Product details
Overview
5KP36HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR at 5.0 mA), and clamps transients to ≤58.1 V at 86.1 A peak pulse current - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP36HE3/73 datasheet, 5KP36HE3/73 pinout, 5KP36HE3/73 application, or 5KP36HE3/73 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, clamping performance under 10/1000 μs surge, thermal derating behavior, and RoHS-compliant lead finish per J-STD-002 - all critical for ESD/surge hardening in automotive and industrial designs.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the 5KP36HE3/73 supports repetitive surge events at 0.01 % duty cycle with full 5000 W capability at TA = 25 °C - derating linearly above 25 °C per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before leakage exceeds 2 μA; defines safe DC bias margin. |
| VBR (min/max) | 40.0 V / 44.2 V at 5.0 mA - Confirmed breakdown range ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤58.1 V at 86.1 A - Clamping voltage limits downstream IC stress during 10/1000 μs surges. |
| PPPM | 5000 W - Peak pulse power handling capacity with 10/1000 μs waveform; validates robustness against lightning-induced transients. |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Qualification | AEC-Q101 qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
| Leakage @ VWM | ≤2.0 μA - Low reverse leakage preserves efficiency in battery-powered or low-quiescent systems. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 22-B102 solderability standards. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side of protected circuit (e.g., ground or return line). |
| Cathode | Clamping node | Connected to higher-potential rail (e.g., +12 V supply); color band marks this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without cascaded TVS stages. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics where field failure risk must be minimized. |
| Glass-passivated junction | Ensures stable VBR and low leakage over lifetime, even under humidity and thermal cycling stress. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during clamping, reducing stress on downstream MOSFETs and controllers. |
| RoHS-compliant, whisker-tested (JESD 201 Class 2) | Supports long-term reliability in automated assembly and high-reliability applications without tin whisker risk. |
Applications
| Automotive Power Supply Output Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V switched-mode power supply outputs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between output rail and ground to shunt surge energy before it reaches downstream regulators or microcontrollers. Use Value: Withstands 5000 W surges while clamping to ≤58.1 V, preventing damage to 36 V-rated input stages in automotive ECUs. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and inductive switching noise in factory automation. IC Role / Device Role / Timing Role: Fast-response TVS connected across differential or single-ended signal lines to divert sub-100 ns ESD pulses. Use Value: Sub-1 ns response time and ≤2 μA leakage preserve signal integrity and measurement accuracy in precision 4–20 mA loops. |
| Telecom DC Feeder Line Protection | Consumer Power Adapter Secondary-Side Clamp |
Use Scenario: Safeguarding PoE-powered equipment front-ends against induced surges on 48 V DC feeder lines. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input stage, coordinated with upstream fusing to allow resettable protection. Use Value: 86.1 A peak pulse current rating and 175 °C TJ enable reliable operation in sealed telecom cabinets with limited airflow. |
Use Scenario: Adding secondary-side surge immunity to AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Unidirectional TVS placed across output capacitor to absorb flyback spikes from transformer leakage inductance. Use Value: 36 V VWM aligns with common 5 V/12 V adapter outputs; P600 package allows manual or automated through-hole assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Lower peak power (600 W), smaller SMB package, same 36 V VWM. | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and low-energy transients. | Select when space-constrained PCB layout prioritizes footprint over surge robustness. |
| 1.5KE36A | Same 5000 W rating but TO-204AA (DO-204AB) package; no AEC-Q101 qualification. | Lacks automotive qualification; requires additional validation for under-hood use. | Choose only for cost-sensitive industrial applications where AEC-Q101 is not mandated. |
Compared with SMBJ36A and 1.5KE36A, the 5KP36HE3/73 uniquely combines AEC-Q101 qualification, P600 thermal mass for sustained surge dissipation, and verified 5000 W capability - making it the only option among the three qualified for automotive power rail protection without design revalidation.

FAQ
What is the clamping voltage of the 5KP36HE3/73 under maximum rated surge current?
The 5KP36HE3/73 clamps to a maximum of 58.1 V when subjected to its rated 86.1 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is the 5KP36HE3/73 suitable for automotive applications?
Yes - the 5KP36HE3/73 carries AEC-Q101 qualification and operates up to 175 °C junction temperature, making it suitable for under-hood and body electronics applications. Its P600 package provides thermal mass needed for repeated surge events in automotive power distribution networks.
How does the 5KP36HE3/73 differ from the 5KP36A variant?
The 5KP36HE3/73 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance to the base 5KP36A specification. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but the HE3 suffix confirms automotive-grade reliability testing and enhanced lead finish robustness.
What is the maximum reverse leakage current of the 5KP36HE3/73 at its stand-off voltage?
At 36 V reverse bias (VWM) and 25 °C ambient, the 5KP36HE3/73 exhibits a maximum reverse leakage current of 2.0 μA. This low leakage preserves efficiency in always-on systems and avoids false triggering in high-impedance sensing nodes.
Can the 5KP36HE3/73 be used in bidirectional configurations?
No - the 5KP36HE3/73 is unidirectional only, with cathode marked by a color band. For bidirectional surge protection, a pair of 5KP36HE3/73 devices in series opposition or a dedicated bidirectional TVS (e.g., 5KP36CA) must be used.
