Product details
Overview
5KP30HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping in power supply outputs and automotive electronics. It features 30 V stand-off voltage (VWM), 33.3–36.8 V breakdown voltage (VBR) at 50 mA, 48.4 V maximum clamping voltage (VC) at 103 A peak pulse current, and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and RoHS compliant.
For engineers reviewing the 5KP30HE3/73 datasheet, 5KP30HE3/73 pinout, 5KP30HE3/73 application, or 5KP30HE3/73 equivalent, this device is selected for robust overvoltage protection in DC power rails where fast response (<1 ns), low clamping ratio, and high single-pulse energy handling are required - especially in automotive ECUs, industrial SMPS outputs, and battery-fed systems subject to load dump or inductive switching transients.
Technical Context
The 5KP30HE3/73 employs a glass-passivated P600 chip junction optimized for uni-directional surge suppression. Its clamping behavior is defined by a tightly controlled VBR range (33.3–36.8 V) and low incremental surge resistance, enabling predictable voltage limiting during 10/1000 μs transients up to 5000 W. It operates across –55 °C to +175 °C junction temperature with 0.103 %/°C VBR temperature coefficient.
This TVS diode is rated for 103 A peak pulse current (IPPM) and 600 A non-repetitive forward surge current (IFSM), with 3.5 V instantaneous forward voltage at 100 A. Its 8.0 W steady-state power dissipation (PD) on infinite heatsink and 2.0 μA max reverse leakage at 30 V support reliable long-term operation in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous reverse operating voltage before clamping begins; sets safe DC rail margin for 30 V nominal systems. |
| VBR (min/max) | 33.3 V / 36.8 V at 50 mA - Confirmed breakdown threshold range; ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 48.4 V at 103 A - Clamped voltage under full-rated 10/1000 μs surge; defines worst-case overvoltage seen by downstream circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ30A | Lower peak power (400 W), SMA package (surface-mount), 43.5 V clamping at 9.8 A. | Targeted at PCB space-constrained consumer electronics; insufficient for automotive load dump. | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 3. |
| ON Semiconductor 1.5KE30A | Same P600 package, 30 V VWM, but lower PPPM (1500 W), 49.9 V clamping at 30.1 A. | Suitable for general-purpose industrial protection but not AEC-Q101 qualified. | Choose for cost-sensitive non-automotive designs where 1500 W surge capability meets system requirements. |
Compared with SMAJ30A and 1.5KE30A, the 5KP30HE3/73 delivers 3.3× higher peak power than 1.5KE30A and >12× more than SMAJ30A, while providing AEC-Q101 validation and tighter VBR tolerance - making it the only option among the three qualified for automotive under-hood deployment.

FAQ
What is the clamping voltage of the 5KP30HE3/73 under maximum rated surge current?
The 5KP30HE3/73 has a maximum clamping voltage (VC) of 48.4 V when subjected to its rated 103 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured and guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 5KP30HE3/73 suitable for automotive applications?
Yes, the 5KP30HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction, testing, and performance parameters-including 175 °C max junction temperature, P600 package robustness, and load dump surge capability-meet requirements for engine control units, body electronics, and ADAS power inputs.
How does the HE3 suffix differ from the E3 suffix in the 5KP30HE3/73 part number?
The HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only (JESD 201 Class 1A). The 5KP30HE3/73 is therefore validated for automotive reliability, while 5KP30A-E3/73 is intended for non-automotive industrial or consumer use.
What is the maximum reverse leakage current of the 5KP30HE3/73 at its stand-off voltage?
The 5KP30HE3/73 exhibits a maximum reverse leakage current (ID) of 2.0 μA at its 30 V stand-off voltage (VWM), measured at 25 °C. This low leakage ensures minimal power loss in always-on systems such as automotive always-live circuits or telecom remote power feeds.
Can the 5KP30HE3/73 replace older 1.5KE-series TVS diodes in existing designs?
The 5KP30HE3/73 is not a direct drop-in replacement for 1.5KE30A due to higher peak pulse power (5000 W vs. 1500 W), different clamping characteristics, and AEC-Q101 qualification. Layout changes may be needed to accommodate thermal dissipation, and system-level surge testing is required to validate performance equivalence in the target application.
