature enables use in under-hood automotive environments and high-ambient industrial settings. |
| IFSM | 500 A - Non-repetitive forward surge current rating supports crowbar-style fault clearing in power supply outputs. |
| Polarity | Unidirectional - Allows placement on positive-rail-only protection paths; cathode marked by color band. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 compliant; 0.375" (9.5 mm) body length; lead diameter 0.048–0.052" (1.22–1.32 mm); intended for through-hole mounting with heatsinking via PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., ground or return path); conducts during positive transients when cathode is biased higher. |
| Cathode | Clamping terminal | Marked by color band; connected to protected line (e.g., +12 V rail); initiates avalanche breakdown when voltage exceeds VBR, shunting surge current to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per JEDEC standards. |
| P600 glass passivated junction | Enables stable VBR tolerance and low leakage (<2 μA at VWM) across temperature and lifetime. |
| 5000 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without degradation when properly mounted. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving clamping fidelity. |
| Solderable per J-STD-002/JESD 22-B102 | Ensures robust lead wetting and intermetallic formation during wave or hand soldering processes. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|

Use Value: 175 °C max junction temperature and 500 A IFSM rating allow survival of repeated motor stall events without parametric shift. |
Use Scenario: Protecting LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in engine control modules. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on signal lines referenced to chassis ground, minimizing signal distortion. Use Value: Confirmed <2 μA leakage at 110 V ensures no DC loading on high-impedance sensor bias networks or LIN pull-up resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, AEC-Q101 qualified. | Targeted for space-constrained PCBs with lower surge exposure (e.g., infotainment USB ports). | Select when board area is limited and peak surge energy does not exceed 600 W; verify thermal relief for repeated events. |
| 1.5KE110A | Same VWM/VBR, 1500 W PPPM, DO-201 package, not AEC-Q101 qualified. | Suitable for commercial/industrial power supplies where automotive qualification is not required. | Choose for cost-sensitive non-automotive designs where 1500 W surge capacity suffices and qualification is optional. |
Compared with SMBJ110AHE3/52 and 1.5KE110A, the 5KP110AHE3/54 provides three-fold higher peak pulse power and automotive-grade reliability in a thermally robust P600 package-making it the only option among the three capable of sustaining repeated 5000 W transients in under-hood environments.

FAQ
What is the clamping voltage of the 5KP110AHE3/54 under full-rated surge current?
The 5KP110AHE3/54 has a maximum clamping voltage (VC) of 177 V when subjected to its rated peak pulse current of 28.2 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 5KP110AHE3/54 qualified for automotive applications?
Yes, the 5KP110AHE3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and electrostatic discharge per JEDEC standards. The HE3 suffix explicitly denotes AEC-Q101 compliance.
What package type does the 5KP110AHE3/54 use, and what are its key mechanical features?
The 5KP110AHE3/54 uses the P600 package: a molded epoxy body with glass-passivated chip junction, UL 94 V-0 flammability rating, 0.375" (9.5 mm) body length, and matte tin-plated leads. It supports soldering up to 275 °C for 10 s and is designed for through-hole mounting with thermal relief via PCB copper area.
How does the 5KP110AHE3/54 differ from the 5KP110A-E3/54 variant?
The 5KP110AHE3/54 includes the HE3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the 5KP110A-E3/54 carries only the E3 suffix denoting RoHS compliance and JESD 201 Class 1A whisker resistance-without automotive qualification.
What is the maximum operating temperature range for the 5KP110AHE3/54?
The 5KP110AHE3/54 has an operating junction and storage temperature range of –55 °C to +175 °C. This wide range supports deployment in under-hood automotive locations, industrial motor controls, and outdoor power infrastructure where ambient temperatures exceed 125 °C.
