Product details
Overview
SMB10J6.5AHE3_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 with 6.5 V stand-off voltage, 11.2 V clamping voltage at 89.3 A peak pulse current, and 1000 W peak pulse power rating. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and microcontroller I/O pins against inductive switching transients and ESD.
For engineers reviewing the SMB10J6.5AHE3_A/I datasheet, SMB10J6.5AHE3_A/I pinout, SMB10J6.5AHE3_A/I application, or SMB10J6.5AHE3_A/I equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25 °C, unidirectional polarity marking, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 6.5 V stand-off (VWM), it avalanches near its 7.22–7.98 V breakdown range (VBR at 10 mA), limiting transient energy by diverting up to 89.3 A (IPPM) while clamping to ≤11.2 V (VC). Its glass-passivated junction ensures stable leakage (<5 µA at VWM) and fast response time (<1 ns).
Thermal design relies on low RθJL (20 °C/W) and moderate RθJA (72 °C/W), requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for full 1000 W rating. The device is rated for -55 °C to +150 °C operation and meets MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 7.22 V / 7.98 V at 10 mA - guaranteed avalanche onset window for reliable turn-on margin |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage under 10/1000 µs surge, defining worst-case protected node stress |
| PPPM | 1000 W - peak pulse power handling capability with standard 10/1000 µs waveform |
| ID @ VWM | <5 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |

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/I | Same VWM (6.5 V), lower PPPM (600 W), lower IPPM (62.2 A), identical SMB package and AEC-Q101 qualification | Lower surge capacity suits cost-sensitive consumer or non-critical industrial nodes | Select when 600 W peak power suffices and BOM cost optimization is prioritized over headroom |
| SMAJ6.5AHE3_A/I | Same VWM (6.5 V), same AEC-Q101, but SMA (DO-214AC) package - smaller footprint, higher thermal resistance (RθJA = 110 °C/W) | Space-constrained layouts where 1000 W rating must be maintained via enhanced PCB copper | Choose only with verified 5.0 mm × 5.0 mm pad layout and thermal simulation confirming TJ < 150 °C |
Compared with SMBJ6.5AHE3_A/I and SMAJ6.5AHE3_A/I, SMB10J6.5AHE3_A/I delivers 67% higher surge power handling in the same footprint as SMBJ, while offering better thermal performance than SMAJ-making it optimal for automotive front-end and high-reliability industrial interfaces where margin matters.

FAQ
What is the clamping voltage of SMB10J6.5AHE3_A/I at its rated peak pulse current?
The SMB10J6.5AHE3_A/I has a maximum clamping voltage (VC) of 11.2 V when subjected to its peak pulse current (IPPM) of 89.3 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 defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMB10J6.5AHE3_A/I maintains this clamping performance across its operational temperature range when properly derated.
Is SMB10J6.5AHE3_A/I suitable for automotive applications?
Yes, SMB10J6.5AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It meets stringent requirements for temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness. The SMB10J6.5AHE3_A/I is deployed in engine control units, ADAS camera modules, and body electronics where protection against load dump and ISO 7637-2 pulses is critical.
What does the "_A/I" suffix mean in SMB10J6.5AHE3_A/I?
The "_A/I" suffix in SMB10J6.5AHE3_A/I denotes the revision code ("A") and tape-and-reel packaging option ("I"), where "I" specifies 3200 units per 13-inch diameter reel. This matches Vishay's ordering convention in Document Number 88422: "SMB10J6.5AHE3_B/I" and "SMB10J6.5AHE3_A/I" both indicate AEC-Q101 qualified parts in 13″ reels. The "A" revision reflects the latest tested and released version per the January 2024 datasheet revision.
How does SMB10J6.5AHE3_A/I differ from bidirectional variants like SMB8J6.5CAHE3_A/I?
The SMB10J6.5AHE3_A/I is unidirectional with cathode marking and optimized for DC-biased lines (e.g., VCC-to-ground or signal-to-ground), whereas SMB8J6.5CAHE3_A/I is bidirectional, symmetrical, and suited for AC or differential lines (e.g., RS-485, CAN). SMB10J6.5AHE3_A/I offers higher peak pulse power (1000 W vs. 800 W) and higher IPPM (89.3 A vs. 71.4 A) due to its larger die structure, confirmed in Vishay's Table "UNIDIRECTIONAL" on page 2 of document 88422.
What is the thermal resistance from junction to lead (RθJL) for SMB10J6.5AHE3_A/I?
The SMB10J6.5AHE3_A/I has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the "THERMAL CHARACTERISTICS" table on page 4 of Vishay document 88422. This low value enables efficient heat transfer from the silicon die to the PCB copper through the leads, supporting sustained surge duty cycles when mounted on recommended 5.0 mm × 5.0 mm pads. The SMB10J6.5AHE3_A/I's RθJL directly impacts safe operating area during repetitive transient events.
