Product details
Overview
SMB10J10AHE3_A/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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage at 5.0 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J10AHE3_A/H datasheet, SMB10J10AHE3_A/H pinout, SMB10J10AHE3_A/H application, or SMB10J10AHE3_A/H equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a clamping-type overvoltage protector using an avalanche junction structure. Its glass-passivated silicon die delivers sub-nanosecond response time to transients and maintains stable clamping performance across -55 °C to +150 °C junction temperature range. The unidirectional configuration enables integration into DC-biased circuits without reverse leakage concerns above VWM.
Thermal design relies on low RθJL (20 °C/W) and moderate RθJA (72 °C/W), requiring minimum 0.2" × 0.2" copper pads per terminal for rated 1000 W pulse handling. The matte tin-plated leads comply with J-STD-002 solderability and JESD22-B102 whisker testing (Class 2).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHE3_A/H | Same VWM (10 V), identical SMB package, but rated for 600 W PPPM (vs. 1000 W); lower IPPM (32.4 A vs. 5.0 A at VC = 17.0 V). | Not suitable for high-energy automotive load dump or industrial 4 kV IEC 61000-4-5 applications requiring full 1000 W rating. | Select SMB10J10AHE3_A/H when peak pulse power >600 W is mandated by system-level surge standards. |
| 1.5SMC10AHE3_A/H | Same VWM and VBR range, but larger SMC (DO-214AB) package; higher thermal mass allows 1500 W PPPM and 100 A IFSM. | Requires larger PCB footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm); less suitable for space-constrained automotive modules. | Choose SMB10J10AHE3_A/H where board area is constrained and 1000 W suffices; use 1.5SMC10AHE3_A/H for higher surge margin and thermal headroom. |
Compared with SMBJ10AHE3_A/H and 1.5SMC10AHE3_A/H, SMB10J10AHE3_A/H uniquely balances AEC-Q101 qualification, 1000 W pulse rating, and compact SMB footprint - making it optimal for automotive and industrial designs needing certified reliability without sacrificing board space.

The SMB10J10AHE3_A/H has a maximum clamping voltage (VC) of 17.0 V at 5.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures downstream ICs experience no more than 17.0 V during surge events, critical for protecting 3.3 V or 5 V logic interfaces. The SMB10J10AHE3_A/H achieves this with low incremental surge resistance and stable avalanche characteristics.
Is SMB10J10AHE3_A/H qualified for automotive applications?
Yes, SMB10J10AHE3_A/H is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and ESD per JS-001. Its RoHS-compliant HE3 suffix and qualification make it suitable for engine control units, body electronics, and ADAS sensor modules. The SMB10J10AHE3_A/H meets automotive reliability requirements without derating at +125 °C ambient.
What is the package type and mounting requirement for SMB10J10AHE3_A/H?
SMB10J10AHE3_A/H uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.29 mm. For full 1000 W pulse rating, it must be mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's recommended layout. The device is MSL Level 1 compliant and compatible with standard reflow profiles peaking at 260 °C, eliminating pre-bake requirements. The SMB10J10AHE3_A/H cathode is marked with a visible band for orientation.
How does SMB10J10AHE3_A/H differ from bidirectional TVS diodes like SMB8J10CAHE3_A/H?
SMB10J10AHE3_A/H is unidirectional and intended for DC-biased lines where polarity is fixed, offering 1000 W PPPM and 5.0 A IPPM at 17.0 V clamping. In contrast, SMB8J10CAHE3_A/H is bidirectional with symmetrical clamping, rated for 800 W PPPM and 10 A IPPM at same VC, suited for AC or floating signal lines. The SMB10J10AHE3_A/H provides tighter VBR tolerance and lower leakage below VWM, making it preferable for precision DC rail protection.
What is the maximum junction temperature and thermal resistance of SMB10J10AHE3_A/H?
The SMB10J10AHE3_A/H has a maximum junction temperature (TJ max) of +150 °C and typical thermal resistance values of RθJL = 20 °C/W (junction-to-lead) and RθJA = 72 °C/W (junction-to-ambient, on 5.0 mm × 5.0 mm pads). These parameters enable reliable operation in under-hood automotive environments and sealed industrial enclosures.
