Product details
Overview
SMB10J6.5AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 6.5 V stand-off voltage, 1000 W peak pulse power (10/1000 µs), and 89.3 A peak pulse current. It clamps transients to ≤11.2 V at rated surge, meeting AEC-Q101 for automotive electronics and protecting MOSFETs, ICs, and sensor signal lines against inductive switching spikes.
For engineers reviewing the SMB10J6.5AHM3/I datasheet, SMB10J6.5AHM3/I pinout, SMB10J6.5AHM3/I application, or SMB10J6.5AHM3/I equivalent, this device is selected for robust overvoltage protection in automotive powertrain control units, industrial motor drives, and DC-DC converter input stages where low clamping voltage and fast response (<1 ns) are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA leakage at 6.5 V, then rapidly avalanches when reverse voltage exceeds 7.22–7.98 V breakdown range (tested at 10 mA). Its glass-passivated junction ensures stable performance across -55 °C to +150 °C junction temperature.
The SMB10J6.5AHM3/I uses a low-inductance, surface-mount SMB package optimized for automated placement and thermal dissipation on 5.0 mm × 5.0 mm copper pads. Its MSL Level 1 rating supports lead-free reflow up to 260 °C peak, and halogen-free construction complies with RoHS and JEDEC JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 6.5 V - Maximum continuous reverse operating voltage before significant conduction begins. |
| Breakdown Voltage (VBR) | 7.22–7.98 V at 10 mA - Confirmed avalanche initiation range ensuring reliable triggering margin above VWM. |
| Clamping Voltage (VC) | ≤11.2 V at 89.3 A - Peak voltage seen by protected circuit during 10/1000 µs surge, limiting stress on downstream components. |
| Peak Pulse Power (PPPM) | 1000 W (10/1000 µs) - Sustains high-energy transients common in automotive load-dump and inductive switch-off events. |
| Junction Temperature Range | -55 °C to +150 °C - Enables deployment in under-hood automotive ECUs and industrial power supplies without derating. |

Applications
| Automotive Powertrain Control Unit | Industrial Motor Drive Input Stage |
|---|---|
Use Scenario: Protecting microcontroller I/O and CAN transceiver power rails from alternator load dump and relay coil flyback in engine control modules. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between 12 V supply and ground, triggered within nanoseconds of overvoltage onset. Use Value: Limits voltage excursion to ≤11.2 V during 1000 W surges, preventing latch-up or gate oxide damage in 3.3 V/5 V logic and CAN PHY circuits. | Use Scenario: Safeguarding gate drivers and current-sense amplifiers from voltage spikes generated by IGBT switching in variable-frequency drives. IC Role / Device Role / Timing Role: Parallel-connected clamping device on DC bus input, absorbing inductive kickback energy before it propagates to control circuitry. Use Value: Withstands 89.3 A peak surge current while maintaining clamping below 11.2 V, preserving signal integrity of isolated feedback paths. |
| Automotive Body Control Module | DC-DC Converter Input Protection |
Use Scenario: Shielding LIN bus transceivers and LED driver ICs from electrostatic discharge and battery reverse-polarity transients in door module assemblies. IC Role / Device Role / Timing Role: Unidirectional TVS mounted directly at connector entry point, referenced to chassis ground. Use Value: AEC-Q101 qualification ensures operation over full automotive temperature range (-40 °C to +125 °C ambient), supporting OEM longevity requirements. | Use Scenario: Preventing input-stage failure in buck converters powering ADAS sensors due to hot-plug or cable discharge events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on VIN pin, coordinated with upstream fuse and downstream ceramic filtering. Use Value: 6.5 V VWM aligns with 5 V–12 V input ranges; low clamping voltage avoids triggering undervoltage lockout during transient suppression. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/A | Same electrical specs (VWM = 6.5 V, VC ≤ 11.2 V), but RoHS-compliant commercial grade (E3), not AEC-Q101 qualified or halogen-free. | Lacks automotive qualification; suitable only for industrial/commercial designs without AEC requirements. | Select SMB10J6.5AHM3/I when AEC-Q101 and halogen-free compliance are mandatory; choose SMBJ6.5AHE3/A for cost-sensitive non-automotive use. |
| SMCJ6.5A-HM3 | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM and clamping voltage. | Requires larger PCB footprint and higher thermal mass; used where surge energy exceeds 1000 W capability. | Choose SMB10J6.5AHM3/I for space-constrained layouts needing 1000 W protection; select SMCJ6.5A-HM3 only if validated surge tests exceed SMB10J6.5AHM3/I's 1000 W rating. |
Compared with SMBJ6.5AHE3/A and SMCJ6.5A-HM3, the SMB10J6.5AHM3/I uniquely delivers AEC-Q101 qualification, halogen-free construction, and SMB footprint in a single 1000 W solution-enabling drop-in compliance for next-generation automotive ECUs without layout revision or thermal redesign.

FAQ
What is the maximum clamping voltage of SMB10J6.5AHM3/I at its rated peak pulse current?
The SMB10J6.5AHM3/I has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current of 89.3 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry sees no more than 11.2 V during worst-case surge events, making SMB10J6.5AHM3/I suitable for safeguarding 5 V and 12 V systems with tight voltage margins.
Is SMB10J6.5AHM3/I qualified for automotive applications?
Yes, SMB10J6.5AHM3/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HM3" (halogen-free, RoHS-compliant, AEC-Q101). It undergoes rigorous stress testing-including temperature cycling, humidity bias, and mechanical shock-to meet automotive electronic control unit requirements, and is explicitly recommended for powertrain, body control, and ADAS subsystems.
What does the "HM3" suffix indicate in SMB10J6.5AHM3/I?
The "HM3" suffix in SMB10J6.5AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade "E3" or "M3" versions and confirms compliance with JEDEC JESD201 Class 2 whisker resistance, UL 94 V-0 molding compound, and automotive reliability standards-making SMB10J6.5AHM3/I appropriate for safety-critical and long-lifecycle deployments.
Can SMB10J6.5AHM3/I be used in bidirectional configurations?
No, SMB10J6.5AHM3/I is a unidirectional TVS diode, as indicated by its part number structure and electrical specifications (e.g., IFSM = 100 A, absence of bidirectional VBR symmetry). For bidirectional protection, Vishay offers the SMB8J6.5CA series; using SMB10J6.5AHM3/I in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche capability.
What is the thermal resistance from junction to ambient for SMB10J6.5AHM3/I?
The typical thermal resistance from junction to ambient (RθJA) for SMB10J6.5AHM3/I is 72 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB construction and defines safe power derating above 25 °C ambient-critical for thermal design validation in enclosed automotive enclosures where ambient may reach 105 °C.
