Product details
Overview
P6KE36C-E3/54 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 breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE36C-E3/54 datasheet, P6KE36C-E3/54 pinout, P6KE36C-E3/54 application, or P6KE36C-E3/54 equivalent, key selection criteria include bi-directional clamping symmetry, low thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and compatibility with 8.3 ms surge waveforms per JESD22-B106 soldering standards.
Technical Context
The P6KE36C-E3/54 operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 30.8 V), but triggers into low-impedance conduction when transient voltage exceeds its 34.2–37.8 V breakdown range. Its glass-passivated junction enables fast response (<1 ns) and stable clamping across temperature.
It supports bi-directional protection without polarity marking, delivers 600 W peak pulse power at 25 °C with derating above TA = 25 °C, and maintains clamping performance up to 175 °C junction temperature. The device is rated for 100 A non-repetitive forward surge (IFSM) and exhibits 0.099 %/°C temperature coefficient of VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe working margin below breakdown |
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA test current - ensures reliable triggering across manufacturing tolerance and temperature |
| VC @ IPPM | 49.9 V at 12.0 A (10/1000 µs) - limits downstream voltage stress during worst-case surge events |
| PPPM | 600 W - sustains high-energy transients common in automotive load-dump or inductive switching scenarios |
| TJ max | 175 °C - enables operation in under-hood or industrial environments without thermal shutdown |
| RθJL | 20 °C/W - allows efficient heat transfer to PCB copper or lead frame, critical for repetitive surge handling |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (unmarked) | Bi-directional terminal pair | No polarity marking required; symmetric conduction in both directions enables single-device protection of AC or differential lines |
| Leads (anode & cathode) | Thermal and electrical interface | Lead-to-junction thermal resistance of 20 °C/W enables effective heat dissipation into PCB copper pour or chassis mount |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR and low leakage over lifetime; eliminates risk of junction corrosion in humid or chemically aggressive environments |
| 600 W peak pulse power (10/1000 µs) | Withstands automotive load-dump surges (ISO 7637-2 Pulse 5a) and industrial inductive kickback without degradation |
| Bi-directional configuration (C suffix) | Protects AC-coupled or floating signal paths (e.g., RS-485, CAN bus, sensor bridges) without requiring external polarity management |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic-level components |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

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 | DO-214AA package; 36 V VWM, 40.0 V VC @ 15.3 A; lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount layouts with limited board space; higher IPPM but same clamping voltage class | Select SMBJ36CA when SMT assembly, tighter thermal budget, or higher surge repetition rate is required. |
| 1.5KE36CA | DO-201AD package; identical VWM/VBR/VC specs; 1500 W PPPM; larger footprint and higher IFSM (200 A) | Used where higher single-pulse energy absorption is needed (e.g., heavy industrial motor drives) | Choose 1.5KE36CA only if system-level testing confirms need for >600 W pulse handling; otherwise P6KE36C-E3/54 offers optimal cost/size balance. |
Compared with SMBJ36CA and 1.5KE36CA, P6KE36C-E3/54 provides AEC-Q101 qualification in a cost-optimized through-hole DO-15 package - making it preferred for automotive and industrial applications requiring proven reliability without SMT rework or oversized footprints.

FAQ
What does the "C" suffix in P6KE36C-E3/54 indicate?
The "C" suffix denotes bi-directional functionality: P6KE36C-E3/54 clamps voltage transients equally in both polarities, with no cathode marking and symmetric VBR and VC characteristics. This makes P6KE36C-E3/54 ideal for AC signal lines, differential buses like RS-485, or any application where polarity reversal or floating references occur - unlike uni-directional variants such as P6KE36A-E3/54.
Is P6KE36C-E3/54 suitable for automotive applications?
Yes, P6KE36C-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay documentation. Its 175 °C maximum junction temperature, robust glass-passivated junction, and validated performance under temperature cycling and humidity testing make P6KE36C-E3/54 appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
How does the clamping voltage of P6KE36C-E3/54 compare to its breakdown voltage?
P6KE36C-E3/54 has a minimum breakdown voltage (VBR) of 34.2 V and a maximum clamping voltage (VC) of 49.9 V at 12.0 A (10/1000 µs). This yields a clamping ratio of ~1.46 - indicating tight voltage control during surge events. That ratio ensures protected circuits experience minimal overvoltage beyond nominal rail levels, which is essential for safeguarding modern low-voltage ICs in P6KE36C-E3/54-protected systems.
What is the meaning of the "E3/54" suffix in P6KE36C-E3/54?
"E3" indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads passing JESD 201 Class 1A whisker testing. "/54" specifies the preferred package code for 13-inch paper tape and reel delivery, with 4000 units per reel. This packaging format ensures automated placement compatibility and traceable lot control - critical for high-volume manufacturing using P6KE36C-E3/54 in production lines.
Can P6KE36C-E3/54 replace P6KE36A-E3/54 in a design?
No - P6KE36C-E3/54 is bi-directional while P6KE36A-E3/54 is uni-directional, with different polarity marking (cathode band) and asymmetric IV behavior. Substituting P6KE36C-E3/54 for P6KE36A-E3/54 in a DC-biased circuit may cause unintended conduction or failed protection. Always verify circuit topology: use P6KE36C-E3/54 only where true bi-directional clamping is required, and retain P6KE36A-E3/54 for standard DC rail protection.
