Product details
Overview
SMB10J6.5AHM3_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 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V clamping voltage (VC) at 89.3 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the SMB10J6.5AHM3_A/H datasheet, SMB10J6.5AHM3_A/H pinout, SMB10J6.5AHM3_A/H application, or SMB10J6.5AHM3_A/H equivalent, key selection criteria include clamping performance under 100 A surge, AEC-Q101 qualification status, unidirectional polarity marking, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown and low leakage (<5 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device is optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, inductive switching spikes, and lightning-induced transients. Its thermal resistance (RθJA = 72 °C/W) and 150 °C max junction temperature support sustained operation in compact, thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 5 V systems. |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - tight breakdown window ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage limits stress on protected ICs during 1000 W transient events. |
| PPPM | 1000 W (10/1000 µs) - energy-handling capacity suitable for ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| ID @ VWM | <5 µA - ultra-low leakage preserves battery life and avoids false triggering in low-power sensor nodes. |
| TJ max | +150 °C - enables use in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected circuit's ground or low-side return path; must handle full IPPM surge current. |
| Cathode | Reverse-biased terminal during normal operation | Connected to protected line (e.g., 5 V rail); color band identifies this terminal for correct orientation in automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in humid environments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without pre-baking, reducing manufacturing complexity and cost. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets EU Directive 2011/65/EU and automotive material compliance requirements (e.g., GMW3172). |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and body electronics. |
| Low profile (0.086" height) | Enables dense PCB layouts in space-constrained modules such as camera ECUs and infotainment power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3_A/H | Same VWM/VBR/VC specs but rated for 600 W PPPM (vs. 1000 W); lower IPPM (50 A vs. 89.3 A). | Not suitable for automotive load dump or high-energy industrial transients requiring ≥1000 W rating. | Select SMB10J6.5AHM3_A/H when 1000 W surge handling is mandatory; choose SMBJ6.5AHE3_A/H only for cost-sensitive consumer designs with lower threat profiles. |
| SMCJ6.5AHE3_A/H | Same electrical specs but in larger SMC (DO-214AB) package; higher RθJA (50 °C/W vs. 72 °C/W) and 1500 W PPPM rating. | Requires larger PCB footprint (0.265" × 0.165" vs. 0.155" × 0.130"); better thermal dissipation but incompatible with SMB-restricted layouts. | Choose SMB10J6.5AHM3_A/H for space-constrained automotive modules; select SMCJ6.5AHE3_A/H only if board area allows and higher thermal margin is needed. |
Compared with SMBJ6.5AHE3_A/H and SMCJ6.5AHE3_A/H, SMB10J6.5AHM3_A/H uniquely balances 1000 W surge capability, AEC-Q101 qualification, and SMB footprint - making it optimal for next-generation automotive ECUs where power density and reliability are co-constrained.

FAQ
What is the clamping voltage of SMB10J6.5AHM3_A/H at its rated peak pulse current?
The SMB10J6.5AHM3_A/H has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current (IPPM) of 89.3 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream ICs see no more than 11.2 V during worst-case transients - critical for protecting 5 V logic interfaces and analog front-ends in automotive applications.
Is SMB10J6.5AHM3_A/H qualified for automotive use?
Yes, SMB10J6.5AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number: 88422, Revision: 09-Jan-2024). The HM3 suffix denotes halogen-free, RoHS-compliant construction with full automotive reliability validation including temperature cycling, high-temperature reverse bias, and ESD testing - making SMB10J6.5AHM3_A/H suitable for engine control, ADAS, and body electronics.
What does the "HM3" suffix indicate in SMB10J6.5AHM3_A/H?
The "HM3" suffix in SMB10J6.5AHM3_A/H specifies halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance. It also confirms AEC-Q101 qualification, distinguishing it from commercial-grade "E3" or "M3" variants - essential for compliance in automotive and green industrial programs.
How does SMB10J6.5AHM3_A/H differ from SMBJ6.5AHE3_A/H?
SMB10J6.5AHM3_A/H delivers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ6.5AHE3_A/H, enabling higher surge current handling (89.3 A vs. 50 A) and broader automotive applicability. Both share identical VWM (6.5 V) and VBR range, but SMB10J6.5AHM3_A/H adds AEC-Q101 qualification and halogen-free materials - confirming SMB10J6.5AHM3_A/H as the higher-performance, automotive-grade variant.
What is the thermal resistance of SMB10J6.5AHM3_A/H, and how does it affect layout?
SMB10J6.5AHM3_A/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 requires adequate copper pour and thermal vias in high-surge applications to maintain TJ ≤ 150 °C; insufficient copper area increases RθJA and risks thermal runaway during repeated transients.
