Product details
Overview
5KP36A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 5.0 mA, 58.1 V maximum clamping voltage (VC) at 86.1 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supplies, industrial motor drives, and telecom interface protection.
For engineers reviewing the 5KP36A-E3/51 datasheet, 5KP36A-E3/51 pinout, 5KP36A-E3/51 application, or 5KP36A-E3/51 equivalent, this page delivers verified electrical parameters, P600 package dimensions, clamping behavior under surge stress, thermal derating curves, and AEC-Q101 qualification status for automotive-grade reliability assessment.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device in parallel with sensitive circuitry. Its P600 glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping across repetitive transients up to 0.01% duty cycle.
The 5KP36A-E3/51 is rated for -55 °C to +175 °C operating junction temperature, supports 600 A non-repetitive forward surge current (IFSM), and exhibits 0.104 %/°C temperature coefficient of VBR - ensuring predictable voltage threshold shift across wide thermal ranges in engine control units and industrial inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 36.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 40.0–44.2 V at 5.0 mA - Confirmed avalanche onset range; ensures reliable triggering during overvoltage events. |
| VC (Clamping Voltage) | 58.1 V at 86.1 A (10/1000 μs) - Peak voltage seen by protected IC during worst-case surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 5000 W - Sustained energy absorption capability without failure; suitable for lightning-induced surges per IEC 61000-4-5 Level 4. |
| IR (Reverse Leakage) | 2.0 μA at VWM - Minimal standby power loss and signal integrity impact in always-on systems like CAN bus nodes. |
| TJ max. | +175 °C - Enables placement near heat-generating components (e.g., MOSFETs, gate drivers) without thermal derating penalties. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, UL 94 V-0 rated; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration. |
| Cathode | Current exit during reverse-biased clamping | Connected to protected line (e.g., 36 V rail); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe transients such as load dump (ISO 7637-2) without cascaded TVS staging. |
| P600 glass-passivated chip junction | Ensures robust surge endurance and long-term parameter stability under repeated stress, critical for 15+ year automotive service life. |
| AEC-Q101 qualification | Validates reliability for under-hood applications including engine control modules, battery management systems, and ADAS power domains. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage overshoot during clamping - preserves margin for 40 V-rated MOSFETs and microcontrollers on same rail. |
| 175 °C max junction temperature | Supports direct mounting on heatsinks or thermally coupled PCB zones in high-ambient environments like EV traction inverters. |
Applications
| Automotive Load Dump Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: Protecting engine control unit (ECU) 36 V supply input from ISO 7637-2 Pulse 5a load dump transients reaching 60 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed directly at ECU power entry point; clamps within <1 ns to limit voltage to ≤58.1 V. Use Value: Prevents latch-up or permanent damage to 40 V-rated buck converters and CAN transceivers without requiring upstream fusing delay. |
Use Scenario: Safeguarding PLC I/O module 36 V backplane against switching transients from solenoid valve actuation. IC Role / Device Role / Timing Role: Standby protection element across rail-to-ground; activated only during >40 V excursions with sub-ns response.

| Telecom Interface Surge Suppression | Renewable Energy Inverter DC Link Protection |
Use Scenario: Shielding RS-485 transceiver power pins in outdoor base station equipment exposed to induced lightning surges. IC Role / Device Role / Timing Role: Secondary-level TVS on local 36 V bias rail feeding isolated data interface ICs. Use Value: Limits clamped voltage to 58.1 V - well below 60 V absolute maximum rating of isolated RS-485 drivers, preserving signal integrity. |
Use Scenario: Protecting DC link capacitors and IGBT gate drivers in solar string inverters subjected to grid-switching transients. IC Role / Device Role / Timing Role: Parallel-connected TVS on 36 V auxiliary supply feeding control logic and sensing circuitry. Use Value: Absorbs 5000 W surges without degradation, enabling compliance with IEC 61000-4-5 (4 kV/2 Ω) without derating for ambient temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Lower PPPM (400 W), SMA package (0.5 W PD), 64.5 V VC at 32.4 A - significantly reduced surge handling. | Suitable only for low-energy signal-line protection; not viable for 36 V power rail or load dump scenarios. | Select 5KP36A-E3/51 when ≥5000 W clamping capacity and AEC-Q101 validation are mandatory. |
| ON Semiconductor 1.5KE36A | Same VWM/VBR range but P600-equivalent P600 package; 58.1 V VC at 86.1 A confirmed; however, not AEC-Q101 qualified. | Acceptable for industrial/commercial use but excluded from automotive OEM BOMs requiring qualification evidence. | Choose 5KP36A-E3/51 where automotive qualification, extended temperature operation, or guaranteed 175 °C TJ max is required. |
Compared with SMAJ36A and 1.5KE36A, the 5KP36A-E3/51 uniquely combines 5000 W surge rating, AEC-Q101 qualification, and 175 °C junction rating - making it the only option validated for under-hood automotive power rail protection without design compromise.

FAQ
What is the clamping voltage of the 5KP36A-E3/51 under a 10/1000 μs surge?
The 5KP36A-E3/51 has a maximum clamping voltage (VC) of 58.1 V at 86.1 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 5KP36A-E3/51 suitable for automotive applications?
Yes, the 5KP36A-E3/51 is AEC-Q101 qualified and rated for -55 °C to +175 °C junction temperature, making it suitable for under-hood automotive applications including engine control units, battery management systems, and ADAS power domains. Its P600 package and glass-passivated junction meet automotive reliability and thermal cycling requirements.
What does the "E3/51" suffix indicate in 5KP36A-E3/51?
The "E3" denotes RoHS-compliant, commercial-grade termination meeting JESD 201 Class 1A whisker testing; "/51" specifies the preferred packaging code - 51 indicates 800-piece tape-and-reel delivery in 13-inch diameter reels per Vishay's ordering convention. This matches documented delivery mode for P600 devices in the 5KP family.
How does the 5KP36A-E3/51 compare to standard 1.5 kW TVS diodes like SMAJ36A?
The 5KP36A-E3/51 delivers 5000 W peak pulse power - more than three times the 400 W rating of SMAJ36A - and uses a P600 package capable of higher thermal dissipation. Unlike SMAJ36A, it is AEC-Q101 qualified and rated for 175 °C operation, making it appropriate for high-stress automotive and industrial power rail protection where lower-power alternatives would fail.
What is the reverse leakage current of the 5KP36A-E3/51 at its stand-off voltage?
The 5KP36A-E3/51 exhibits a maximum reverse leakage current (ID) of 2.0 μA at its 36.0 V stand-off voltage (VWM), measured at 25 °C. This low leakage ensures minimal standby power loss and avoids interference with precision analog or always-on monitoring circuits powered from the same rail.
