Product details
Overview
5KP13HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 5 mA, 21.5 V clamping voltage (VC) at 233 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform).
For engineers reviewing the 5KP13HE3/73 datasheet, 5KP13HE3/73 pinout, 5KP13HE3/73 application, or 5KP13HE3/73 equivalent, this device is selected for automotive-grade overvoltage protection where AEC-Q101 qualification, low clamping ratio, and robust 175 °C junction temperature capability are required.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) to transient events such as load dump, inductive switching spikes, and ESD. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction during normal operation.
The device operates with a 0.090 %/°C temperature coefficient of VBR and maintains stable clamping performance across -55 °C to +175 °C junction temperature range. Its 8.0 W steady-state power dissipation (PD) and 600 A IFSM rating support reliable operation under repetitive surge conditions when mounted on adequate thermal mass.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 5 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients. |
| VC @ IPPM | 21.5 V at 233 A - Clamped voltage during 10/1000 μs surge; limits downstream component stress. |
| PPPM | 5000 W - Peak pulse power handling per JEDEC standard waveform; supports high-energy automotive transients. |
| TJ max. | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronic components including temperature cycling and HTRB. |
| Package | P600 - Axial-lead, molded epoxy case with UL 94 V-0 rating; supports manual and wave soldering (275 °C, 10 s max). |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body with cathode band marking; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit; conducts during forward surge (e.g., load dump polarity reversal). |
| Cathode | Clamping terminal | Marked by color band; connected to higher-potential rail; initiates avalanche breakdown when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |

| AEC-Q101 qualification | Validates reliability for automotive powertrain and body electronics applications requiring extended temperature and lifetime validation. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes voltage overshoot during surge, reducing stress on downstream MOSFETs, controllers, and sensors. |
| 175 °C maximum junction temperature | Supports mounting near heat-generating components (e.g., DC/DC converters) without derating in engine compartment designs. |
| UL 94 V-0 molding compound | Ensures flame resistance in safety-critical automotive and industrial enclosures where flammability compliance is mandated. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients up to 35 V and 100 ms duration. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and input filter capacitor.

Use Scenario: Protecting LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at connector entry point. Use Value: Provides <2 μA leakage at 13 V while clamping 8 kV contact ESD to <30 V, meeting ISO 10605 Class 3 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHE3/52 | Lower PPPM (600 W), SMC package, same VWM (13 V), higher VC (21.5 V), AEC-Q101 qualified. | Designed for PCB space-constrained applications; not suitable for >1 kA surge events due to lower energy rating. | Select SMBJ13AHE3/52 only when board area is critical and peak surge current remains below 30 A. |
| 1.5KE13A-E3/54 | Same VWM (13 V), lower PPPM (1500 W), DO-201 package, non-AEC-Q101, higher VC (23.0 V). | Intended for commercial-grade power supplies; lacks automotive qualification and thermal robustness. | Choose 1.5KE13A-E3/54 only for cost-sensitive non-automotive applications with verified surge energy <1500 W. |
Compared with SMBJ13AHE3/52 and 1.5KE13A-E3/54, the 5KP13HE3/73 delivers 3.3× higher peak pulse power and AEC-Q101 validation-making it the sole option among the three for under-hood automotive load dump protection where sustained 5000 W dissipation and 175 °C operation are mandatory.

FAQ
What is the clamping voltage of the 5KP13HE3/73 under maximum rated surge current?
The 5KP13HE3/73 clamps to 21.5 V at its rated peak pulse current of 233 A (10/1000 μs waveform). This value is measured and guaranteed per JEDEC test conditions and defines the maximum voltage imposed on protected circuitry during worst-case transient events. The clamping voltage remains stable across the full operating temperature range from -55 °C to +175 °C.
Is the 5KP13HE3/73 suitable for automotive under-hood applications?
Yes, the 5KP13HE3/73 is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood automotive applications such as engine control units, body control modules, and ADAS power supplies. Its P600 package provides mechanical robustness and thermal mass needed for sustained high-temperature operation.
What does the "HE3" suffix indicate in 5KP13HE3/73?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. It distinguishes the automotive-grade version from the commercial "E3" variant (e.g., 5KP13A-E3/54), confirming enhanced reliability testing for automotive use cases including temperature cycling, highly accelerated life testing, and biased humidity testing.
How does the 5KP13HE3/73 compare to bidirectional TVS diodes in surge protection?
The 5KP13HE3/73 is unidirectional and intended for DC-biased circuits where reverse conduction must be avoided during normal operation. Unlike bidirectional variants, it blocks reverse current up to -13 V while clamping positive transients above +14.4 V. This makes it ideal for protecting 12 V battery rails without introducing leakage paths during quiescent states.
Can the 5KP13HE3/73 replace older 1.5KE series TVS diodes in existing designs?
No direct replacement is recommended without redesign verification. While both share 13 V stand-off voltage, the 5KP13HE3/73 delivers 5000 W peak pulse power versus 1500 W for 1.5KE13A, requiring larger PCB copper area and thermal management. Its P600 package also differs mechanically from DO-201, necessitating layout changes and revalidation of surge immunity performance.
