Product details
Overview
SMPC36ANHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for robust overvoltage protection of sensitive electronics. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and low clamping voltage of 58.1 V at 25.8 A, making it suitable for automotive-grade protection of MOSFETs and sensor signal lines.
For engineers reviewing the SMPC36ANHM3/I datasheet, SMPC36ANHM3/I pinout, SMPC36ANHM3/I application, or SMPC36ANHM3/I equivalent, this device is evaluated for high-energy transient suppression in AEC-Q101-compliant automotive subsystems, industrial control I/O, and telecom interface protection where fast response (<1 ns), low incremental surge resistance, and MSL Level 1 reflow compatibility are critical.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown. Its TO-277A (SMPC) package enables dual-anode/dual-cathode configuration with cathode band marking, supporting both anode- and cathode-on-heatsink mounting per JEDEC 51-14 thermal test method.
It delivers 1500 W peak pulse power under 10/1000 μs waveform, with thermal resistance junction-to-mount (RθJM) ≤3 °C/W and junction-to-ambient (RθJA) ≤100 °C/W on FR4 PCB. The device is rated for -55 °C to +150 °C operating temperature and meets JESD201 Class 2 whisker resistance.

FAQ
What is the exact breakdown voltage range for SMPC36ANHM3/I?
The SMPC36ANHM3/I has a guaranteed breakdown voltage (VBR) range of 40.0 V to 44.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche turn-on behavior across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is SMPC36ANHM3/I compatible with lead-free reflow soldering processes?
Yes, SMPC36ANHM3/I meets MSL Level 1 per J-STD-020 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and it passes JESD201 Class 2 whisker testing-ensuring reliable solder joint formation without preconditioning.
How does the SMPC (TO-277A) package differ from standard SMB or SMC packages?
The SMPC (TO-277A) package used by SMPC36ANHM3/I measures 4.80 mm × 4.40 mm with 1.1 mm typical height-35 % smaller than DO-214AB (SMC) and 20 % lower than DO-214AA (SMB). Its dual-anode/dual-cathode internal structure enables flexible heatsinking options, and its JEDEC-compliant pad layout supports automated placement without tombstoning.
Does SMPC36ANHM3/I require external series impedance for optimal clamping performance?
No external series impedance is required for basic clamping operation of SMPC36ANHM3/I. However, in high-frequency ESD protection scenarios, a small series resistor (e.g., 10 Ω) may be added to limit di/dt and improve system-level IEC 61000-4-2 compliance. The device's low incremental surge resistance ensures effective clamping even with minimal trace inductance.
What is the maximum allowable junction temperature for continuous operation of SMPC36ANHM3/I?
The SMPC36ANHM3/I has a maximum junction temperature (TJ max) of +150 °C, validated per AEC-Q101 stress testing. At TA = 25 °C, its steady-state power dissipation is 1.25 W; derating follows Fig. 2 in the datasheet, reaching zero dissipation at ~150 °C ambient when mounted on FR4 with 2 oz. copper.
