Product details
Overview
P6KE36CA-E3/1 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics in signal and power lines. It features a 36 V breakdown voltage (VBR min/max = 34.2–37.8 V), 30.8 V stand-off voltage (VWM), 49.9 V clamping voltage at 12.0 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6KE36CA-E3/1 datasheet, P6KE36CA-E3/1 pinout, P6KE36CA-E3/1 application, or P6KE36CA-E3/1 equivalent, key selection criteria include bi-directional clamping symmetry, DO-204AC package compatibility, UL 497B recognition, AEC-Q101 qualification status, and thermal resistance (RθJL = 20 °C/W) for board-level surge resilience validation.
Technical Context
This device implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1 ns) and low dynamic impedance under high-current surges. Its bi-directional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
Rated for 600 W peak pulse power with 10/1000 μs waveform and 0.01% duty cycle, it sustains repetitive transients while maintaining stable VC ≤ 49.9 V at IPPM = 12.0 A. Thermal design leverages RθJL = 20 °C/W to support lead-temperature-limited derating up to TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - ensures reliable avalanche conduction onset within ±5% tolerance at 1.0 mA test current |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 49.9 V at 12.0 A - clamped voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| TJ range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial ambient environments |
| RθJL | 20 °C/W - enables thermal management via PCB copper pour or lead-frame heat sinking |
| UL Recognition | QVGQ2 file E136766 - certified per UL 497B for telecom and data line protector classification |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Bi-directional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 VWM (30.8 V) and VC (59.0 V), but lower PPPM (600 W same), smaller SMB package (DO-214AA), higher IPPM (10.1 A) | Preferred where board space is constrained and thermal coupling to PCB is enhanced via surface-mount layout | Select when footprint reduction and automated assembly are prioritized over through-hole mechanical robustness |
| 1.5KE36CA | Same VBR/VWM/VC, identical DO-204AC package, but higher PPPM (1500 W) and IPPM (30.0 A) | Used in higher-energy threat environments such as AC mains input stages or outdoor telecom enclosures | Choose when system-level surge testing requires >600 W margin or legacy 1.5KE footprint compatibility is mandatory |
Compared with SMBJ36CA and 1.5KE36CA, the P6KE36CA-E3/1 delivers optimal balance of proven through-hole mechanical stability, AEC-Q101 qualification, and UL 497B recognition - making it preferred for automotive and industrial control applications where reliability under vibration and thermal cycling is critical.

FAQ
What is the polarity configuration of P6KE36CA-E3/1?
The P6KE36CA-E3/1 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or floating signal lines where polarity cannot be guaranteed. This distinguishes it from uni-directional variants like P6KE36A, which feature a cathode band and conduct only in reverse bias.
Does P6KE36CA-E3/1 meet automotive qualification standards?
Yes, the P6KE36CA-E3/1 is RoHS-compliant and manufactured to Vishay's commercial-grade specification. While the base E3 suffix is not AEC-Q101 qualified, the HE3 variant (e.g., P6KE36CAHE3/1) carries full AEC-Q101 qualification. Engineers selecting P6KE36CA-E3/1 for automotive use must verify qualification status per order code and consult Vishay's official documentation for application-specific compliance evidence.
What is the maximum clamping voltage of P6KE36CA-E3/1 under surge conditions?
The maximum clamping voltage (VC) of P6KE36CA-E3/1 is 49.9 V at a peak pulse current (IPPM) of 12.0 A, measured using the standard 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does P6KE36CA-E3/1 differ from P6KE36A?
The P6KE36CA-E3/1 is bi-directional, whereas P6KE36A is uni-directional. The "CA" suffix denotes symmetrical clamping behavior with no polarity marking, enabling use in AC or differential signal paths. In contrast, P6KE36A has a cathode band and conducts only in reverse bias, requiring correct orientation during placement. Both share identical VBR, VWM, and PPPM ratings but serve distinct circuit topologies.
Is P6KE36CA-E3/1 UL-recognized for telecom applications?
Yes, P6KE36CA-E3/1 is UL-recognized under file E136766 with QVGQ2 classification per UL 497B for protectors used in telecommunications circuits. This recognition validates its suitability for primary and secondary protection in DSL, T1/E1, and other telecom line interfaces - reducing system-level certification burden when designing to GR-1089-CORE or ITU-T K-series standards.
