Product details
Overview
5KP64AHE3_A/C 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 5000 W peak pulse power (10/1000 μs), 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR), 103 V clamping voltage at 48.5 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP64AHE3_A/C datasheet, 5KP64AHE3_A/C pinout, 5KP64AHE3_A/C application, or 5KP64AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs surges, thermal derating above 25 °C, unidirectional polarity requirement, P600 mechanical compatibility, and compliance with automotive transients per ISO 7637-2.
Technical Context
This TVS diode uses a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance to limit overvoltage during lightning or inductive switching events. Its unidirectional configuration provides reverse-biased clamping only, with forward conduction limited to 3.5 V at 100 A.
The device operates across -55 °C to +175 °C junction temperature range and is rated for 500 A non-repetitive forward surge (8.3 ms half-sine). Derating curves confirm 5000 W peak pulse power is valid only at TA = 25 °C, dropping to ~3.2 kW at 100 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - Maximum continuous reverse operating voltage before leakage exceeds 2 μA; defines safe DC rail margin. |
| VBR min/max | 71.1 V / 78.6 V at 5 mA - Confirmed breakdown threshold range; ensures consistent clamping onset across production lot. |
| VC @ IPPM | 103 V at 48.5 A - Clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient stress. |
| PPPM | 5000 W - Peak pulse power handling capability; enables protection against severe lightning-induced surges (IEC 61000-4-5 Level 4). |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments with minimal heatsinking. |
| Polarity | Unidirectional - Cathode-marked device; suitable for DC supply line protection where reverse polarity is not expected. |
| Qualification | AEC-Q101 - Validated for automotive electronics; includes stress testing for temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 9.5 mm body length; lead spacing 8.6 mm; RoHS compliant (HE3 suffix denotes AEC-Q101 qualification).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

|---|---|
|
Use Scenario: Protection of 64 V battery-fed control modules (e.g., ADAS ECUs, lighting drivers) against load dump and jump-start transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and input filter capacitor; activates within nanoseconds upon overvoltage detection. Use Value: Limits transient voltage to 103 V, preventing damage to 75 V-rated DC-DC controllers and CAN transceivers downstream. |
Use Scenario: Input-stage surge suppression in 48–72 V industrial PLC power supplies exposed to motor drive noise and field wiring transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on bulk input rail; coordinates with upstream fuse to allow controlled fault clearing without system shutdown. Use Value: Withstands 5000 W pulses while maintaining <2 μA leakage at 64 V, minimizing standby power loss in always-on systems. |
| Telecom Base Station Power | Renewable Energy Inverters |
|
Use Scenario: DC input protection for 48 V telecom rectifiers subjected to lightning-induced surges on outdoor feeder lines. IC Role / Device Role / Timing Role: High-power TVS mounted directly at chassis entry point; shunts surge energy to earth ground before reaching sensitive AC/DC converters. Use Value: 175 °C max junction temperature allows operation in sealed enclosures with minimal airflow, reducing need for forced cooling. |
Use Scenario: Surge protection on PV string combiner box inputs (64 V nominal) exposed to induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between PV+ and ground; clamps common-mode transients exceeding 64 V without false triggering. Use Value: AEC-Q101 qualification ensures long-term stability under thermal cycling from desert daytime/nighttime swings. |
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 (Vishay) | Lower peak power (600 W), SMC package, same VWM/VC but higher clamping ratio (104 V @ 5.9 A) | Best suited for space-constrained PCBs with moderate surge exposure (IEC 61000-4-5 Level 2) | Select when board area is critical and surge energy is below 100 mJ; not suitable for load dump or lightning-level threats. |
| 1.5KE68A (ON Semiconductor) | Same P600 package, 68 V VWM, 5000 W rating, but no AEC-Q101 qualification and higher VC (118 V @ 42.4 A) | Acceptable for commercial/industrial use where automotive qualification is not required | Choose for cost-sensitive non-automotive designs where 118 V clamping is acceptable and AEC-Q101 is unnecessary. |
Compared with SMBJ64A-E3/52, 5KP64AHE3_A/C delivers >8× higher surge energy handling in identical mounting footprint; versus 1.5KE68A, it offers tighter clamping (103 V vs. 118 V) and guaranteed automotive qualification-critical for safety-critical vehicle subsystems.

FAQ
What is the clamping voltage of the 5KP64AHE3_A/C and how is it measured?
The 5KP64AHE3_A/C has a maximum clamping voltage (VC) of 103 V, measured at its rated peak pulse current (IPPM) of 48.5 A using a 10/1000 μs waveform. This value is guaranteed across production lots and represents the highest voltage seen across the device terminals during standardized surge testing. The 5KP64AHE3_A/C maintains this clamping performance up to its maximum junction temperature of +175 °C, with minor derating above 25 °C ambient.
Is the 5KP64AHE3_A/C suitable for bidirectional transient protection?
No, the 5KP64AHE3_A/C is unidirectional only, with a cathode band marking the high-side terminal. It clamps reverse-biased transients but conducts forward current like a standard diode above ~3.5 V. For bidirectional protection (e.g., AC lines or data buses), a separate 5KP64CA variant or back-to-back unidirectional configuration is required. The 5KP64AHE3_A/C datasheet explicitly states "Available in unidirectional polarity only" and does not specify symmetrical breakdown behavior.
How does the AEC-Q101 qualification impact the use of 5KP64AHE3_A/C in automotive designs?
The AEC-Q101 qualification confirms that the 5KP64AHE3_A/C has passed accelerated stress tests including temperature cycling, high-temperature reverse bias, and ESD, making it suitable for automotive powertrain and chassis applications. This qualification is mandatory for components used in systems subject to ISO/TS 16949 and supports long-term reliability in under-hood environments where thermal cycling and vibration are present. The 5KP64AHE3_A/C HE3 suffix explicitly denotes this qualification level.
What is the maximum allowable lead temperature during soldering for the 5KP64AHE3_A/C?
The 5KP64AHE3_A/C supports solder dip at a maximum temperature of 275 °C for up to 10 seconds, per JESD 22-B106. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability. Reflow profiles must stay within JEDEC J-STD-020 limits for P600 packages, with peak temperatures not exceeding 260 °C for ≤30 seconds. Exceeding these limits risks epoxy cracking or junction degradation, which would compromise the 5KP64AHE3_A/C's surge performance.
Can the 5KP64AHE3_A/C replace a 5KP60A in an existing design?
Yes, the 5KP64AHE3_A/C can replace 5KP60A with careful validation: both share identical P600 package, AEC-Q101 qualification, and 5000 W rating, but VWM increases from 60 V to 64 V and VC rises from 97.0 V to 103 V. This shift may reduce margin for downstream 75 V-rated components. Review system-level transient tolerance and ensure the higher clamping voltage remains within safe operating limits before substituting 5KP64AHE3_A/C for 5KP60A.
