Product details
Overview
5KP75HE3/73 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 75 V stand-off voltage (VWM), 83.3–92.1 V breakdown voltage (VBR at 5.0 mA), 5000 W peak pulse power (10/1000 µs), clamping voltage of 121 V at 41.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP75HE3/73 datasheet, 5KP75HE3/73 pinout, 5KP75HE3/73 application, or 5KP75HE3/73 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, automotive ECUs, industrial motor drives, and sensor interface circuits where fast response (<1 ns), low clamping ratio, and high surge current handling are critical.
Technical Context
This TVS operates as a voltage-clamping avalanche diode with glass-passivated P600 junction, optimized for non-repetitive transients induced by inductive load switching or lightning surges. Its unidirectional polarity enables integration into DC-biased lines without reverse conduction concerns, and its 175 °C maximum junction temperature supports operation in under-hood automotive environments.
The device delivers 41.3 A peak pulse current (IPPM) at 121 V clamping voltage under 10/1000 µs waveform, with <2.0 µA leakage at 75 V and 0.108 %/°C VBR temperature coefficient - enabling stable clamping across wide thermal ranges without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V/24 V/48 V systems. |
| VBR (min/max) | 83.3 V / 92.1 V at 5.0 mA - Confirmed breakdown range ensures predictable turn-on threshold with ±5 % tolerance. |
| IPPM | 41.3 A - Peak surge current it safely shunts during 10/1000 µs transient, enabling coordination with downstream fuses/circuit breakers. |
| VC | 121 V - Clamped voltage at IPPM; limits stress on protected ICs (e.g., MCU I/O, gate drivers) to survivable levels. |
| PPPM | 5000 W - Peak pulse power rating confirms suitability for high-energy threats like ISO 7637-2 Pulse 5a (load dump). |
| TJ max | 175 °C - Enables direct mounting on PCBs near heat-generating components in automotive engine control units. |
| AEC-Q101 | Qualified - Validated for automotive applications including ECU, body control modules, and ADAS sensor interfaces. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, UL 94 V-0 rated; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side (e.g., ground or return line) in unidirectional configuration. |
| Cathode | Clamping node | Connected to protected line (e.g., 24 V rail); conducts avalanche current when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables protection against severe automotive load dump events without derating or parallel devices. |
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per JESD47. |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage overshoot during surge, reducing risk of latch-up or damage to downstream MOSFETs/ICs. |
| Fast response time (<1 ns) | Activates before sensitive circuitry experiences damaging voltage rise, critical for protecting high-speed sensor interfaces. |
| 175 °C junction rating | Supports placement near power converters or motors without thermal derating in compact industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Lower peak power (600 W), smaller SMB package, same 75 V VWM, higher VC (123 V at 4.3 A) | Suitable for board space-constrained consumer electronics but insufficient for automotive load dump per ISO 7637-2. | Select SMBJ75A only for low-energy surges (e.g., IEC 61000-4-2 ESD) where PCB area is critical and 5000 W capability is unnecessary. |
| 1.5KE75A | Same 75 V VWM, but lower PPPM (1500 W), DO-201 package, higher VC (120 V at 12.5 A), no AEC-Q101 qualification | Acceptable for industrial controls with moderate surge exposure, but not validated for automotive temperature/humidity cycles. | Choose 1.5KE75A for cost-sensitive non-automotive designs where 1500 W peak power meets system-level test requirements. |
Compared with SMBJ75A and 1.5KE75A, the 5KP75HE3/73 uniquely combines 5000 W surge capacity, AEC-Q101 qualification, and P600 thermal mass - making it the only option among the three capable of surviving repeated load dump events in automotive power distribution modules.

FAQ
What is the clamping voltage of the 5KP75HE3/73 under peak surge conditions?
The 5KP75HE3/73 has a maximum clamping voltage (VC) of 121 V at 41.3 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures protected circuitry remains below critical overvoltage thresholds during transient events such as ISO 7637-2 Pulse 5a. The 5KP75HE3/73 maintains this clamping performance across its full operating temperature range.
Is the 5KP75HE3/73 suitable for automotive applications?
Yes, the 5KP75HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and validation against temperature cycling, humidity, and mechanical shock make it appropriate for engine control units, body electronics, and ADAS sensor power rails. The 5KP75HE3/73 meets key automotive surge immunity standards including ISO 7637-2.
How does the 5KP75HE3/73 differ from the standard 5KP75A variant?
The 5KP75HE3/73 differs from the base 5KP75A by its HE3 suffix, indicating AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and RoHS compliance. The "H" denotes automotive qualification, "E3" confirms RoHS and lead-free plating, and "/73" specifies packaging in 73 mm tape-and-reel format. Electrically, both share identical VWM, VBR, and PPPM ratings - the distinction is in reliability testing and process control.
What is the maximum leakage current of the 5KP75HE3/73 at its stand-off voltage?
The 5KP75HE3/73 exhibits a maximum reverse leakage current (ID) of 2.0 µA at its 75 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. Leakage remains within specification up to 125 °C, supporting reliable operation in thermally demanding applications.
Can the 5KP75HE3/73 be used in bidirectional configurations?
No, the 5KP75HE3/73 is unidirectional only, with polarity marked by a cathode band. It conducts avalanche current only when the cathode is positive relative to the anode. For AC or bidirectional transient protection, a separate back-to-back pair or a dedicated bidirectional TVS (e.g., 5KP75CA) must be used. Using the 5KP75HE3/73 in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
