Product details
Overview
P4KE36HE3/54 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 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V standoff voltage (VWM), 400 W peak pulse power (10/1000 μs), 8.0 A peak pulse current (IPPM), and 49.9 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE36HE3/54 datasheet, P4KE36HE3/54 pinout, P4KE36HE3/54 application, or P4KE36HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, thermal resistance (RθJL = 66 °C/W), and real-world use cases in ESD/surge-prone subsystems.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and matte tin-plated leads compliant with J-STD-002. Its 175 °C max junction temperature and 0.099 %/°C VBR temperature coefficient support stable operation across automotive and industrial ambient ranges.
The device meets AEC-Q101 qualification (HE3 suffix), supports 40 A IFSM surge rating (8.3 ms half-sine), and exhibits low incremental surge resistance - enabling robust protection against inductive switching spikes and lightning-induced surges without latch-up or thermal runaway.
Key Specifications

|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA test current - defines reliable conduction onset under transient overvoltage |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 49.9 V at 8.0 A - clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 400 W - peak transient energy absorption capability per single pulse (duty cycle ≤ 0.01 %) |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
| TJ range | -55 °C to +175 °C - enables deployment in under-hood automotive and high-temp industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Applications
| Automotive Sensor Protection | Industrial Power Supply Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional clamping element placed between signal line and ground, activated within <1 ns of overvoltage event. Use Value: Limits transient voltage to ≤49.9 V, preventing damage to 3.3 V/5 V interface ICs while maintaining signal integrity during normal operation. |
Use Scenario: Safeguarding AC-DC converter primary-side rectifiers and DC-DC controller inputs against line surges and inductive kickback. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor across bulk capacitor or bridge rectifier output. Use Value: Absorbs up to 400 W for 1 ms, reducing risk of MOSFET avalanche failure and enabling smaller input filter design. |
| Consumer Power Adapter Output | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage protection in USB PD and QC-compliant wall adapters to prevent damage to connected devices. IC Role / Device Role / Timing Role: Clamping diode placed between regulated 5–20 V output and ground, responding to feedback loop failures or transient coupling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package, 600 W PPPM, 58.1 V VC, RθJA = 40 °C/W | Higher power handling but larger footprint; better suited for board space-constrained designs needing >400 W | Select SMBJ36A when higher surge margin or lower thermal resistance is required; requires PCB layout revision. |
| 1.5KE36A | DO-201AD package, 1500 W PPPM, 58.1 V VC, 1.5 A IDRM leakage at VWM | Higher peak power but slower response due to larger junction capacitance; not AEC-Q101 qualified | Choose 1.5KE36A only for non-automotive industrial applications where cost-per-watt is prioritized over qualification and speed. |
Compared with SMBJ36A and 1.5KE36A, the P4KE36HE3/54 offers AEC-Q101 validation, tighter VBR tolerance (±5 %), and optimized thermal performance in compact DO-41 - making it preferred for automotive and high-reliability embedded systems where qualification and consistent clamping behavior are mandatory.

FAQ
What is the breakdown voltage range of the P4KE36HE3/54?
The P4KE36HE3/54 has a specified breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is the P4KE36HE3/54 suitable for automotive applications?
Yes, the P4KE36HE3/54 is AEC-Q101 qualified (denoted by HE3 suffix) and rated for -55 °C to +175 °C junction temperature. Its glass-passivated junction, matte tin plating, and validated surge performance make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical.
How does the clamping voltage of P4KE36HE3/54 compare to its standoff voltage?
The P4KE36HE3/54 has a standoff voltage (VWM) of 30.8 V and a maximum clamping voltage (VC) of 49.9 V at 8.0 A peak pulse current. This 1.62× ratio reflects effective transient suppression while maintaining sufficient margin above normal operating voltage - crucial for avoiding false triggering in 24 V automotive or 36 V industrial systems.
What packaging format is used for the P4KE36HE3/54?
The P4KE36HE3/54 is supplied in 13" diameter paper tape and reel packaging (package code 54), with 5500 units per reel. This format supports automated SMT placement via standard pick-and-place equipment, and the DO-41 axial lead configuration allows both through-hole and selective reflow assembly.
Does the P4KE36HE3/54 have bidirectional capability?
No, the P4KE36HE3/54 is a unidirectional TVS diode - indicated by the absence of "CA" suffix. It conducts only in forward bias and clamps reverse transients, requiring correct polarity installation (cathode band toward higher potential). For bidirectional protection, models like P4KE36CA would be required instead.
