Product details
Overview
5KP64HE3/73 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 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR at 5 mA), 103 V clamping voltage (VC) at 48.5 A peak pulse current, and 5000 W peak pulse power (10/1000 µs). It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor interfaces in automotive power supplies.
For engineers reviewing the 5KP64HE3/73 datasheet, 5KP64HE3/73 pinout, 5KP64HE3/73 application, or 5KP64HE3/73 equivalent, this page delivers verified electrical parameters, mechanical package data, clamping behavior under surge, AEC-Q101 qualification status, and direct alternative options for automotive-grade overvoltage protection design.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its breakdown threshold (VBR = 71.1–78.6 V), then limiting transient energy by shunting current to ground while maintaining clamped voltage ≤103 V at 48.5 A. Its P600 glass-passivated junction enables low incremental surge resistance and fast response (<1 ns).
Rated for 5000 W peak pulse power (10/1000 µs), it sustains 8.0 W steady-state dissipation on infinite heatsink at TL = 75 °C and handles 600 A non-repetitive forward surge (8.3 ms half-sine). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin. |
| VBR (min/max) | 71.1 V / 78.6 V at 5 mA - Breakdown onset range; determines precise clamping trigger point in production tolerance. |
| VC @ IPPM | 103 V at 48.5 A - Clamped voltage during 5000 W surge; must stay below protected device's absolute max rating. |
| PPPM | 5000 W (10/1000 µs) - Peak transient energy handling capacity; validates suitability for ISO 7637-2 Pulse 5a/b or IEC 61000-4-5 Level 4. |
| IFSM | 600 A (8.3 ms half-sine) - Surge current endurance without bond-wire failure; supports fuse-coordination in overcurrent events. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with thermal derating. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling. |
Pinout & Package
5KP64HE3/73 uses the axial-lead P600 package: molded epoxy body with matte tin-plated leads, cathode indicated by color band. Leads meet J-STD-002/JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance. Case complies with UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to protected circuit ground or low-side reference; carries full surge current during clamping. |
| Cathode | Reverse voltage sensing / Clamp output node | Connected to line being protected (e.g., +12 V rail); voltage referenced to anode during transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables robust protection against severe load-dump transients in 12 V/24 V automotive systems without cascading failure. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules requiring zero-defect field performance. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on downstream silicon-critical for protecting 75 V-rated MOSFETs or 65 V-input DC/DC controllers. |
| P600 glass-passivated junction | Delivers stable VBR and low leakage (<2 µA at VWM) across -55 °C to +175 °C operating range. |
| Uni-directional polarity | Suitable for DC-biased lines only; prevents unintended conduction during normal forward operation of power rails. |
Applications
| Automotive Load-Dump Protection | Industrial DC Power Rail Clamp |
|---|---|
Use Scenario: Suppresses 120 V/100 ms load-dump transients induced by alternator disconnection in vehicle battery systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between battery rail and ECU input stage. Use Value: Limits voltage to ≤103 V during 5000 W surge, preventing latch-up or gate oxide rupture in downstream PMICs and microcontrollers. |
Use Scenario: Protects 48 V telecom rectifier outputs from switching transients and lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across output terminals to absorb repetitive 10/1000 µs pulses. Use Value: Maintains system uptime by surviving >1000 surges without degradation, validated by AEC-Q101 HTRB testing. |
| Motor Drive Gate Driver Protection | Automotive Sensor Signal Line Guard |
Use Scenario: Shields high-side gate drivers in BLDC inverters from inductive kickback during MOSFET turn-off. IC Role / Device Role / Timing Role: Fast-response clamp placed between gate driver VDD and ground to limit supply rail overshoot. Use Value: Responds in <1 ns to clamp spikes before gate oxide breakdown occurs, preserving driver IC lifetime. |
Use Scenario: Guards LIN bus or analog sensor inputs (e.g., pressure, temperature) against ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-leakage (≤2 µA at 64 V) uni-directional TVS on signal line to chassis ground. Use Value: Prevents false triggering and offset drift in precision amplifiers by clamping transients while adding negligible DC loading. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64AHE3/52 | Lower peak power (600 W), SMC package, same VWM/VC but higher clamping ratio (110 V @ 5.5 A) | Targeted at board-level signal-line protection, not primary power rail clamping | Select when space-constrained layouts require surface-mount and surge energy is ≤600 W |
| 1.5KE68A-E3/54 | Same P600 package, lower peak power (1500 W), 68 V VWM, 118 V VC @ 12.7 A | Used in legacy industrial SMPS where 5000 W capability is unnecessary | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not required and surge levels are moderate |
Compared with 5KP64HE3/73, SMBJ64AHE3/52 offers compact SMT integration but sacrifices >80 % peak power handling; 1.5KE68A-E3/54 retains through-hole mounting yet lacks AEC-Q101 validation and clamping performance for demanding automotive load-dump scenarios.

FAQ
What is the clamping voltage of the 5KP64HE3/73 under maximum rated surge current?
The 5KP64HE3/73 clamps to 103 V at its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured per JEDEC standards and ensures protected components remain within safe operating voltage limits during worst-case transients. The 5KP64HE3/73 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C) with minimal derating.
Is the 5KP64HE3/73 suitable for bidirectional transient protection?
No, the 5KP64HE3/73 is a unidirectional TVS diode and must be used only on DC-biased lines where reverse polarity is defined. It conducts in forward bias like a standard diode and clamps only in reverse breakdown. For AC or bipolar signal lines, a bidirectional variant such as 5KP64CA would be required-not the 5KP64HE3/73.
Does the HE3 suffix on 5KP64HE3/73 indicate RoHS compliance and automotive qualification?
Yes, the HE3 suffix on 5KP64HE3/73 denotes both RoHS compliance and AEC-Q101 qualification. It also specifies JESD 201 Class 2 whisker resistance and matte tin plating meeting J-STD-002 solderability standards. These attributes are explicitly confirmed in Vishay document 88308 and distinguish it from commercial-grade E3 variants.
What is the maximum steady-state power dissipation for the 5KP64HE3/73?
The 5KP64HE3/73 has a maximum steady-state power dissipation (PD) of 8.0 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. This rating is derated linearly above 25 °C ambient and must be applied with appropriate thermal design-especially critical in enclosed automotive ECUs where junction temperature must remain ≤175 °C.
Can the 5KP64HE3/73 replace a 5KP60A in an existing design?
The 5KP64HE3/73 can replace 5KP60A only if the system's stand-off voltage margin allows 64 V vs. 60 V and clamping voltage increase (103 V vs. 97 V) does not exceed downstream component ratings. Both share identical P600 package, AEC-Q101 qualification, and 5000 W rating-but VWM, VBR, and VC differ per datasheet Table 1. Verify layout compatibility and transient margin before substitution.
