Product details
Overview
SMB10J6.5AHE3/52 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 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 ECUs and industrial sensor interfaces.
For engineers reviewing the SMB10J6.5AHE3/52 datasheet, SMB10J6.5AHE3/52 pinout, SMB10J6.5AHE3/52 application, or SMB10J6.5AHE3/52 equivalent, key selection criteria include clamping performance under 100 A surge, AEC-Q101 qualification for automotive use, RoHS compliance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its breakdown threshold to divert transient energy to ground. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and inductive switching transients.
Designed for surface-mount integration, it meets MSL Level 1 per J-STD-020 (260 °C reflow peak), supports 150 °C maximum junction temperature, and delivers thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead) - critical for sustained surge handling in compact PCB layouts.
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 - precise breakdown window ensuring reliable turn-on margin above VWM |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage during 10/1000 µs surge defines protected circuit's max overvoltage stress |
| PPPM | 1000 W - peak pulse power rating determines survivability against IEC 61000-4-5 Level 4 surges |
| ID @ VWM | ≤1000 µA - low leakage preserves efficiency in battery-powered or high-impedance sensor circuits |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-E3/52 | Same SMB package, identical VWM/VBR/VC specs, but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; suitable for consumer/industrial where AEC-Q101 not mandated | Select SMBJ6.5A-E3/52 only if AEC-Q101 is unnecessary and cost optimization is prioritized |
| 1.5SMC6.5A | Higher-power SMC package (1500 W PPPM), same 6.5 V VWM, but larger footprint (0.285" × 0.235") | Better suited for higher-energy surges (e.g., telecom AC/DC front ends), less space-constrained designs | Choose 1.5SMC6.5A when >1000 W surge margin is required and PCB area allows SMC footprint |
Compared with SMBJ6.5A-E3/52, SMB10J6.5AHE3/52 adds AEC-Q101 qualification for automotive deployment; versus 1.5SMC6.5A, it trades 500 W peak power for 30% smaller SMB footprint - optimizing board space in ECU and sensor modules.

FAQ
What is the clamping voltage of SMB10J6.5AHE3/52 and how is it measured?
The SMB10J6.5AHE3/52 has a maximum clamping voltage (VC) of 11.2 V, measured at 89.3 A peak pulse current using a standardized 10/1000 µs double-exponential waveform. This value represents the maximum voltage seen across the device during surge conduction and directly defines the overvoltage stress imposed on protected downstream circuitry. The test condition is specified in Vishay document 88422 and aligns with ANSI/IEEE C62.35 standards.
Is SMB10J6.5AHE3/52 suitable for automotive applications?
Yes, SMB10J6.5AHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix, confirming validation across temperature cycling, highly accelerated life testing, and ESD robustness. It is deployed in engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is critical. The SMB10J6.5AHE3/52 meets all requirements for under-hood and cabin-mounted systems per AEC-Q101 Rev D.
What is the difference between SMB10J6.5AHE3/52 and SMBJ6.5A-E3/52?
SMB10J6.5AHE3/52 and SMBJ6.5A-E3/52 share identical electrical specifications (VWM = 6.5 V, VBR = 7.22–7.98 V, VC = 11.2 V) and SMB package dimensions, but differ in qualification: SMB10J6.5AHE3/52 is AEC-Q101 qualified and RoHS-compliant, while SMBJ6.5A-E3/52 is commercial-grade only. The "HE3" suffix denotes automotive qualification; "E3" indicates RoHS-compliant commercial grade. Both use matte tin-plated leads and meet J-STD-002 solderability.
What is the maximum operating temperature for SMB10J6.5AHE3/52?
The SMB10J6.5AHE3/52 has a maximum junction temperature (TJ max) of +150 °C, verified per Vishay's thermal characterization and AEC-Q101 stress testing. This rating enables continuous operation in high-ambient environments such as automotive engine compartments or industrial motor drives. Derating curves in document 88422 show usable power dissipation down to 50% at 125 °C ambient when mounted on 5.0 mm × 5.0 mm copper pads.
Does SMB10J6.5AHE3/52 have polarity marking and how is it identified?
Yes, SMB10J6.5AHE3/52 is unidirectional and features a visible cathode band (dark stripe) on the SMB package body, located near the cathode terminal. Per Vishay mechanical drawings and JEDEC DO-214AA standard, the banded end corresponds to the cathode, which must be connected to system ground for proper transient shunting. No marking appears on bidirectional variants, but SMB10J6.5AHE3/52 is strictly unidirectional and always marked.
