Product details
Overview
SMB10J6.0AHM3_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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 97.1 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J6.0AHM3_A/H datasheet, SMB10J6.0AHM3_A/H pinout, SMB10J6.0AHM3_A/H application, or SMB10J6.0AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking (cathode band), and halogen-free RoHS-compliant construction with MSL Level 1 rating.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<1000 µA at VWM), while the low incremental surge resistance enables effective clamping during fast transients.
Designed for automotive-grade reliability, SMB10J6.0AHM3_A/H meets AEC-Q101 stress tests including temperature cycling, humidity bias, and mechanical shock. Its thermal resistance (RθJA = 72 °C/W) and maximum junction temperature of 150 °C support operation in under-hood environments with limited airflow and elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 5 V systems. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 10.3 V at 97.1 A - Clamped voltage during 10/1000 µs surge; limits stress on protected 5–6 V logic or power stages. |
| PPPM | 1000 W - Peak pulse power handling per 10/1000 µs waveform; supports ISO 7637-2 Pulse 1/2a/5a compliance in automotive. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); protects against load dump-induced forward conduction events. |
| TJ max | +150 °C - Maximum junction temperature; enables placement near heat sources in engine control units or ADAS modules. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 3.94 mm footprint; compatible with standard SMT reflow profiles (peak 260 °C). |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by color band on one end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per datasheet Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or return path; completes shunt path during reverse transient. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery rail or sensor output); marked with color band. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - enables use in ECU, body control, and infotainment modules without additional qualification. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-20E; eliminates brominated flame retardants for safer recycling and regulatory compliance. |
| MSL Level 1 (260 °C peak) | Zero moisture sensitivity; allows unlimited floor life and compatibility with standard lead-free reflow without baking. |
| Glass-passivated junction | Stable VBR tolerance and low leakage (<1000 µA at VWM); prevents parameter drift under thermal cycling and long-term bias stress. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure during surge events - critical for protecting 5 V tolerant interfaces like CAN transceivers or microcontroller I/O. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3_A/H | Same VWM (6.0 V), VBR (6.67–7.37 V), and PPPM (1000 W), but rated only to 125 °C TJ max and not AEC-Q101 qualified. | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment where 150 °C operation is required. | Select SMB10J6.0AHM3_A/H when AEC-Q101 compliance and extended temperature capability are mandatory. |
| SMAJ6.0A-HF | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (~100 °C/W), and no AEC-Q101 qualification. | Acceptable for low-energy consumer electronics but cannot meet ISO 7637-2 Pulse 5a energy requirements in automotive. | Choose SMB10J6.0AHM3_A/H for robust 1000 W surge handling and automotive-grade reliability in space-constrained SMB layout. |
Compared with SMBJ6.0AHE3_A/H and SMAJ6.0A-HF, SMB10J6.0AHM3_A/H uniquely combines 1000 W surge capacity, AEC-Q101 qualification, 150 °C junction rating, and halogen-free construction - making it the only option qualified for demanding automotive power rail protection without design compromise.

FAQ
What is the clamping voltage of SMB10J6.0AHM3_A/H at its rated peak pulse current?
The SMB10J6.0AHM3_A/H has a maximum clamping voltage (VC) of 10.3 V at its peak pulse current (IPPM) of 97.1 A, measured under the standardized 10/1000 µs waveform. This value ensures protected circuits remain within safe operating limits during high-energy transients. The SMB10J6.0AHM3_A/H maintains this clamping performance across its full operating temperature range up to +150 °C junction temperature.
Is SMB10J6.0AHM3_A/H suitable for automotive applications?
Yes, SMB10J6.0AHM3_A/H is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS modules. Its halogen-free HM3 suffix, MSL Level 1 rating, and guaranteed operation from –55 °C to +150 °C make SMB10J6.0AHM3_A/H compliant with stringent automotive reliability and manufacturing requirements.
How does the SMB10J6.0AHM3_A/H differ from the SMBJ6.0AHE3_A/H?
SMB10J6.0AHM3_A/H offers identical electrical specs (VWM = 6.0 V, VBR = 6.67–7.37 V, PPPM = 1000 W) but extends the maximum junction temperature to +150 °C and adds AEC-Q101 qualification - unlike SMBJ6.0AHE3_A/H, which is rated only to +125 °C and lacks automotive qualification. Both share the same SMB package and halogen-free construction.
What is the polarity configuration of SMB10J6.0AHM3_A/H?
SMB10J6.0AHM3_A/H is a unidirectional TVS diode, with cathode identified by a visible color band on the package body. This configuration provides asymmetric clamping - conducting only during reverse-voltage transients - making it ideal for DC power rail protection where forward conduction must be avoided. The SMB10J6.0AHM3_A/H does not conduct in forward bias except during specified IFSM surge events.
Does SMB10J6.0AHM3_A/H require special PCB layout considerations?
Yes - Vishay specifies minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 1000 W pulse power dissipation. Thermal vias under pads and connection to internal ground planes improve heat spreading. The SMB10J6.0AHM3_A/H must be placed as close as possible to the protected node, with short, low-inductance traces to maintain sub-nanosecond response effectiveness.
