Product details
Overview
5KP24HE3/54 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), 24.0 V stand-off voltage (VWM), and 38.9 V maximum clamping voltage (VC) at 129 A peak pulse current. It protects MOSFETs and ICs in automotive power supplies against inductive switching transients.
For engineers reviewing the 5KP24HE3/54 datasheet, 5KP24HE3/54 pinout, 5KP24HE3/54 application, or 5KP24HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low incremental surge resistance, and RoHS-compliant matte tin-plated leads suitable for high-reliability industrial and automotive designs.
Technical Context
The 5KP24HE3/54 uses a glass-passivated P600 chip junction optimized for fast response to sub-microsecond transients. Its unidirectional polarity enables integration into DC power rails where reverse conduction must be blocked, and its 175 °C maximum junction temperature supports operation in under-hood automotive environments.
Designed for crowbar-circuit replacement in switching power supply outputs, it sustains 5000 W peak pulse power without degradation when mounted on adequate heatsinking. The device's 0.101 %/°C breakdown voltage temperature coefficient ensures stable clamping across wide thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 24.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin. |
| VBR (Breakdown Voltage) | 26.7–29.5 V at 5.0 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 38.9 V at 129 A (10/1000 μs) - Limits downstream component stress to safe levels during surge conditions. |
| PPPM (Peak Pulse Power) | 5000 W - Sustains high-energy transients typical of automotive load-dump or inductive kickback. |
| IPPM (Peak Pulse Current) | 129 A - Validated surge current handling capacity with JEDEC-standard 10/1000 μs waveform. |
| TJ max. | 175 °C - Enables use in high-temperature engine-control units and industrial motor drives. |
| Polarity | Unidirectional - Blocks reverse current flow; required for DC bus protection where polarity is fixed. |
Pinout & Package
Package: P600 molded epoxy case with UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to system ground or low-side return path in unidirectional TVS configuration. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 24 V rail); clamps to VC when voltage exceeds VBR. |
Key Features
| Feature | Design Value |

| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker test and automotive material compliance requirements (doc. 99912). |
| Fast response time | Sub-nanosecond turn-on enables suppression before transient energy damages downstream MOSFETs or controllers. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load-dump transients up to 60 V during alternator regulation failure. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed directly across input terminals of DC-DC converters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24AHE3/52 | Lower peak power (600 W), smaller SMB package, same VWM/VC but higher dynamic impedance. | Suitable for lower-energy surges (IEC 61000-4-2 ESD only); not rated for load-dump or 5000 W pulses. | Select when board space is constrained and surge threat level is limited to ESD or low-energy coupling. |
| 1.5KE24A | Same VWM (24 V) and PPPM (5000 W), but TO-204AE (DO-3) package and non-AEC-Q101 qualified. | Lacks automotive qualification; requires external validation for under-hood use; lead finish differs (no JESD 201 Class 2 whisker rating). | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated and legacy DO-3 footprint is preferred. |
Compared with SMBJ24AHE3/52 and 1.5KE24A, the 5KP24HE3/54 uniquely combines AEC-Q101 qualification, P600 thermal robustness for 5000 W dissipation, and JESD 201 Class 2 whisker resistance-making it the only option qualified for high-energy automotive load-dump protection without derating or secondary thermal management.

FAQ
What is the clamping voltage of the 5KP24HE3/54 under standard test conditions?
The 5KP24HE3/54 has a maximum clamping voltage (VC) of 38.9 V at 129 A peak pulse current using the industry-standard 10/1000 μs waveform. This value is measured per JEDEC test methods and guarantees predictable overvoltage limiting during surge events. The 5KP24HE3/54 maintains this clamping performance across its full operating temperature range and after repeated transient exposure, provided thermal design guidelines are followed.
Is the 5KP24HE3/54 suitable for automotive applications?
Yes, the 5KP24HE3/54 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS power domains. Its P600 package provides superior thermal dissipation for load-dump events, and the HE3 suffix confirms compliance with JESD 201 Class 2 whisker testing. The 5KP24HE3/54 meets all electrical and mechanical requirements for under-hood deployment per Vishay's qualification report (doc. 88308).
How does the 5KP24HE3/54 differ from the 5KP24A-E3/54 variant?
The 5KP24HE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, whereas the 5KP24A-E3/54 is commercial-grade (Class 1A whisker test). Both share identical electrical specs (VWM, VBR, VC, PPPM), but only the 5KP24HE3/54 is approved for automotive production. The 5KP24HE3/54 also carries stricter material compliance documentation per Vishay doc. 99912, making it the required choice for OEM-tier automotive designs.
What is the maximum operating temperature for the 5KP24HE3/54?
The 5KP24HE3/54 has a maximum junction temperature (TJ) of +175 °C and an operating storage range of –55 °C to +175 °C. This rating allows direct use in high-temperature environments such as engine compartments or industrial motor drive cabinets without derating, provided PCB copper area and airflow meet Vishay's P600 thermal guidelines in Figure 5 of document 88308. The 5KP24HE3/54 retains full 5000 W pulse capability up to TJ = 125 °C.
Can the 5KP24HE3/54 replace a 1.5KE24A in an existing design?
The 5KP24HE3/54 shares the same VWM (24 V), VBR (26.7–29.5 V), and PPPM (5000 W) as the 1.5KE24A, but uses a P600 package instead of TO-204AE (DO-3). While electrically compatible, the 5KP24HE3/54 requires PCB layout revision due to different footprint and lead spacing. The 5KP24HE3/54 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-critical upgrades if targeting automotive or long-lifecycle industrial use.
