Product details
Overview
SMB10J10AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 5.0 A peak pulse current, 1000 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J10AHE3/52 datasheet, SMB10J10AHE3/52 pinout, SMB10J10AHE3/52 application, or SMB10J10AHE3/52 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and compliance with automotive reliability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering when reverse voltage exceeds its 11.1–12.3 V breakdown range (VBR at 1.0 mA). Its glass-passivated junction enables fast response (<1 ns) to ESD and lightning-induced transients while maintaining low incremental surge resistance.
Thermal design relies on RθJA = 72 °C/W and RθJL = 20 °C/W, requiring minimum 0.2" × 0.2" copper pads per terminal for rated 1000 W dissipation. The device is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 reflow profile (260 °C peak).

FAQ
What is the clamping voltage of SMB10J10AHE3/52 under a 10/1000 µs surge?
The SMB10J10AHE3/52 has a maximum clamping voltage (VC) of 17.0 V when subjected to a 10/1000 µs waveform at 5.0 A peak pulse current. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during standardized surge events. The SMB10J10AHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is SMB10J10AHE3/52 suitable for automotive applications?
Yes, SMB10J10AHE3/52 is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant, automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, humidity bias, and mechanical shock-making it appropriate for engine control units, body electronics, and ADAS sensor modules. The SMB10J10AHE3/52 meets all requirements for under-hood and cabin-mounted systems.
What does the "HE3" suffix mean in SMB10J10AHE3/52?
The "HE3" suffix in SMB10J10AHE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification. It distinguishes the automotive-grade version from commercial variants (E3/M3) and confirms compliance with JESD201 Class 2 whisker resistance, MSL Level 1 reflow capability, and extended temperature operation. The SMB10J10AHE3/52 is fully traceable and manufactured to automotive process controls.
How does SMB10J10AHE3/52 differ from SMBJ10A-E3/52?
SMB10J10AHE3/52 offers 1000 W peak pulse power versus 600 W for SMBJ10A-E3/52, and a lower clamping voltage of 17.0 V vs. 19.9 V at rated current. It also carries AEC-Q101 qualification (HE3), whereas SMBJ10A-E3/52 is commercial grade (E3). The SMB10J10AHE3/52 is optimized for higher-energy automotive and industrial transients.
What is the thermal resistance of SMB10J10AHE3/52?
The SMB10J10AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per terminal. These values define safe power derating above 25 °C ambient and inform heatsinking decisions. The SMB10J10AHE3/52 must be mounted per recommended pad layout to achieve rated 1000 W performance.
