Product details
Overview
SMB10J36AHM3_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 with 1000 W peak pulse power (10/1000 µs), 36 V stand-off voltage (VWM), and 58.1 V clamping voltage at 17.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and MOSFET gate drivers against inductive switching transients.
For engineers reviewing the SMB10J36AHM3_B/H datasheet, SMB10J36AHM3_B/H pinout, SMB10J36AHM3_B/H application, or SMB10J36AHM3_B/H equivalent, this page delivers verified electrical specs, automotive-grade qualification status, thermal resistance (RθJA = 72 °C/W), junction temperature limit (150 °C), and direct replacement guidance for circuit-level ESD/surge hardening.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive electronics, activating when reverse voltage exceeds its breakdown threshold (40.0–44.2 V at 1 mA). Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance, enabling fast response (<1 ns) to transient events like load dump or ISO 7637-2 pulses.
Designed for surface-mount automation, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 (260 °C peak reflow). The halogen-free, RoHS-compliant HM3 suffix confirms compliance with automotive material requirements per AEC-Q101 stress testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHE3_A/H | Same VWM (36 V), same SMB package, but rated for 600 W PPPM (vs. 1000 W) | Lower surge capacity limits use to non-automotive or lower-risk industrial environments | Select when cost sensitivity outweighs need for full AEC-Q101 + 1000 W capability |
| SMCJ36A-Q | Higher power (1500 W), SMC (DO-214AB) package - larger footprint and higher RθJA (50 °C/W) | Requires PCB layout change; better for extreme surge zones (e.g., alternator feed lines) | Choose only if system-level testing confirms need for >1000 W margin and space allows SMC footprint |
Compared with SMBJ36AHE3_A/H and SMCJ36A-Q, SMB10J36AHM3_B/H uniquely balances 1000 W surge capability, AEC-Q101 qualification, halogen-free compliance, and SMB footprint-making it optimal for space-constrained automotive signal-line protection where both reliability and power density matter.

FAQ
What is the clamping voltage of SMB10J36AHM3_B/H at its rated peak pulse current?
The SMB10J36AHM3_B/H has a maximum clamping voltage (VC) of 58.1 V when subjected to its peak pulse current (IPPM) of 17.2 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads), and ensures downstream components see limited overvoltage during surge events. The SMB10J36AHM3_B/H maintains this clamping performance across its qualified operating temperature range.
Is SMB10J36AHM3_B/H suitable for automotive applications?
Yes, SMB10J36AHM3_B/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it approved for automotive use. It passes stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. The SMB10J36AHM3_B/H is specifically intended for protecting automotive subsystems such as sensor interfaces, body control modules, and on-board chargers against ISO 7637-2 and ISO 16750-2 transients.
What does the "HM3_B/H" suffix indicate in SMB10J36AHM3_B/H?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction and AEC-Q101 qualification; "B/H" specifies packaging in 7" diameter plastic tape and reel, with 750 units per reel. This ordering code aligns with Vishay's standardized automotive-grade delivery format. The SMB10J36AHM3_B/H is distinct from commercial-grade variants (e.g., E3/M3) and non-automotive versions (e.g., SMBJ36A), ensuring traceability and compliance for automotive production.
How does SMB10J36AHM3_B/H compare to SMBJ36A in terms of surge capability?
SMB10J36AHM3_B/H delivers 1000 W peak pulse power (10/1000 µs), whereas standard SMBJ36A is rated for 600 W. This 67% higher power rating enables the SMB10J36AHM3_B/H to handle more severe transients without degradation-critical in automotive environments where load dump and alternator surges exceed typical industrial levels. Both share the same VWM (36 V) and SMB package, but only SMB10J36AHM3_B/H carries AEC-Q101 qualification and halogen-free certification.
What is the thermal resistance of SMB10J36AHM3_B/H, and how does it affect layout design?
The SMB10J36AHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal trace length and no internal plane connection. To maintain safe junction temperatures under repeated surges, PCB layout must provide adequate copper area and avoid narrow traces. Derating is required above TA = 25 °C per Figure 2 in the Vishay datasheet 88422; the SMB10J36AHM3_B/H remains functional up to TJ = 150 °C.
