Product details
Overview
5KP15HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 54.0 V stand-off voltage (VWM), and 87.1 V maximum clamping voltage (VC) at 57.4 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP15HE3/54 datasheet, 5KP15HE3/54 pinout, 5KP15HE3/54 application, or 5KP15HE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant HE3 suffix with JESD 201 Class 2 whisker resistance, and P600 package thermal derating per Fig. 5.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protector, triggered when reverse voltage exceeds its 60.0–66.3 V breakdown range (VBR at 5.0 mA). Its glass-passivated P600 junction enables fast response (<1 ns) and low incremental surge resistance to limit transient energy delivered to downstream circuitry.
Designed for crowbar-circuit replacement in switching power supply outputs, it withstands repetitive 10/1000 μs surges at 0.01% duty cycle and dissipates up to 8.0 W on an infinite heatsink at TL = 75 °C - requiring adequate PCB copper area or heatsinking during sustained overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 60.0 V / 66.3 V at 5.0 mA - Ensures reliable turn-on above system nominal voltage with 5% tolerance |
| VC @ IPPM | 87.1 V at 57.4 A - Clamped voltage seen by protected load during 5000 W transient |
| PPPM | 5000 W - Peak pulse power handling capability with 10/1000 μs waveform |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-ambient industrial environments |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling and HTRB |
| Whisker test | JESD 201 Class 2 - Confirmed resistance to tin whisker growth under long-term storage/stress |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; cathode denoted by color band; UL 94 V-0 rated; 0.375" (9.5 mm) body length; lead pitch 0.340–0.360" (8.6–9.1 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side (e.g., ground or return rail) in unidirectional configuration |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 48 V rail); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 5a) without failure |
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications per stress test requirements |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on protected MOSFET gate oxide or IC input structures |
| P600 thermal mass | Supports 8.0 W steady-state dissipation with proper heatsinking - critical for hold-time during slow-decay surges |
| HE3 suffix | RoHS-compliant + JESD 201 Class 2 whisker resistance - ensures long-term solder joint integrity |
Applications
| Automotive Power Supply Protection | Industrial DC Bus Surge Suppression |
|---|---|
Use Scenario: Protecting 48 V battery-fed ECUs against load dump transients (ISO 16750-2) and alternator overshoot. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 48 V rail and chassis ground to clamp transients within safe limits for downstream DC-DC converters. Use Value: Withstands 5000 W pulses while limiting clamped voltage to ≤87.1 V - preserving 100 V-rated MOSFETs and reducing need for oversized input capacitors. | Use Scenario: Safeguarding PLC I/O modules connected to 24–48 V field wiring exposed to lightning-induced surges and inductive kickback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on power input stage, coordinated with upstream fuses to allow resettable fault clearing. Use Value: Fast response and low dynamic impedance ensure <100 ns clamping onset - preventing latch-up in isolated RS-485 transceivers and microcontrollers. |
| Switching Power Supply Output Crowbar | Sensor Signal Line ESD Protection |
Use Scenario: Replacing SCR-based crowbar circuits in telecom rectifiers and server PSUs to avoid destructive short-circuit shutdown. IC Role / Device Role / Timing Role: Voltage-triggered shunt device across regulated output, conducting only during overvoltage events exceeding VBR. Use Value: Enables non-destructive overvoltage handling: clamps instead of shorting, allowing fuse/breaker coordination and system recovery without component replacement. | Use Scenario: Protecting analog front-end inputs of automotive pressure/temperature sensors from ESD (IEC 61000-4-2 ±15 kV contact) and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF at VWM) unidirectional clamp on signal line referenced to local ground. Use Value: Maintains signal integrity up to 1 MHz due to minimal junction capacitance - avoids filtering distortion in 0–5 V sensor outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-E3/52 | Lower peak power (600 W), SMC package, same VWM (54 V), higher VC (87.1 V → 93.6 V) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when board space is constrained and surge energy is ≤600 W - not suitable for automotive load dump. |
| 1.5KE56A | Same P600 package, 56 V VWM, but only 1500 W PPPM; no AEC-Q101 or HE3 whisker rating | Legacy part with obsolete packaging; lacks automotive qualification and modern whisker mitigation | Use only for cost-sensitive, non-automotive designs where 1500 W surge margin suffices and long-term supply continuity is assured. |
Compared with SMBJ54A-E3/52 and 1.5KE56A, the 5KP15HE3/54 delivers 3.3× higher pulse power handling, certified automotive reliability, and enhanced long-term interconnect stability - making it the sole choice for safety-critical 48 V systems requiring ISO 16750 compliance and 15+ year field life.

FAQ
What is the breakdown voltage range of the 5KP15HE3/54?
The 5KP15HE3/54 has a specified breakdown voltage (VBR) range of 60.0 V to 66.3 V at a test current of 5.0 mA, per JEDEC-registered data in the Vishay datasheet (Doc. #88308). This 5% tolerance ensures consistent clamping behavior across production lots and supports reliable coordination with 54 V system rails.
Is the 5KP15HE3/54 suitable for automotive applications?
Yes, the 5KP15HE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance plus JESD 201 Class 2 whisker resistance - both required for automotive under-hood and powertrain applications. Its 175 °C max junction temperature and validated thermal performance per Fig. 2 and Fig. 5 further confirm suitability for automotive environments.
What does the "HE3" suffix mean in 5KP15HE3/54?
The "HE3" suffix in 5KP15HE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - distinguishing it from the commercial-grade "E3" variant. This suffix confirms compliance with automotive reliability standards and long-term solder joint integrity under thermal cycling and humidity stress.
How does the 5KP15HE3/54 compare to standard 1.5 kW TVS diodes like 1.5KE56A?
The 5KP15HE3/54 provides 5000 W peak pulse power - over three times the 1500 W rating of 1.5KE56A - while maintaining the same P600 package footprint. It also adds AEC-Q101 qualification, HE3 whisker resistance, and tighter VBR tolerance, making it a direct upgrade for demanding automotive and industrial surge protection where legacy parts fall short.
What is the maximum clamping voltage of the 5KP15HE3/54 at rated peak current?
The maximum clamping voltage (VC) of the 5KP15HE3/54 is 87.1 V at its rated peak pulse current (IPPM) of 57.4 A, measured with a 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet (Doc. #88308, Table on page 2) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
