Product details
Overview
SMB10J11AHM3_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 11 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR) at 1 mA, 18.2 V clamping voltage (VC) at 54.9 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface and power supply protection.
For engineers reviewing the SMB10J11AHM3_A/H datasheet, SMB10J11AHM3_A/H pinout, SMB10J11AHM3_A/H application, or SMB10J11AHM3_A/H equivalent, key selection criteria include clamping performance under 100 A surge, thermal resistance (RθJA = 72 °C/W), AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its response time is sub-nanosecond, enabling effective suppression of ESD and inductive switching transients per IEC 61000-4-2 and ISO 7637-2.
The device is rated for -55 °C to +150 °C operating junction temperature, with MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility. It delivers 1000 W peak pulse power when mounted on 0.2" × 0.2" copper pads - critical for automotive power rail hardening where sustained surge energy must be dissipated without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - maximum continuous reverse working voltage before leakage exceeds 5 µA; defines safe DC operating margin for 12 V automotive systems. |
| VBR (min/max) | 12.2 V / 13.5 V at IT = 1 mA - tight breakdown window ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 18.2 V at 54.9 A - clamping voltage limits downstream IC stress during 10/1000 µs surges; enables robust protection of 16 V-tolerant receivers. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 µs waveform; supports ISO 7637-2 Pulse 5a (load dump) simulation. |
| RθJA | 72 °C/W - thermal resistance from junction to ambient on standard PCB pad layout; informs derating above 25 °C ambient. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
| Package | SMB (DO-214AA) - surface-mount package with 2.20 mm × 3.94 mm body, compatible with high-speed pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by color band on one end. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11AHE3_A/H | Same VWM (11 V), VBR (12.2–13.5 V), and VC (18.2 V), but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a load dump simulation. | Select only when system-level surge energy is confirmed ≤600 W and AEC-Q101 is not required. |
| SMCJ11A-HM3_A/H | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 35 °C/W vs. 72 °C/W. | Better thermal performance allows higher average power handling, but requires 30% more PCB area. | Choose when board space permits and junction temperature rise must be minimized under repeated surge duty cycles. |
Compared with SMBJ11AHE3_A/H and SMCJ11A-HM3_A/H, SMB10J11AHM3_A/H uniquely balances 1000 W surge capacity, AEC-Q101 qualification, and compact SMB footprint - making it optimal for space-constrained automotive modules requiring full load dump immunity.

FAQ
What is the peak pulse power rating of SMB10J11AHM3_A/H?
The SMB10J11AHM3_A/H has a peak pulse power rating (PPPM) of 1000 W with a 10/1000 µs waveform when mounted on 0.2" × 0.2" copper pads. This rating is validated per ANSI/IEEE C62.35 and enables protection against severe automotive load dump events. The 1000 W capability distinguishes SMB10J11AHM3_A/H from lower-rated alternatives like SMBJ11AHE3_A/H (600 W), making it suitable for demanding AEC-Q101 applications where full ISO 7637-2 Pulse 5a compliance is required.
Is SMB10J11AHM3_A/H qualified for automotive use?
Yes, SMB10J11AHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 88422 datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness - essential for under-hood and cabin electronics. The part is explicitly designated for automotive applications in Vishay's ordering information, and its thermal and surge performance aligns with ISO 16750-2 and ISO 7637-2 requirements.
What does the "HM3" suffix indicate in SMB10J11AHM3_A/H?
The "HM3" suffix in SMB10J11AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It replaces legacy "E3" (RoHS commercial) and "HE3" (RoHS + AEC-Q101) variants by adding halogen-free molding compound - meeting stringent automotive environmental mandates such as VW 80101 and GMW3172. This suffix also confirms compliance with JESD 201 Class 2 whisker resistance and MSL Level 1 reflow profile.
How does the clamping voltage of SMB10J11AHM3_A/H compare to its breakdown voltage?
SMB10J11AHM3_A/H has a minimum breakdown voltage (VBR) of 12.2 V at 1 mA test current and a maximum clamping voltage (VC) of 18.2 V at 54.9 A peak pulse current. The 6.0 V differential reflects its low incremental surge resistance, ensuring minimal voltage overshoot during high-current transients. This design margin allows safe interfacing with 16 V-tolerant ICs while maintaining robust protection - a key advantage over higher-VC alternatives that risk exceeding downstream device absolute maximum ratings.
What PCB layout guidance applies to SMB10J11AHM3_A/H for optimal thermal performance?
For optimal thermal performance, SMB10J11AHM3_A/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay 88422 datasheet. This layout achieves the rated RθJA of 72 °C/W; reducing pad size increases thermal resistance and reduces surge current derating above 25 °C ambient. Thermal vias under pads are recommended for high-duty-cycle applications, and adjacent traces should avoid constriction to maintain heat spreading efficiency.
