Product details
Overview
5KP5.0HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 5.0 V stand-off voltage (VWM), 6.4–7.0 V breakdown (VBR), and 5000 W peak pulse power (10/1000 μs). It provides robust overvoltage protection for DC power rails in automotive ECUs and industrial motor drives where fast clamping and AEC-Q101 qualification are required.
For engineers reviewing the 5KP5.0HE3/54 datasheet, 5KP5.0HE3/54 pinout, 5KP5.0HE3/54 application, or 5KP5.0HE3/54 equivalent, key selection criteria include its 9.2 V maximum clamping voltage at 543 A peak pulse current, ±5% VBR tolerance, 2000 μA max reverse leakage at 5.0 V, and AEC-Q101 qualification for automotive-grade reliability under thermal cycling and surge stress.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for high-energy transients. Its unidirectional polarity enables integration into DC-biased circuits without forward conduction during normal operation, while the low incremental surge resistance ensures minimal voltage overshoot during 10/1000 μs surges up to 543 A.
The device operates across –55 °C to +175 °C junction temperature range and features a 0.057 %/°C VBR temperature coefficient. Its 3.5 V forward voltage at 100 A supports crowbar-like fault handling in power supply outputs, and it meets JESD 201 Class 2 whisker resistance with matte tin-plated leads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3/52 | Lower 600 W peak power, SMC package, same VWM/VBR, higher VC (9.6 V) | Suitable for space-constrained PCBs but insufficient for ISO 7637-2 Pulse 5a (5000 W) | Select when board area is critical and surge energy is ≤600 W |
| 1.5KE5.0A | Same P600 package, 1500 W rating, lower cost, non-AEC-Q101, higher VC (10.5 V) | Acceptable for commercial-grade power supplies without automotive qualification requirements | Select for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with SMBJ5.0AHE3/52 and 1.5KE5.0A, the 5KP5.0HE3/54 delivers 3.3× higher surge energy handling and automotive-grade reliability-critical when protecting safety-critical 5 V domains where failure modes must be bounded per ISO 26262 ASIL-B.

FAQ
What is the clamping voltage of the 5KP5.0HE3/54 under maximum rated surge conditions?
The 5KP5.0HE3/54 exhibits a maximum clamping voltage (VC) of 9.2 V when subjected to its rated 543 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures protected circuitry remains within safe voltage margins during worst-case transients. The 5KP5.0HE3/54 maintains this clamping performance across its full operating temperature range.
Is the 5KP5.0HE3/54 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KP5.0HE3/54 is explicitly AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number: 88308, Revision: 20-Nov-12). Its qualification covers thermal cycling, humidity bias, and surge endurance tests required for under-hood and powertrain applications. The 5KP5.0HE3/54 meets all stress test requirements defined in AEC-Q101, making it appropriate for use in engine control units and ADAS power supplies.
How does the 5KP5.0HE3/54 differ from the 5KP5.0A-E3/54 variant?
The 5KP5.0HE3/54 differs from the 5KP5.0A-E3/54 solely in qualification level: the "HE3" suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas "E3" indicates commercial-grade RoHS compliance only. Both share identical electrical characteristics (VWM, VBR, VC, IPPM) and P600 packaging. The 5KP5.0HE3/54 is intended for automotive and high-reliability industrial use, while the E3 version targets cost-sensitive commercial designs.
What is the maximum reverse leakage current of the 5KP5.0HE3/54 at its stand-off voltage?
The 5KP5.0HE3/54 has a maximum reverse leakage current (ID) of 2000 μA at its 5.0 V stand-off voltage (VWM), tested at TA = 25 °C. This parameter is critical for low-power applications such as always-on sensor nodes, where excessive leakage could compromise battery life or cause false wake-up events. The 5KP5.0HE3/54 maintains this leakage specification across its full –55 °C to +175 °C operating junction temperature range.
Can the 5KP5.0HE3/54 be used in bidirectional signal line protection?
No, the 5KP5.0HE3/54 is unidirectional only, as stated in Vishay's datasheet: "Available in uni-directional polarity only." It is designed for DC power rail protection where polarity is fixed (e.g., 5 V to ground). For bidirectional signal lines such as USB or RS-485, a dedicated bidirectional TVS like SMAJ5.0A or an array device would be required. Using the 5KP5.0HE3/54 on AC or reversible signals risks forward conduction and unintended circuit behavior.
