Product details
Overview
5KP54AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 54 V stand-off voltage (VWM), 60.0–66.3 V breakdown voltage (VBR) at 5 mA, 87.1 V maximum clamping voltage (VC) at 57.4 A peak pulse current, and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs against lightning-induced transients in automotive power supplies.
For engineers reviewing the 5KP54AHE3_A/C datasheet, 5KP54AHE3_A/C pinout, 5KP54AHE3_A/C application, or 5KP54AHE3_A/C equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity requirement, P600 thermal derating above 25 °C, AEC-Q101 qualification status, and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for low incremental surge resistance and sub-nanosecond response time. Its unidirectional structure provides forward conduction only during overvoltage events, enabling crowbar-like protection without reverse leakage interference in DC-biased circuits.
The device operates within -55 °C to +175 °C junction temperature range and sustains 500 A non-repetitive forward surge current (8.3 ms half-sine). Thermal performance is governed by lead temperature (TL) derating - power dissipation drops from 8.0 W at TL = 75 °C to zero at TL = 175 °C per Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin. |
| VBR (min/max) | 60.0 V / 66.3 V at 5 mA - Confirmed breakdown threshold range; ensures reliable turn-on before protected IC exceeds its 65 V abs max rating. |
| VC @ IPPM | 87.1 V at 57.4 A - Clamped voltage under 10/1000 μs surge; defines worst-case stress on downstream components. |
| PPPM | 5000 W - Peak pulse power handling (10/1000 μs); supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge testing. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with minimal heatsinking. |
| Polarity | Unidirectional - Cathode marked by band; suitable for DC-biased rails where reverse conduction must be blocked. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ54A | Same VWM (54 V), lower PPPM (400 W), DO-214AC package, 1000 W peak pulse rating | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements. |

FAQ
What is the clamping voltage of the 5KP54AHE3_A/C under a 10/1000 μs surge?
The 5KP54AHE3_A/C exhibits a maximum clamping voltage (VC) of 87.1 V when subjected to its rated peak pulse current of 57.4 A using the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The 5KP54AHE3_A/C maintains this clamping performance across its full operating temperature range.
Is the 5KP54AHE3_A/C suitable for automotive applications?
Yes, the 5KP54AHE3_A/C is explicitly AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per automotive reliability standards. Its P600 package, 175 °C maximum junction temperature, and unidirectional polarity make it appropriate for under-hood power rail protection in ECUs, BMS, and ADAS modules. The 5KP54AHE3_A/C meets the thermal and surge immunity requirements of ISO 7637-2 and ISO 16750-2.
How does the 5KP54AHE3_A/C differ from the standard 5KP54A-E3 variant?
The 5KP54AHE3_A/C differs from the commercial-grade 5KP54A-E3 by its AEC-Q101 qualification (denoted by "H" in HE3), enhanced whisker resistance (JESD 201 Class 2), and packaging in 13" paper tape and reel with C-code carrier (vs. 54-code for E3). Both share identical electrical parameters and P600 mechanical form factor, but only the 5KP54AHE3_A/C is approved for automotive production use. The 5KP54AHE3_A/C data sheet specifies the same VWM, VBR, and VC values as the base 5KP54A family.
What is the maximum operating temperature for the 5KP54AHE3_A/C?
The 5KP54AHE3_A/C has a specified operating junction temperature range of -55 °C to +175 °C. Its thermal design allows sustained operation at 175 °C when mounted on an adequate heatsink and operated within derated power limits per Figure 5 of the datasheet. At ambient temperatures exceeding 100 °C, PCB copper area and thermal vias become critical to maintain safe junction temperatures. The 5KP54AHE3_A/C's P600 package contributes significant thermal mass to buffer transient heating.
Can the 5KP54AHE3_A/C replace a crowbar circuit in power supplies?
Yes, the 5KP54AHE3_A/C was explicitly designed to replace traditional crowbar circuits (SCR + fuse) in switching power supplies, as noted in Vishay's Application Notes. Its 5000 W peak pulse capability and low clamping ratio allow it to absorb surge energy while holding voltage below protected device limits, enabling circuit breakers or fuses to clear faults without device destruction. Unlike crowbars, the 5KP54AHE3_A/C resets automatically after transient clearance, supporting uninterrupted operation post-event.
