Product details
Overview
SMB10J24AHE3_B/H 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), 38.9 V clamping voltage (VC) at 25.7 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - ideal for automotive power supply rail protection per AEC-Q101.
For engineers reviewing the SMB10J24AHE3_B/H datasheet, SMB10J24AHE3_B/H pinout, SMB10J24AHE3_B/H application, or SMB10J24AHE3_B/H equivalent, this part supports robust ESD and load-dump transient suppression in safety-critical automotive ECUs, industrial sensor interfaces, and 24 V industrial control systems where AEC-Q101 qualification, low clamping voltage, and high surge current handling are mandatory.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated junction and fast response time (<1 ns), enabling effective suppression of inductive switching transients and ISO 7637-2 load-dump pulses. Its 150 °C maximum junction temperature and MSL Level 1 rating support reflow-compatible automated assembly in harsh-environment applications.
The SMB10J24AHE3_B/H delivers 1000 W peak pulse power under standardized 10/1000 µs waveform conditions when mounted on 5.0 mm × 5.0 mm copper pads per JEDEC standards. Its 1.0 µA max reverse leakage at 24 V ensures minimal standby power loss in always-on circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V systems. |
| VBR (min/max) | 26.7 V / 29.5 V at 1 mA - Confirmed breakdown threshold range ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | 38.9 V at 25.7 A - Clamped voltage during 1000 W surge; limits downstream IC stress to <40 V in 24 V systems. |
| PPPM | 1000 W (10/1000 µs) - Sustains high-energy transients typical of automotive load dump without failure. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands repetitive inrush or fault currents without bond-wire fusing. |
| TJ max | +150 °C - Enables operation in engine bay or industrial enclosures without thermal derating penalties. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |

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), identical SMB package, but lower PPPM (600 W) and higher VC (43.0 V at 13.9 A). | Acceptable for non-automotive 24 V systems with lower surge severity (e.g., consumer HVAC controls). | Select SMB10J24AHE3_B/H when 1000 W load-dump immunity or AEC-Q101 compliance is required. |
| SMCJ24AHE3/73 | Higher-power SMC (DO-214AB) package: 1500 W PPPM, 44.0 V VC at 34.1 A, same VWM/VBR. | Suitable where PCB space allows larger footprint and thermal mass improves sustained surge handling. | Choose SMB10J24AHE3_B/H for space-constrained automotive modules; SMCJ24AHE3/73 for industrial power supplies needing extra margin. |
Compared with SMBJ24AHE3_A/H and SMCJ24AHE3/73, SMB10J24AHE3_B/H uniquely balances AEC-Q101 qualification, 1000 W surge capability, and SMB footprint - making it optimal for volume automotive electronics where reliability, size, and cost must coexist.

FAQ
What is the clamping voltage of SMB10J24AHE3_B/H at its rated peak pulse current?
The SMB10J24AHE3_B/H has a maximum clamping voltage (VC) of 38.9 V at 25.7 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value ensures that downstream components connected to a 24 V rail remain within safe operating voltage limits during surge events. The SMB10J24AHE3_B/H maintains this clamping performance across its qualified temperature range and after repeated surge exposure per AEC-Q101 test conditions.
Is SMB10J24AHE3_B/H suitable for automotive applications?
Yes, SMB10J24AHE3_B/H is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensors. Its construction - glass-passivated junction, MSL Level 1 reflow compatibility, and validated performance across -55 °C to +150 °C - meets stringent automotive reliability requirements. The SMB10J24AHE3_B/H is marked with HE3 suffix to denote RoHS-compliant and AEC-Q101-qualified status per Vishay's ordering nomenclature.
How does SMB10J24AHE3_B/H differ from SMBJ24AHE3_A/H?
SMB10J24AHE3_B/H offers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ24AHE3_A/H, with a lower clamping voltage (38.9 V vs. 43.0 V at rated IPPM). Both share the same VWM (24 V) and SMB package, but only SMB10J24AHE3_B/H is rated for automotive load-dump immunity per ISO 7637-2. The SMB10J24AHE3_B/H also uses a reinforced die structure to sustain higher surge energy without parameter shift.
What is the reverse leakage current specification for SMB10J24AHE3_B/H at 24 V?
At 24 V reverse standoff voltage (VWM) and TA = 25 °C, SMB10J24AHE3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage preserves system efficiency in always-on automotive modules and prevents unintended biasing of sensitive analog front-ends. The SMB10J24AHE3_B/H maintains leakage below 5.0 µA even at 125 °C junction temperature per datasheet derating curves.
Can SMB10J24AHE3_B/H be used in bidirectional configurations?
No, SMB10J24AHE3_B/H is a unidirectional TVS diode, as indicated by the "J" (not "JC") in its part number and confirmed by its single cathode band marking. For bidirectional protection on AC or differential lines, Vishay offers the SMB8J24CA family with symmetric breakdown characteristics. Using SMB10J24AHE3_B/H in reverse-biased mode would result in uncontrolled conduction and potential failure; always verify polarity during placement.
