Product details
Overview
P6KE36CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 34.2 V to 37.8 V breakdown voltage (VBR) at 1 mA, 30.8 V standoff voltage (VWM), 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the P6KE36CAHE3/54 datasheet, P6KE36CAHE3/54 pinout, P6KE36CAHE3/54 application, or P6KE36CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), then rapidly switches to low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping across temperature (tempco = 0.099 %/°C).
Designed for repetitive surge events at ≤0.01 % duty cycle, it sustains 600 W peak pulse power and handles 100 A non-repetitive forward surge (IFSM) while maintaining TJ ≤ 175 °C. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 49.9 V at 12.0 A - limits transient voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 600 W - peak surge energy absorption capacity per single 10/1000 μs pulse |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB layout and heatsinking decisions |
| AEC-Q101 | Qualified - validated for automotive electronics reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; bidirectional configuration has no polarity marking. Leads are solderable per J-STD-002 and JESD 22-B102; 275 °C max solder dip for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Case | Mechanical mounting surface | Non-electrical; provides mechanical stability and thermal path via leadframe to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|

|---|---|
Use Scenario: Suppressing load-dump transients (up to 120 V) on 12 V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Shunt TVS placed between power rail and chassis ground to clamp surges before they reach LDOs or microcontrollers. Use Value: Prevents latch-up or gate oxide damage in downstream ICs during ISO 7637-2 Pulse 5a events due to its 49.9 V clamping at 12 A and +175 °C rating. | Use Scenario: Protecting 4–20 mA current-loop sensor inputs from ESD and lightning-induced surges in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional TVS connected across input terminals to divert ±15 kV ESD (IEC 61000-4-2) and 1 kV ring-wave transients. Use Value: Maintains signal integrity below 30.8 V standby while clamping to 49.9 V during surge - preserving analog front-end accuracy and avoiding false triggers. |
| Telecom Line Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Guarding RS-485 transceiver bus lines against induced surges from nearby AC wiring in building management systems. IC Role / Device Role / Timing Role: Differential-mode TVS pair (one per line) referenced to common ground, leveraging bidirectional symmetry. Use Value: Enables robust communication up to 10 Mbps by limiting transient overvoltage to <50 V - within RS-485 common-mode range and below transceiver absolute max ratings. | Use Scenario: Safeguarding microcontroller GPIOs and gate drivers from back-EMF spikes generated by brushed DC motors in smart home appliances. IC Role / Device Role / Timing Role: Local TVS mounted at motor connector to absorb inductive kickback before propagation into control board. Use Value: Eliminates need for snubber RC networks by providing sub-1 ns response and 600 W surge handling - reducing BOM count and PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Same VWM/VC, but SMB package (smaller footprint, higher RθJA = 110 °C/W) | Better suited for space-constrained consumer PCBs; less suitable for high-ambient-temperature automotive use | Select SMBJ36CA only if board area is critical and thermal margin allows higher junction temperature rise |
| 1.5KE36CA | Same electrical specs, but larger DO-201 package (higher IPPM = 13.9 A, lower RθJA = 60 °C/W) | Preferred for industrial power supplies where higher surge repetition and thermal robustness are required | Choose 1.5KE36CA when designing for >1000 surge cycles or ambient >105 °C |
Compared with SMBJ36CA and 1.5KE36CA, P6KE36CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-15 manufacturability, and thermal performance for cost-sensitive automotive and industrial modules - without requiring PCB redesign or derating penalties.

FAQ
What is the clamping voltage of P6KE36CAHE3/54 at its rated peak pulse current?
The P6KE36CAHE3/54 has a maximum clamping voltage (VC) of 49.9 V at 12.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and ensures protected circuits remain below critical voltage thresholds during surge events. The clamping performance is consistent across both polarities due to its bidirectional design.
Is P6KE36CAHE3/54 suitable for automotive applications?
Yes, P6KE36CAHE3/54 is AEC-Q101 qualified and specifically intended for automotive use. Its HE3 suffix denotes compliance with AEC-Q101 stress tests including temperature cycling, high-temperature reverse bias, and ESD. With a maximum junction temperature of +175 °C and UL 497B recognition, P6KE36CAHE3/54 meets requirements for engine control units, body electronics, and ADAS power domains.
How does the bidirectional configuration of P6KE36CAHE3/54 affect its circuit placement?
The bidirectional configuration of P6KE36CAHE3/54 means it has no polarity marking and functions identically in either orientation. It is placed directly across the protected nodes - such as between a signal line and ground, or across differential pairs - without regard to anode/cathode direction. This simplifies layout and eliminates orientation errors during automated assembly.
What is the standoff voltage rating for P6KE36CAHE3/54, and why is it important?
P6KE36CAHE3/54 has a maximum standoff voltage (VWM) of 30.8 V, meaning it remains non-conductive with leakage <1 μA up to this DC or RMS voltage. This rating ensures reliable operation in 24 V industrial systems and 12 V automotive circuits where normal operating voltages must not trigger clamping. Exceeding VWM risks premature conduction and power loss.
Does P6KE36CAHE3/54 require a heatsink for standard operation?
No, P6KE36CAHE3/54 does not require an external heatsink under typical surge conditions because its 600 W peak pulse power is dissipated in sub-millisecond events. However, its thermal resistance (RθJA = 75 °C/W) means sustained power dissipation above 5.0 W (its rated DC power, PD) will cause overheating - so it must be used only for transient suppression, not continuous regulation. PCB copper area acts as sufficient thermal mass for pulsed operation.
