Product details
Overview
6KA24-E3/54 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 power systems.
For engineers reviewing the 6KA24-E3/54 datasheet, 6KA24-E3/54 pinout, 6KA24-E3/54 application, or 6KA24-E3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance across temperature, RoHS-compliant packaging details, and direct alternatives for automotive transients suppression design.
Technical Context
This TVS diode uses Vishay's patented PAR® construction to achieve low leakage (<1.0 µA at 24 V, 25 °C), high surge robustness (400 A IFSM), and stable breakdown (26.7–32.6 V at 100 mA), with clamping voltage rising only 5 V from 25 °C to 150 °C (40 → 45 V).
It operates across -65 °C to +185 °C junction temperature, supports soldering at 260 °C for 40 s, meets UL 94 V-0 flammability, and is qualified per AEC-Q101 for automotive under-hood applications requiring high reliability under thermal cycling and mechanical stress.

Applications
| Automotive Load Dump Protection | Engine Control Unit (ECU) Input Protection |
|---|---|
Use Scenario: Voltage spikes up to 120 V induced by alternator field-circuit interruption in 12 V vehicle systems. IC Role / Device Role / Timing Role: TVS diode placed at main power input to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: 6000 W PPPM rating and 40 V clamping ensure downstream 3.3 V/5 V logic remains within absolute maximum ratings during ISO 7637-2 Pulse 5a events. | Use Scenario: ECU exposed to repeated switching noise and load dump pulses during cold cranking and start-stop cycles. IC Role / Device Role / Timing Role: Primary overvoltage protector on 12 V supply rail feeding MCU, CAN transceivers, and sensor interfaces. Use Value: AEC-Q101 qualification and +185 °C TJ max. guarantee uninterrupted operation over full automotive lifetime and temperature range. |
| Body Control Module (BCM) Power Rail | Telematics Unit Battery Backup Line |
Use Scenario: BCM powering lighting, door locks, and HVAC actuators subject to inductive kickback from relay and motor loads. IC Role / Device Role / Timing Role: Bidirectional clamping device on fused 12 V feed, absorbing both positive and negative transients. Use Value: Low 1.0 µA leakage at 24 V prevents battery drain during extended vehicle sleep modes while maintaining fast response (<1 ns). | Use Scenario: Telematics unit retaining GPS and cellular connectivity during engine-off periods using backup battery line. IC Role / Device Role / Timing Role: Standby-mode TVS protecting supercapacitor charging circuit and real-time clock supply from ignition-induced surges. Use Value: Stable VBR (26.7–32.6 V) and minimal VC drift with temperature ensure consistent protection margin across -40 °C to +105 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5A | Lower PPPM (400 W), SMA package, 30 V VBR min., 38.9 V VC @ 9.9 A | Designed for board-level ESD/surge; insufficient for automotive load dump energy | Select only for non-automotive, low-energy transient scenarios where space constraints prohibit P600 |
| 1.5KE24A | Higher VWM (20.5 V), DO-201 package, 61.5 V VC @ 24.3 A, no AEC-Q101 qualification | Lacks automotive qualification and thermal margin; not validated for under-hood use | Acceptable for industrial power supplies but requires additional validation for automotive deployment |
Compared with SMAJ24A-E3/5A and 1.5KE24A, the 6KA24-E3/54 delivers 15× higher surge energy handling, guaranteed AEC-Q101 compliance, and superior thermal stability-making it the only option qualified for primary load dump protection in production automotive ECUs.

FAQ
What is the clamping voltage of the 6KA24-E3/54 at 90 A and 150 °C?
The 6KA24-E3/54 has a maximum clamping voltage of 45 V at 90 A and 150 °C, per Vishay Document Number 88309. This value reflects thermal derating behavior critical for under-hood applications where ambient temperatures exceed 100 °C. The 5 V increase from 25 °C ensures predictable protection margin across full operating range.
Is the 6KA24-E3/54 qualified to AEC-Q101 standards?
Yes, the 6KA24-E3/54 is explicitly AEC-Q101 qualified, as confirmed in its ordering information and mechanical data section. The HE3 suffix denotes high-reliability, automotive-grade qualification including temperature cycling, humidity testing, and mechanical shock validation required for front-end power protection in production vehicles.
What does the "E3/54" suffix mean in 6KA24-E3/54?
The "E3" indicates RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 plating standards; "54" specifies the preferred package code for 13-inch paper tape and reel delivery with 800 units per reel. This matches Vishay's documented ordering format in Document 88309.
Can the 6KA24-E3/54 be used in 24 V commercial vehicle systems?
No-the 6KA24-E3/54 is designed for 12 V automotive systems with 24 V VWM and 40 V clamping; for 24 V nominal systems, Vishay recommends 6KA36-E3/54 (36 V VWM). Using 6KA24-E3/54 in 24 V rails risks premature conduction and accelerated degradation due to sustained reverse bias near VWM.
What is the peak forward surge current rating for the 6KA24-E3/54?
The 6KA24-E3/54 has a peak forward surge current (IFSM) rating of 400 A, measured on an 8.3 ms single half sine-wave per JEDEC JESD22-A112. This enables survival of high-current inrush events such as jump-start conditions or alternator recovery transients without junction failure.
