Product details
Overview
P4KE16HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 16.8 V maximum breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE16HE3/54 datasheet, P4KE16HE3/54 pinout, P4KE16HE3/54 application, or P4KE16HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 1.0 μA reverse leakage at VWM, and DO-41 leaded package compatibility with through-hole PCB assembly for industrial and automotive surge protection.
Technical Context
This device operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 15.2–16.8 V breakdown range at 1.0 mA test current. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling consistent clamping performance across repetitive transients.
Thermal design relies on RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm), supporting operation up to 175 °C junction temperature. The 1.5 W steady-state power dissipation (PD) and 40 A IFSM rating allow robust handling of 8.3 ms half-sine surges in motor drive and power supply input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA - defines precise clamping activation threshold for overvoltage events |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs against load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp spikes above 13.6 V. Use Value: Limits voltage to ≤22.5 V during 400 W surges, preventing damage to 16 V-rated LDOs and MCU IOs. |
Use Scenario: Shielding analog outputs of pressure or temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS connected across signal and ground lines to absorb fast-rising transients before reaching ADC input. Use Value: Sub-20 ns response time and 22.5 V clamping preserve signal integrity and prevent latch-up in precision front-ends. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Protection |
Use Scenario: Safeguarding AC-DC adapter primary-side rectifier and controller ICs from lightning-induced surges. IC Role / Device Role / Timing Role: Placed across bulk capacitor terminals to suppress line-to-line and line-to-ground transients.

Use Scenario: Preventing gate oxide rupture in N-channel power MOSFETs driven by PWM controllers. IC Role / Device Role / Timing Role: Connected between gate and source to clamp Miller-induced voltage spikes during switching transitions. Use Value: Low clamping voltage (22.5 V) keeps gate-source voltage within safe limits for 20 V-rated MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Surface-mount SMB package (vs. DO-41 through-hole); same 16 V VBR, but 600 W PPPM | Used where board space is constrained and reflow assembly is preferred over wave soldering | Select SMBJ16A for SMT designs requiring higher surge margin; verify thermal pad layout for 600 W dissipation |
| P4KE16A-E3/54 | Same DO-41 package and electrical specs, but commercial-grade (non-AEC-Q101 qualified) | Applicable in non-automotive settings like consumer chargers or industrial HMIs where automotive reliability not mandated | Choose P4KE16A-E3/54 for cost-sensitive, non-automotive programs; retain P4KE16HE3/54 for AEC-Q101 compliance |
Compared with SMBJ16A and P4KE16A-E3/54, P4KE16HE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole mechanical robustness, and verified 175 °C operation - making it the only option qualified for under-hood automotive deployment without redesign.

FAQ
What is the breakdown voltage range of the P4KE16HE3/54?
The P4KE16HE3/54 has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable clamping behavior in overvoltage protection circuits, and the value is confirmed in Vishay's official datasheet revision 16-Sep-2021 (Document Number: 88365). The P4KE16HE3/54 maintains this specification across its qualified temperature range.
Is the P4KE16HE3/54 suitable for automotive applications?
Yes, the P4KE16HE3/54 is AEC-Q101 qualified, explicitly stated in the Vishay datasheet notes and ordering information section. Its construction - including glass-passivated junction, DO-41 package with matte tin leads, and 175 °C maximum junction temperature - meets automotive reliability requirements for under-hood and body-control modules. The HE3 suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade variants like P4KE16A-E3/54.
What is the maximum clamping voltage of the P4KE16HE3/54 during a surge event?
The P4KE16HE3/54 exhibits a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 17.8 A, tested with the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table of the Vishay datasheet and directly determines the voltage stress imposed on protected circuitry during transient events. Engineers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Does the P4KE16HE3/54 have polarity marking, and how is it identified?
Yes, the P4KE16HE3/54 is a unidirectional TVS diode and features a cathode identification band - a visible color stripe on the DO-41 package body. As stated in the Vishay datasheet, "for unidirectional types the color band denotes cathode end." This marking is critical for correct orientation during PCB assembly; reversing the device renders it ineffective for reverse-transient suppression. No marking is present on bidirectional variants, but P4KE16HE3/54 is unidirectional.
What is the steady-state power dissipation rating of the P4KE16HE3/54?
The P4KE16HE3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, per the Maximum Ratings table in the Vishay datasheet. This rating applies to continuous DC or low-duty-cycle conditions - not transient suppression. For reliable long-term operation, designers must ensure thermal management keeps junction temperature below 175 °C, especially in sealed enclosures or high ambient environments.
