Product details
Overview
5KP100HE3/54 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 100 V stand-off voltage (VWM), 162 V maximum clamping voltage (VC) at 30.9 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform), with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP100HE3/54 datasheet, 5KP100HE3/54 pinout, 5KP100HE3/54 application, or 5KP100HE3/54 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, motor drive circuits, and automotive electronic control units where fast clamping response (<1 ns), low incremental surge resistance, and repeatable 0.01% duty cycle surge handling are critical.
Technical Context
The 5KP100HE3/54 uses a glass-passivated P600 chip junction optimized for high peak pulse power dissipation without thermal runaway. Its unidirectional polarity enables integration into DC-biased rail protection schemes where reverse conduction must be blocked until breakdown threshold is exceeded.
Clamping performance is defined by a tightly controlled 111–123 V breakdown voltage range (VBR) at 5.0 mA test current, with <0.110 %/°C temperature coefficient ensuring stable protection thresholds across –55 °C to +175 °C operating junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 111–123 V at 5.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 162 V at 30.9 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 5000 W - Sustains single high-energy surges per JEDEC standard; enables replacement of crowbar circuits in PSU outputs. |
| TJ max. | +175 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Polarity | Unidirectional - Blocks reverse current until breakdown; suited for DC rail protection with defined bias direction. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress-test requirements including HTGB, HTRB, and temperature cycling. |
Pinout & Package
5KP100HE3/54 is housed in a P600 molded epoxy package with axial leads. The cathode is marked by a color band on the body; the anode and cathode terminals are non-polarized in layout but functionally asymmetric due to unidirectional avalanche behavior.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side reference terminal | Connected to ground or low-voltage rail; completes conduction path during reverse-biased avalanche. |
| Cathode (banded end) | High-side surge input terminal | Connected to protected line (e.g., 12 V battery rail); absorbs transient energy when voltage exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-event suppression of lightning-induced surges up to IEC 61000-4-5 Level 4 (4 kV/2 Ω) without failure. |
| 162 V clamping at 30.9 A | Keeps protected MOSFET gate drivers and microcontroller I/O pins within absolute maximum ratings during 100 A-equivalent system-level transients. |
| AEC-Q101 qualification | Validates reliability for automotive ECU, body control module, and ADAS sensor interface applications requiring zero field failures. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed power systems, meeting safety standards for industrial and transportation equipment. |
| Matte tin-plated leads (J-STD-002 compliant) | Ensures consistent solder wetting and intermetallic formation in reflow and wave soldering processes for high-yield manufacturing. |
Applications
| Automotive Power Rail Protection | Industrial Switching Power Supply Output |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump transients (ISO 16750-2, up to 120 V/100 ms). IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and regulator input to clamp overvoltage before LDO or DC/DC converter. Use Value: Clamps to ≤162 V within nanoseconds, preventing damage to automotive-grade microcontrollers and CAN transceivers rated for 40 V absolute max. |
Use Scenario: Safeguarding 48 V telecom rectifier outputs from inductive switching spikes generated by relay banks or fan controllers. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, coordinated with upstream fusing to allow resettable fault recovery. Use Value: Withstands 5000 W pulses without degradation, enabling elimination of crowbar SCR circuits and reducing BOM count and board space. |
| Motor Drive DC Bus Protection | Telecom Line Card Surge Suppression |
Use Scenario: Absorbing regenerative energy spikes from brushed DC motors in factory automation actuators during rapid deceleration. IC Role / Device Role / Timing Role: Parallel-connected TVS across H-bridge DC link capacitor to limit bus overvoltage during dynamic braking. Use Value: Low incremental surge resistance minimizes voltage overshoot during 30.9 A transient events, preserving IGBT gate oxide integrity. |
Use Scenario: Protecting Ethernet PHY interfaces and PoE injectors from induced surges on long copper runs in building infrastructure. IC Role / Device Role / Timing Role: Secondary-stage TVS after gas discharge tube (GDT) front-end, providing precise clamping for sensitive silicon. Use Value: 100 V VWM allows placement after GDT coordination while maintaining margin above 57 V PoE+ nominal; 162 V VC prevents PHY latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHE3/52 | Lower peak power (600 W), smaller SMB package, same 100 V VWM and unidirectional polarity. | Suitable for lower-energy transients (IEC 61000-4-2 contact discharge only); not rated for load dump or high-current inductive spikes. | Select when board space is constrained and surge threat level is limited to ESD or low-energy switching noise. |
| 1.5KE100A | Same 100 V VWM and P600 package, but 1500 W peak power and no AEC-Q101 qualification. | Lacks automotive qualification and derating validation for extended temperature cycling; higher clamping voltage (165 V) at rated current. | Choose for cost-sensitive industrial controls where AEC-Q101 is not mandated and 1500 W suffices. |
Compared with SMBJ100AHE3/52 and 1.5KE100A, the 5KP100HE3/54 delivers 3.3× higher peak power and automotive qualification-critical for protecting high-reliability power rails where sustained 5000 W surges must be absorbed without parameter shift or failure.

FAQ
What is the clamping voltage of the 5KP100HE3/54 under standard test conditions?
The 5KP100HE3/54 has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 30.9 A using the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees the voltage imposed on protected circuitry remains within safe limits during surge events.
Is the 5KP100HE3/54 suitable for automotive applications?
Yes, the 5KP100HE3/54 carries AEC-Q101 qualification, confirming it meets stress-test requirements for automotive electronics-including high-temperature reverse bias, temperature cycling, and humidity testing. Its 175 °C max junction temperature and robust P600 package make it appropriate for under-hood and ECU use.
What does the "HE3" suffix indicate in 5KP100HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms enhanced reliability for automotive and demanding industrial deployments.
How does the 5KP100HE3/54 differ from the 1.5KE100A in practical design use?
The 5KP100HE3/54 provides 5000 W peak pulse power versus 1500 W for the 1.5KE100A, enabling protection against higher-energy transients like ISO 16750-2 load dump. It also includes AEC-Q101 qualification and tighter clamping (162 V vs. 165 V), making it preferable for automotive and mission-critical industrial systems.
Can the 5KP100HE3/54 be used in bidirectional signal line protection?
No-the 5KP100HE3/54 is unidirectional only, with cathode marked by a band. For bidirectional signal line protection (e.g., RS-485, USB), a symmetric TVS array or dedicated bidirectional part such as SMAJ100A must be used instead of the 5KP100HE3/54.
