Product details
Overview
5KP64HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 5000 W peak pulse power (10/1000 μs), 64 V stand-off voltage (VWM), and 87.1 V maximum clamping voltage (VC) at 57.4 A peak pulse current. It protects MOSFETs and ICs in automotive power supplies against inductive switching surges.
For engineers reviewing the 5KP64HE3/54 datasheet, 5KP64HE3/54 pinout, 5KP64HE3/54 application, or 5KP64HE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant matte tin leads, and P600 package compatibility with high-energy surge environments.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown above its 64 V stand-off threshold. Its 5000 W peak pulse rating and low incremental surge resistance enable robust suppression of 10/1000 μs transients without thermal runaway.
Designed for automotive-grade reliability, the 5KP64HE3/54 features AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molded epoxy body. It sustains 600 A non-repetitive forward surge current and maintains stable clamping performance across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below circuit rail. |
| VBR min/max | 71.1 V / 78.6 V - Breakdown voltage range at 50 mA test current; ensures reliable turn-on within tolerance band. |
| VC @ IPPM | 87.1 V - Clamped voltage at 57.4 A peak pulse; determines maximum stress on protected downstream components. |
| PPPM | 5000 W - Peak pulse power handling with 10/1000 μs waveform; supports high-energy surge immunity per ISO 7637-2. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-band marked; suitable only for DC-biased or single-polarity surge paths. |
| Package | P600 - Axial-leaded, 9.5 mm body length; provides mechanical robustness and thermal mass for surge dissipation. |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with cathode band marking; lead finish is matte tin, solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection in unidirectional configuration | Connected to ground or low-voltage reference; completes clamping path during overvoltage events. |
| Cathode | High-side connection with color band marking | Connected to protected line (e.g., 64 V rail); avalanche conduction initiates when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring long-term reliability under thermal cycling and vibration. |
| 5000 W peak pulse power | Withstands high-energy transients such as load dump (ISO 7637-2 Pulse 5a) without failure or parameter shift. |
| Low clamping ratio (VC/VBR ≈ 1.11) | Minimizes overvoltage overshoot during clamping, reducing stress on protected MOSFET gate oxides and IC input structures. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high humidity and temperature bias, critical for long-life automotive modules. |
| UL 94 V-0 molding compound | Self-extinguishing epoxy prevents flame propagation in enclosed automotive enclosures during fault conditions. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 64 V battery-fed ECUs against load dump transients up to 120 V. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed across input rail to shunt surge energy to ground before upstream regulator or MCU is damaged. Use Value: Limits peak rail voltage to ≤87.1 V during 5000 W pulses, preserving 100 V-rated input capacitors and enabling fuse coordination. | Use Scenario: Safeguarding IGBT gate drivers on 60–70 V DC bus in servo amplifiers. IC Role / Device Role / Timing Role: Fast-response clamping element suppressing inductive kickback from motor winding commutation. Use Value: Sub-1 ns response time prevents gate oxide rupture; 175 °C rating supports operation near heatsinks. |
| Telecom DC Feeder Line | Renewable Energy Charge Controller |
Use Scenario: Surge protection on 48–60 V telecom remote radio head power feeds exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on outdoor-rated DC input stage. Use Value: 5000 W rating handles multiple 10/1000 μs surges; RoHS-compliant matte tin leads ensure corrosion resistance in humid coastal deployments. | Use Scenario: Input protection for solar charge controllers interfacing with 64 V nominal battery banks. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing PV array voltage spikes during cloud-edge transitions or disconnect events. Use Value: 64 V VWM aligns with battery float voltage; 87.1 V VC stays below controller's absolute maximum input rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | Lower peak power (600 W), smaller SMB package, same 64 V VWM, higher VC (103 V) | Not suitable for load dump; limited to board-level ESD and low-energy transients | Select when space-constrained and surge energy < 100 mJ; not AEC-Q101 qualified. |
| 1.5KE68A | Same P600 package, 68 V VWM, 5000 W rating, but no AEC-Q101 qualification or JESD 201 Class 2 whisker rating | Lacks automotive qualification; requires additional reliability validation for vehicle programs | Select for industrial-only use where AEC-Q101 is not mandated; identical thermal and electrical footprint. |
Compared with SMBJ64A-E3/52 and 1.5KE68A, the 5KP64HE3/54 uniquely combines AEC-Q101 qualification, 5000 W capability, and JESD 201 Class 2 whisker resistance in a single P600 package-making it the only drop-in solution for production automotive 64 V systems requiring zero reliability requalification.

FAQ
What is the clamping voltage of the 5KP64HE3/54 under peak pulse conditions?
The 5KP64HE3/54 has a maximum clamping voltage (VC) of 87.1 V at its rated peak pulse current (IPPM) of 57.4 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures downstream components see no more than 87.1 V during worst-case surge events, directly supporting design margin calculations for 100 V-rated devices.
Is the 5KP64HE3/54 qualified for automotive applications?
Yes, the 5KP64HE3/54 carries AEC-Q101 qualification, confirmed in Vishay's official documentation (Document Number: 88308, Revision: 20-Nov-12). It also meets JESD 201 Class 2 whisker resistance and operates across -55 °C to +175 °C, making it suitable for under-hood ECU, body control module, and ADAS power rail protection.
What does the "HE3" suffix indicate in 5KP64HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "E3" base indicates matte tin plating meeting J-STD-002 solderability, while "H" explicitly signals automotive qualification-distinct from commercial-grade "E3" variants like 5KP64A-E3/54.
Can the 5KP64HE3/54 be used in bidirectional signal line protection?
No, the 5KP64HE3/54 is unidirectional only, with cathode-band polarity marking. It must be installed with cathode toward the protected line and anode to ground. For bidirectional protection (e.g., data lines), a separate symmetric TVS array or dual-diode configuration is required-this part cannot be repurposed for AC or differential signaling paths.
What is the thermal derating behavior of the 5KP64HE3/54 above 25 °C ambient?
The 5KP64HE3/54 follows standard JEDEC thermal derating: its peak pulse power (5000 W) is fully rated at TA = 25 °C, then linearly derates to zero at TJ = 175 °C. Derating curves (Fig. 2 in Document 88308) show ~75 % power capability at 75 °C ambient with proper heatsinking, critical for under-hood placement where ambient may exceed 85 °C.
