Product details
Overview
5KP16AHE3_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 16.0 V stand-off voltage (VWM), 26.0 V max clamping voltage (VC) at 192 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs in automotive power supplies against lightning and inductive switching transients.
For engineers reviewing the 5KP16AHE3_A/C datasheet, 5KP16AHE3_A/C pinout, 5KP16AHE3_A/C application, or 5KP16AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity requirement, AEC-Q101 qualification status, thermal derating above 25 °C, and compatibility with P600 PCB footprints and lead-free reflow profiles.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during overvoltage events, leveraging a glass-passivated P600 junction to sustain repetitive 5000 W pulses at 0.01 % duty cycle. Its 17.8–19.7 V breakdown range (VBR at 5 mA) ensures reliable turn-on before system damage, while low incremental surge resistance enables stable clamping across wide current ranges.
The device is optimized for DC power rail protection where fast response (<1 ns), low leakage (<2.0 μA at 16.0 V), and high IFSM (500 A, 8.3 ms half-sine) are required. Its -55 °C to +175 °C operating junction temperature range supports under-hood automotive deployment without external heatsinking beyond standard PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16.0 V - Maximum continuous reverse working voltage before leakage exceeds 2.0 μA; defines safe operating ceiling for normal circuit conditions. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown occurs within this band at 5 mA test current; ensures predictable turn-on margin above VWM. |
| VC @ IPPM | 26.0 V - Clamped voltage at 192 A peak pulse (10/1000 μs); determines maximum stress imposed on protected downstream components. |
| PPPM | 5000 W - Peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 5a without failure. |
| IFSM | 500 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports robustness against accidental reverse-bias misapplication or fault currents. |
| TJ max. | +175 °C - Maximum junction temperature; allows operation in high-ambient environments such as engine control units with minimal thermal design overhead. |
| Polarity | Unidirectional - Cathode-marked device; blocks reverse current until breakdown, suitable for DC supply line protection only. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 22-B102 solderability requirements. Cathode indicated by color band.

IC Role / Device Role / Timing Role: Unidirectional shunt clamp across H-bridge supply rails, activated only during positive overvoltage events. Use Value: Reduces need for oversized gate drivers by limiting rail overshoot to 26.0 V-within safe SOA of 30 V-rated MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower PPPM (600 W), smaller SMB package, same VWM (16 V), higher VC (26.0 V), non-AEC-Q101 | Not qualified for automotive under-hood use; limited to consumer/industrial board-level protection | Select when space-constrained layouts prohibit P600 footprint and surge energy remains below 600 W. |
| 1.5KE16A | Same VWM (16 V), lower PPPM (1500 W), DO-201 package, AEC-Q101 not claimed, VF = 3.5 V | Lacks automotive qualification and 5000 W capability; suitable only for low-energy point-of-load protection | Choose for cost-sensitive legacy designs where 1500 W clamping suffices and P600 thermal mass is unnecessary. |
Compared with SMBJ16A and 1.5KE16A, the 5KP16AHE3_A/C delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 compliance, and provides superior thermal stability in high-ambient environments-making it the sole choice for demanding automotive and industrial power rail protection.

FAQ
What is the clamping voltage of the 5KP16AHE3_A/C at its rated peak pulse current?
The 5KP16AHE3_A/C has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 192 A under 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 surge events. The 5KP16AHE3_A/C maintains this clamping performance across its full operating temperature range, ensuring consistent protection in automotive and industrial environments.
Is the 5KP16AHE3_A/C suitable for automotive applications?
Yes, the 5KP16AHE3_A/C is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and infotainment power supplies. Its P600 package, 175 °C maximum junction temperature, and validated reliability testing-including temperature cycling and HTRB-meet stringent automotive requirements. The 5KP16AHE3_A/C is referenced in Vishay's application notes for load dump and ISO 7637-2 compliance, confirming its suitability for under-hood deployment.
What does the "HE3_A/C" suffix indicate in 5KP16AHE3_A/C?
The "HE3" suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while "_A/C" specifies the preferred package code (C = 13" paper tape and reel, 800 units per reel) and revision level (A). This ordering code confirms the device meets automotive-grade material and packaging standards, including matte tin plating and UL 94 V-0 molding compound. The 5KP16AHE3_A/C is traceable to Vishay Document Number 88308, Revision 16-Mar-2023.
How does the 5KP16AHE3_A/C compare to standard 1.5 kW TVS diodes like 1.5KE16A?
The 5KP16AHE3_A/C offers more than three times the peak pulse power (5000 W vs. 1500 W) and is AEC-Q101 qualified, whereas 1.5KE16A lacks automotive validation and uses a smaller DO-201 package with inferior thermal dissipation. The 5KP16AHE3_A/C also features lower incremental surge resistance and tighter VBR tolerance, resulting in more stable clamping behavior under high-current transients. For applications demanding robust, repeatable protection-especially in automotive power systems-the 5KP16AHE3_A/C is the technically superior solution.
Can the 5KP16AHE3_A/C be used in bidirectional configurations?
No, the 5KP16AHE3_A/C is unidirectional only, with cathode marked by a color band and specified for reverse-biased clamping operation. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a pair of 5KP16AHE3_A/C devices in series opposition-or a dedicated bidirectional part such as 5KP16CA-is required. Using a single 5KP16AHE3_A/C in bidirectional applications risks forward conduction and potential failure during negative excursions.
