Product details
Overview
P6KE36CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 34.2 V minimum and 37.8 V maximum breakdown voltage at 1.0 mA test current, 30.8 V stand-off voltage, 49.9 V maximum clamping voltage at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE36CHE3/54 datasheet, P6KE36CHE3/54 pinout, P6KE36CHE3/54 application, or P6KE36CHE3/54 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant HE3 whisker-tested leads, and thermal resistance of 20 °C/W junction-to-lead - critical for high-reliability transient protection in constrained PCB layouts.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 30.8 V), then rapidly avalanches to low dynamic impedance when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The P6KE36CHE3/54 is rated for 175 °C maximum junction temperature and exhibits 0.099 %/°C temperature coefficient of VBR. It supports repetitive 10/1000 μs surges at 0.01 % duty cycle and withstands solder dip up to 275 °C for 10 s per JESD 22-B106 - confirming suitability for automated assembly in automotive-grade production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA - defines precise avalanche initiation window for predictable clamping onset |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 49.9 V at 12.0 A - clamping voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPPM | 600 W - peak transient power handling capacity, enabling robust protection against lightning-induced surges |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports sustained surge dissipation without thermal runaway |
| TJ max | 175 °C - extended junction temperature range allows operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive electronics per stress-test requirements including HTOL, TCT, 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 |
|---|---|---|---|
| SMBJ36CA | Same VBR range (36.0–40.0 V), but SMC (DO-214AB) package - larger footprint, higher IPPM (32.4 A), lower RθJA | Preferred where board space permits and higher surge margin is needed; not drop-in due to different pad layout | Select SMBJ36CA when >25 A surge current headroom or improved thermal performance is required. |
| 1.5KE36CA | Same DO-204AC package and bi-directional function, but 1.5 kW rating - larger die, higher VC (58.1 V), higher leakage at VWM | Used in legacy designs requiring higher energy absorption; less precise clamping than P6KE36CHE3/54 | Choose 1.5KE36CA only if system-level testing confirms acceptable clamping voltage margin at 58.1 V. |
Compared with SMBJ36CA and 1.5KE36CA, the P6KE36CHE3/54 delivers optimal balance of AEC-Q101 qualification, JEDEC whisker-tested leads, and tight 34.2–37.8 V VBR tolerance - making it preferred for new automotive and industrial designs where reliability, consistency, and RoHS/whisker compliance are mandatory.

FAQ
What does the 'HE3' suffix indicate on P6KE36CHE3/54?
The HE3 suffix on P6KE36CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - confirming suitability for automotive applications and high-reliability solder joints. This distinguishes it from commercial-grade E3 variants and ensures compliance with stringent automotive manufacturing standards.
Is P6KE36CHE3/54 uni-directional or bi-directional?
P6KE36CHE3/54 is a bi-directional TVS diode, as confirmed by the 'CA' designation implied in its family naming convention and explicit documentation stating bi-directional types use the CA suffix. Its symmetrical structure clamps both positive and negative transients without polarity dependence - verified in the Electrical Characteristics table where VBR applies in both directions.
What is the maximum clamping voltage of P6KE36CHE3/54 at rated surge current?
The maximum clamping voltage of P6KE36CHE3/54 is 49.9 V at 12.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is specified in the Electrical Characteristics table and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE36CHE3/54 replace P6KE36A in an existing design?
No - P6KE36CHE3/54 is bi-directional (CA-type), while P6KE36A is uni-directional. Substituting them requires verifying circuit topology: P6KE36A has a cathode band and conducts only in reverse bias, whereas P6KE36CHE3/54 clamps symmetrically. Direct replacement may cause malfunction in polarity-sensitive configurations.
What is the thermal resistance from junction to lead for P6KE36CHE3/54?
The typical thermal resistance from junction to lead (RθJL) for P6KE36CHE3/54 is 20 °C/W, as published in the Thermal Characteristics section. This parameter directly impacts surge survivability - lower RθJL enables faster heat transfer from the silicon junction to the PCB traces through the leads during repetitive transient events.
