Product details
Overview
6KA24-E3/73 from Vishay General Semiconductor is an automotive-grade transient voltage suppressor (TVS) diode in P600 package, rated for 24 V working voltage, 6000 W peak pulse power (10/1000 µs), 90 A clamping current, 40 V max clamping voltage at 90 A, and AEC-Q101 qualified for load dump protection in 12 V automotive systems.
For engineers reviewing the 6KA24-E3/73 datasheet, 6KA24-E3/73 pinout, 6KA24-E3/73 application, or 6KA24-E3/73 equivalent, key selection criteria include clamping voltage at 90 A, 185 °C max junction temperature, RoHS-compliant matte tin leads, P600 mechanical robustness, and compliance with automotive surge standards including ISO 7637-2 and SAE J1128.
Technical Context
This TVS diode uses Vishay's patented PAR® construction to deliver low leakage (<1.0 µA at 24 V, 25 °C), high surge capability (400 A IFSM), and stable clamping performance across -65 °C to +185 °C operating range. Its unidirectional polarity (cathode marked by color band) supports DC rail protection in battery-connected circuits.
The device is optimized for single-pulse transients - not repetitive ESD - with two distinct pulse ratings: 6000 W (10/1000 µs) and 2000 W (10 µs/50 ms), reflecting different energy absorption profiles per IEC 61000-4-5 and automotive load dump waveforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous reverse operating voltage before breakdown; sets minimum system rail margin for 12 V automotive applications. |
| VC @ 90 A | 40 V (25 °C) - Clamping voltage during 90 A transient; defines maximum stress on downstream ICs during load dump events. |
| PPPM (10/1000 µs) | 6000 W - Peak pulse power handling for standard ISO 7637-2 load dump simulation; determines survivability under worst-case alternator surge. |
| TJ max. | +185 °C - Maximum junction temperature; enables operation in under-hood environments without derating below 150 °C ambient. |
| IRSM | 90 A - Rated peak pulse current for clamping specification; used with VC to calculate protected circuit voltage ceiling. |
| AEC-Q101 | Qualified - Certified for automotive use per stress test requirements including HTOL, TCT, and HAST; required for engine control, body electronics, and ADAS modules. |
| Leakage @ 24 V | 1.0 µA (25 °C) - Ultra-low reverse leakage ensures minimal standby power loss in always-on vehicle networks. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 0.360" × 0.340" footprint; 1.0" minimum lead length; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to chassis or system ground; forms low-impedance path for transient current return during clamping. |
| Cathode | Protected rail connection | Connected to +12 V battery line; absorbs positive-going transients via avalanche breakdown when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR® construction | Enables uniform voltage distribution across junction area, reducing localized thermal runaway risk during multi-kW surges. |
| High-temperature stability | Clamping voltage drift <12.5% from 25 °C to 150 °C (VC rises from 40 V to 45 V), ensuring predictable protection across full automotive thermal range. |
| Solder dip tolerance | Rated for 260 °C / 40 s immersion - compatible with lead-free reflow and selective soldering processes used in automotive PCB assembly. |
| JESD201 Class 2 whisker resistance | Matte tin plating meets whisker growth mitigation standard for long-term reliability in vibration-prone automotive harnesses and connectors. |
Applications
| Automotive Load Dump Protection | Engine Control Unit (ECU) Input Protection |
|---|---|
Use Scenario: Protects 12 V battery-fed circuits during alternator field-circuit disconnection, generating up to +120 V transients lasting 400 ms. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and ECU input filter stage; clamps voltage within safe limits before LDO or MCU input. Use Value: Limits peak voltage to ≤45 V at 90 A, preventing damage to 36 V-rated power management ICs and microcontrollers in powertrain modules. | Use Scenario: Shields sensor signal conditioning inputs and CAN transceiver power rails from coupled transients induced by fuel pump or injector switching. IC Role / Device Role / Timing Role: Secondary TVS placed after primary bulk protection; handles fast-rising edge transients (<100 ns rise time) that bypass upstream filters. Use Value: Low leakage (1 µA) avoids signal offset errors in precision analog front-ends; 185 °C rating allows placement near hot engine compartments. |
| Body Control Module (BCM) Power Input | ADAS Camera Power Rail Protection |
Use Scenario: Guards BCM 12 V supply against jump-start surges, reverse battery connection (with series fuse), and relay coil flyback in lighting and door lock circuits. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry point; coordinates with upstream fuse to clear faults above 400 A IFSM rating. Use Value: 400 A IFSM withstands multiple jump-start events; P600 package provides mechanical robustness against board flex and thermal cycling in pillar-mounted modules. | Use Scenario: Secures 12 V input to image sensor SoCs and serializer ICs in rear-view or surround-view camera modules exposed to under-hood EMI. IC Role / Device Role / Timing Role: Front-end transient suppressor mounted adjacent to connector; minimizes trace inductance to preserve clamping speed and effectiveness. Use Value: 10/1000 µs 6000 W rating covers combined ISO 16750-2 pulse 5a/b severity levels; RoHS + AEC-Q101 ensures compliance for OEM camera BOMs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5BT | Lower PPPM (400 W vs. 6000 W); SMA package (0.25 W PD); 300 A IFSM; same VWM and VC. | Not suitable for load dump; limited to ESD and low-energy inductive spikes in infotainment or telematics. | Select only for non-automotive or secondary protection where energy is <10 J. |
| 1.5KE24A | Higher VBR tolerance (26.7–32.6 V vs. 26.7–30.0 V); DO-201 package; 1500 W PPPM (10/1000 µs); no AEC-Q101 qualification. | Lacks automotive qualification and high-temp stability; requires additional validation for under-hood use. | Acceptable for industrial 12 V systems but not for Tier-1 automotive designs requiring AEC-Q101 documentation. |
Compared with SMAJ24A-E3/5BT and 1.5KE24A, the 6KA24-E3/73 delivers 15× higher surge energy handling, guaranteed AEC-Q101 compliance, and stable clamping up to +150 °C - making it the only option qualified for primary load dump protection in modern 12 V automotive power domains.

The 6KA24-E3/73 maintains predictable voltage limiting even in high-ambient under-hood conditions.
Is the 6KA24-E3/73 RoHS compliant and qualified to AEC-Q101?
Yes, the 6KA24-E3/73 carries the HE3 suffix indicating RoHS compliance and AEC-Q101 qualification. It meets JESD201 Class 2 whisker resistance and is certified for automotive use per stress tests including high-temperature operating life (HTOL) and temperature cycling (TCT). The 6KA24-E3/73 is documented in Vishay's automotive-grade product portfolio.
What package type does the 6KA24-E3/73 use, and what are its key mechanical features?
The 6KA24-E3/73 uses the P600 molded epoxy package with matte tin-plated leads, UL 94 V-0 flammability rating, and 0.360" × 0.340" footprint. Its 1.0" minimum lead length supports through-hole mounting, and the cathode is marked by a color band. The 6KA24-E3/73 is designed for high-power dissipation and mechanical durability in automotive harness and PCB environments.
How does the 6KA24-E3/73 differ from standard 24 V TVS diodes like SMAJ24A?
The 6KA24-E3/73 delivers 6000 W peak pulse power (10/1000 µs), versus 400 W for SMAJ24A-E3/5BT - a 15× higher energy rating essential for automotive load dump. It also features AEC-Q101 qualification, 185 °C TJ max, and P600 packaging for thermal and mechanical robustness. The 6KA24-E3/73 is not a drop-in replacement but a purpose-built solution for primary automotive rail protection.
