Product details
Overview
SMB10J24AHM3_B/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 24 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 1 mA, 1000 W peak pulse power (10/1000 μs), 25.7 A peak pulse current (IPPM), and clamps transients to ≤38.9 V. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface protection.
For engineers reviewing the SMB10J24AHM3_B/I datasheet, SMB10J24AHM3_B/I pinout, SMB10J24AHM3_B/I application, or SMB10J24AHM3_B/I equivalent, this page delivers verified electrical specs, automotive-grade qualification status, thermal resistance (RθJA = 72 °C/W), clamping behavior under 10/1000 μs surges, and direct replacement guidance for board-level ESD/surge hardening in ADAS and body control modules.
Technical Context
This TVS operates as a clamping device that remains non-conductive below its 24 V stand-off voltage and rapidly avalanches above its 26.7–29.5 V breakdown threshold to limit transient overvoltage. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, enabling consistent clamping performance across temperature (-55 to +150 °C).
The SMB10J24AHM3_B/I uses a unidirectional configuration with cathode-band polarity marking, supports automated SMT placement per J-STD-020 MSL level 1 (260 °C peak), and meets UL 94 V-0 flammability requirements in its molded SMB package. Its 100 A IFSM rating allows robust handling of 8.3 ms half-sine surges without degradation.

Applications
| Automotive Sensor Interface | Industrial 24 V PLC Input |
|---|---|
Use Scenario: Protecting LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) in vehicle cabin modules from load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between sensor signal line and chassis ground to shunt transients before they reach the ASIC input stage. Use Value: Limits voltage excursion to ≤38.9 V during ISO 7637-2 Pulse 5a (load dump), preserving ADC accuracy and preventing latch-up in 5 V or 3.3 V sensor signal conditioning ICs. | Use Scenario: Safeguarding digital input terminals of programmable logic controllers against field-wiring induced surges in factory automation systems. IC Role / Device Role / Timing Role: Primary surge suppression on 24 V DC input channels, mounted directly at connector entry point before optocoupler or Schmitt trigger input stage. Use Value: Absorbs 1000 W pulses without failure, maintaining <1.0 μA leakage to avoid false triggering of 24 V logic thresholds under normal operation. |
| ADAS Camera Power Rail | Automotive Body Control Module |
Use Scenario: Securing the 12 V or 24 V power supply feeding CMOS image sensors and ISP SoCs in forward-facing driver assistance cameras. IC Role / Device Role / Timing Role: First-line defense against alternator ripple, jump-start spikes, and ESD events on camera module power input traces. Use Value: Clamps transients within 1 ns response time to ≤38.9 V, preventing pixel corruption, reset events, or permanent damage to image processing silicon. | Use Scenario: Protecting microcontroller I/O pins and relay driver outputs in door module ECUs exposed to battery disconnect/reconnect transients. IC Role / Device Role / Timing Role: Bidirectional-capable variant not used; this unidirectional SMB10J24AHM3_B/I guards 24 V switched outputs driving window motors or mirror actuators. Use Value: Withstands 100 A 8.3 ms surge (IFSM), ensuring survival during motor stall conditions while maintaining <1.0 μA standby leakage to extend sleep-mode battery life. |
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_A/H | Same VWM (24 V), VBR (26.7–29.5 V), PPPM (1000 W), but E3 suffix indicates commercial-grade (non-AEC-Q101) and RoHS-compliant only (not halogen-free). | Not qualified for automotive under-hood or safety-critical modules; limited to consumer or industrial environments where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive qualification needs and halogen-free material is not required. |
| SMCJ24A-HM3 | Same VWM/VBR/PPPM specs but in larger SMC (DO-214AB) package; RθJA = 35 °C/W vs. 72 °C/W; higher IFSM (200 A). | Better thermal performance and surge endurance, but requires larger PCB footprint; unsuitable for space-constrained automotive modules. | Choose when board layout allows larger package and higher thermal margin is needed for repeated surge exposure. |
Compared with SMBJ24AHE3_A/H, SMB10J24AHM3_B/I adds AEC-Q101 qualification and halogen-free construction for automotive deployment; versus SMCJ24A-HM3, it trades thermal margin and surge endurance for compact SMB footprint-critical for dense ADAS camera PCBs.

FAQ
What is the maximum clamping voltage of SMB10J24AHM3_B/I under a 10/1000 μs surge?
The SMB10J24AHM3_B/I clamps to a maximum of 38.9 V when subjected to its rated 25.7 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured at TA = 25 °C with mounting on 0.2" × 0.2" copper pads per the Vishay datasheet (Document Number: 88422, Rev. 09-Jan-2024). The SMB10J24AHM3_B/I maintains this clamping performance across its full operating temperature range.
Is SMB10J24AHM3_B/I qualified for automotive applications?
Yes, SMB10J24AHM3_B/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and explicit listing in Vishay's AEC-Q101 qualified product table. It meets stress test requirements for temperature cycling, high-temperature operating life, and mechanical shock, making it suitable for under-hood and cabin automotive modules. The SMB10J24AHM3_B/I also complies with JESD201 Class 2 whisker testing and UL 94 V-0 flammability standards.
What does the "HM3" suffix mean in SMB10J24AHM3_B/I?
The "HM3" suffix in SMB10J24AHM3_B/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 qualification, "M" signifies halogen-free molding compound, and "3" confirms RoHS compliance. The "_B/I" portion specifies packaging: "B" is the revision code, and "I" denotes 13" diameter tape-and-reel delivery (3200 units per reel). This distinguishes SMB10J24AHM3_B/I from commercial-grade variants like SMBJ24A-E3.
How does SMB10J24AHM3_B/I compare to SMBJ24A in terms of surge capability?
SMB10J24AHM3_B/I and SMBJ24A share identical electrical ratings-24 V VWM, 26.7–29.5 V VBR, 1000 W PPPM, and 38.9 V VC-but differ in qualification and materials. SMB10J24AHM3_B/I carries AEC-Q101 qualification and halogen-free construction (HM3), whereas SMBJ24A is commercial-grade (E3/M3). Both use the same SMB package and thermal resistance (RθJA = 72 °C/W), so SMB10J24AHM3_B/I is the drop-in automotive-grade replacement for SMBJ24A where qualification is mandatory.
What is the reverse leakage current of SMB10J24AHM3_B/I at its stand-off voltage?
The SMB10J24AHM3_B/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 24 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage is critical for battery-powered automotive modules and ensures minimal impact on system quiescent current. The SMB10J24AHM3_B/I maintains this specification across its full operating temperature range (-55 to +150 °C), as validated in Vishay's production testing.
