Product details
Overview
P6KE36HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 34.2 V minimum breakdown voltage (VBR), 30.8 V maximum stand-off voltage (VWM), 49.9 V clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU power inputs and industrial sensor interfaces.
For engineers reviewing the P6KE36HE3/54 datasheet, P6KE36HE3/54 pinout, P6KE36HE3/54 application, or P6KE36HE3/54 equivalent, this AEC-Q101 qualified TVS offers validated surge immunity for 12 V/24 V systems, low leakage (<1.0 µA at VWM), fast response time, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
The P6KE36HE3/54 operates as a uni-directional avalanche diode, clamping transient overvoltages above its breakdown threshold while maintaining low dynamic impedance during surge events. Its glass-passivated junction ensures stable VBR tolerance (±5%) and repeatable clamping performance across temperature (–55 °C to +175 °C).
It delivers 600 W peak pulse power handling per 10/1000 µs waveform with 0.01% duty cycle, supported by thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient). The device fails short-circuit under severe overload, enabling fuse/circuit breaker coordination for system-level fault containment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 30.8 V - Maximum continuous reverse operating voltage before significant leakage; sets safe margin below system nominal voltage (e.g., 24 V rail) |
| VBR (Breakdown Voltage) | 34.2–37.8 V at 1.0 mA - Avalanche onset range defining reliable turn-on threshold for transients exceeding normal operation |
| VC (Clamping Voltage) | 49.9 V at 12.0 A IPPM - Maximum voltage seen by protected circuit during 600 W surge; determines downstream component stress |
| PPPM (Peak Pulse Power) | 600 W - Sustains standardized 10/1000 µs lightning/surge pulses without degradation when mounted on adequate copper area |
| IPPM (Peak Pulse Current) | 12.0 A - Peak surge current capability at rated clamping voltage; defines minimum series impedance required upstream |
| TJ max. | +175 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Leakage (ID) | ≤1.0 µA at 30.8 V - Negligible standby power loss and no interference with high-impedance sensor bias networks |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.

| RoHS-compliant, matte tin plating | Enables lead-free reflow compatibility and eliminates whisker risk in high-reliability applications |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V power inputs in engine control units (ECUs) against load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed directly at connector entry point, shunting surge energy to ground before reaching DC-DC converters and microcontrollers. Use Value: Limits voltage to ≤49.9 V during 12 A surges, preventing damage to 36 V-rated input stages and ensuring AS-1000 compliance. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors exposed to ESD and cable discharge events. IC Role / Device Role / Timing Role: Uni-directional TVS placed between signal line and local ground, activated only during positive-going transients on the loop supply side. Use Value: Clamps ESD pulses (IEC 61000-4-2 ±8 kV contact) within nanoseconds while adding <1 pF capacitance to preserve signal integrity. |
| Telecom DC Power Feeding Protection | Consumer Appliance Motor Drive Supply Protection |
Use Scenario: Securing remote powering circuits (e.g., PoE midspan injectors) feeding IP cameras and wireless access points over twisted-pair cables. IC Role / Device Role / Timing Role: Standoff-rated TVS on +48 V DC feed line, absorbing induced surges from nearby AC mains or lightning coupling. Use Value: Maintains 30.8 V standoff to avoid false triggering while clamping 600 W transients to protect downstream DC-DC isolation stages. |
Use Scenario: Shielding BLDC motor drive power supplies in smart home appliances (e.g., washing machines) from commutation-induced spikes. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS on 310 V DC bus, suppressing repetitive switching transients without loading the supply during idle periods. Use Value: Survives >100,000 surge cycles due to robust glass-passivated junction, extending product lifetime beyond 10-year consumer warranty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/52 | Lower PPPM (400 W), SMA package (surface-mount), same VWM/VBR range but higher VC (58.1 V) | Preferred for space-constrained PCBs where through-hole mounting is impractical; less robust for repeated high-energy surges | Select when board real estate is limited and surge severity is moderate (e.g., consumer-grade USB ports) |
| 1.5KE36A | Same DO-204AC package and electrical specs, but commercial-grade (non-AEC-Q101), no HE3 whisker qualification | Suitable for non-automotive industrial controls where extended temperature validation is not required | Choose for cost-sensitive applications where AEC-Q101 certification and Class 2 whisker resistance are unnecessary |
Compared with SMAJ36A-E3/52 and 1.5KE36A, the P6KE36HE3/54 uniquely combines AEC-Q101 qualification, 600 W surge capacity, and axial DO-15 form factor - making it optimal for automotive and harsh-environment designs requiring proven reliability and legacy-compatible through-hole assembly.

FAQ
What is the key difference between P6KE36HE3/54 and P6KE36A-E3/54?
The P6KE36HE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, whereas P6KE36A-E3/54 is commercial grade only. Both share identical electrical specs (VWM = 30.8 V, VC = 49.9 V), but P6KE36HE3/54 is validated for automotive under-hood use and high-reliability industrial deployments. The HE3 suffix confirms enhanced process controls and testing rigor applied to each P6KE36HE3/54 unit.
Can P6KE36HE3/54 be used in bi-directional protection applications?
No - P6KE36HE3/54 is strictly a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional protection (e.g., AC lines or data buses), Vishay specifies the "CA" suffix variant (e.g., P6KE36CA). Using P6KE36HE3/54 in reverse-biased configurations risks premature failure due to lack of symmetric avalanche characteristics.
What is the maximum allowable PCB trace length between P6KE36HE3/54 and the protected node?
To maintain effective clamping, the total inductance of the connection path must be minimized. For P6KE36HE3/54, Vishay recommends ≤5 mm total trace length (anode-to-ground + cathode-to-line) to limit inductive voltage overshoot during sub-100 ns transients. Longer traces increase VC beyond 49.9 V, reducing protection margin - especially critical in automotive load-dump scenarios.
Does P6KE36HE3/54 require derating at elevated ambient temperatures?
Yes - P6KE36HE3/54 must be derated above 25 °C ambient per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power drops to ~420 W (70% of 600 W), and at 125 °C, it falls to ~270 W (45%). This derating ensures junction temperature stays within the 175 °C absolute maximum, particularly important in sealed enclosures or near heat-generating components.
How does the glass passivation in P6KE36HE3/54 improve long-term reliability?
Glass passivation protects the silicon junction from moisture ingress, ionic contamination, and mechanical stress during thermal cycling. In P6KE36HE3/54, this results in <0.1%/1000 hrs parametric drift in VBR under 85 °C/85% RH bias testing - critical for automotive modules expected to operate 15+ years without maintenance. It also prevents leakage current increase over time, preserving low-power sensor interface integrity.
