Product details
Overview
SMB10J6.5AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power 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/I datasheet, SMB10J6.5AHM3_A/I pinout, SMB10J6.5AHM3_A/I application, or SMB10J6.5AHM3_A/I equivalent, key selection criteria include clamping performance under 100 A surge, AEC-Q101 qualification status, halogen-free RoHS compliance, and thermal resistance (RθJA = 72 °C/W) for PCB layout thermal management.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined per ANSI/IEEE C62.35, with guaranteed VC ≤ 11.2 V at IPPM = 89.3 A under standardized 10/1000 µs transients.
Rated for -55 °C to +150 °C operating junction temperature, it supports automotive-grade reliability via AEC-Q101 qualification and meets J-STD-020 MSL Level 1 (260 °C reflow). The matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102, with whisker resistance per JESD 201 Class 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse working voltage before leakage exceeds 10 μA; defines safe operating margin below breakdown |
| VBR (min/max) | 7.22 V / 7.98 V at IT = 10 mA - tight breakdown tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage limits downstream IC stress 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 |
| TJ max. | +150 °C - enables use in under-hood automotive environments without derating at full power |
| RθJA | 72 °C/W - thermal resistance measured on 0.2" × 0.2" copper pads; guides minimum pad area for thermal reliability |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp sub-100 ns ESD and 100 ms load dump pulses. Use Value: Clamps to ≤11.2 V at 89.3 A, preserving signal integrity while meeting ISO 16750-2 and ISO 7637-2 Pulse 5a requirements. |
Use Scenario: Safeguarding 12 V/24 V industrial power supplies feeding PLC I/O modules and motor drivers against lightning-induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary surge suppression device on input rail, coordinated with upstream fuses and downstream LC filters. Use Value: Absorbs 1000 W peak pulses without degradation, enabling compact design with minimal board space vs. multi-stage protection. |
| Consumer USB Power Delivery Port | Telecom Base Station DC Feeds |
Use Scenario: Secondary overvoltage protection on USB-C PD input rails where primary protection is provided by integrated PMICs. IC Role / Device Role / Timing Role: Standby clamping element that activates only during extreme transients exceeding internal regulator limits. Use Value: Low leakage (<10 μA at 6.5 V) prevents standby current drain; fast response avoids latch-up in connected SoCs. |

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/I | Same VWM/VBR/VC specs but commercial-grade (non-AEC-Q101); RθJA = 75 °C/W | Lacks automotive qualification; suitable for consumer/industrial non-automotive designs | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| SMB10J6.5A-E3/52 | Identical electrical specs; RoHS-compliant but not halogen-free; packaging in 7" tape (750 pcs) | No halogen-free certification; limited to non-green manufacturing programs | Choose for legacy BOMs requiring E3 suffix and smaller reel quantities |
Compared with SMB10J6.5AHM3_A/I, SMBJ6.5AHE3_A/I omits AEC-Q101 validation and has slightly higher thermal resistance, while SMB10J6.5A-E3/52 lacks halogen-free compliance and uses different packaging - making SMB10J6.5AHM3_A/I the sole option meeting full automotive green manufacturing requirements.

FAQ
What is the clamping voltage of SMB10J6.5AHM3_A/I at its rated peak pulse current?
The SMB10J6.5AHM3_A/I has a maximum clamping voltage (VC) of 11.2 V at 89.3 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value ensures downstream circuitry remains within safe operating limits during high-energy transients, and is guaranteed across the full operating temperature range of -55 °C to +150 °C. The SMB10J6.5AHM3_A/I datasheet specifies this parameter in the unidirectional electrical characteristics table.
Is SMB10J6.5AHM3_A/I qualified for automotive applications?
Yes, SMB10J6.5AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HM3" (halogen-free, RoHS-compliant, AEC-Q101 qualified). It undergoes stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT) per automotive reliability standards. This makes SMB10J6.5AHM3_A/I suitable for use in engine control units, ADAS sensors, and body electronics modules.
What does the "HM3" suffix indicate in SMB10J6.5AHM3_A/I?
The "HM3" suffix in SMB10J6.5AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes the part from commercial-grade variants (E3/M3) and non-halogen-free automotive versions (HE3). The "_A/I" indicates packaging in 13" tape-and-reel format (3200 pcs), with revision code "A". This full designation ensures traceability to Vishay's material compliance and automotive qualification records for SMB10J6.5AHM3_A/I.
How does SMB10J6.5AHM3_A/I compare to SMBJ6.5AHE3_A/I in thermal performance?
SMB10J6.5AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W on 0.2" × 0.2" copper pads, versus 75 °C/W for SMBJ6.5AHE3_A/I. This 3 °C/W improvement reflects optimized thermal path design in the SMB10J series, supporting higher sustained power dissipation in thermally constrained layouts. Both parts share identical VWM, VBR, and VC specs, but only SMB10J6.5AHM3_A/I combines this thermal advantage with AEC-Q101 and halogen-free compliance.
Can SMB10J6.5AHM3_A/I be used in bidirectional configurations?
No, SMB10J6.5AHM3_A/I is a unidirectional TVS diode, as indicated by its part number structure and electrical specifications (e.g., IFSM = 100 A, VF = 3.5 V at 50 A). Bidirectional variants in the same family carry "C" in the base number (e.g., SMB8J6.5CA). Using SMB10J6.5AHM3_A/I in bidirectional circuits would result in forward conduction during negative transients, potentially damaging the device or failing to protect. For bidirectional protection, select an explicitly designated part such as SMB8J6.5CAHM3_A/I instead of SMB10J6.5AHM3_A/I.
