Product details
Overview
P6SMB82AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB82AHM3_A/H datasheet, P6SMB82AHM3_A/H pinout, P6SMB82AHM3_A/H application, or P6SMB82AHM3_A/H equivalent, this device delivers verified AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and low incremental surge resistance for robust ESD and lightning surge protection in automotive and industrial environments.
Technical Context
The P6SMB82AHM3_A/H operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and stable clamping under repetitive transient events. Its thermal resistance (RθJA = 100 °C/W) and 150 °C max junction temperature support operation in high-temperature PCB layouts without forced cooling.
Designed for 10/1000 μs waveform compliance, it sustains 5.3 A peak pulse current (IPPM) while limiting clamped voltage to 113 V - critical for safeguarding 72 V nominal DC bus systems and 80 V-rated gate drivers. The cathode-band polarity marking ensures correct orientation during automated placement on SMB (DO-214AA) footprints.

FAQ
What is the maximum clamping voltage of the P6SMB82AHM3_A/H under standard test conditions?
The P6SMB82AHM3_A/H has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the actual voltage seen by downstream components during surge events - critical for ensuring compatibility with 100 V-rated ICs and MOSFETs in the protected circuit. The P6SMB82AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the P6SMB82AHM3_A/H suitable for automotive applications?
Yes, the P6SMB82AHM3_A/H is AEC-Q101 qualified (denoted by the HM3 suffix) and specifically designed for automotive use. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation. The P6SMB82AHM3_A/H is commonly deployed in body control modules, lighting drivers, and infotainment power rails where reliability under harsh thermal and electrical conditions is mandatory.
What does the "HM3" suffix indicate in P6SMB82AHM3_A/H?
The "HM3" suffix in P6SMB82AHM3_A/H signifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade E3/M3 versions and confirms compliance with automotive material standards, including JESD201 Class 2 whisker resistance and MSL Level 1 reflow capability. The P6SMB82AHM3_A/H meets all mechanical, thermal, and electrical requirements defined in the AEC-Q101 stress test standard.
How does the P6SMB82AHM3_A/H compare to bidirectional TVS diodes in the same series?
The P6SMB82AHM3_A/H is unidirectional, meaning it conducts only during reverse-biased transients and blocks forward current - ideal for DC power line protection. Bidirectional variants (e.g., P6SMB82CA) conduct in both directions and are used on AC or differential signal lines. The P6SMB82AHM3_A/H offers tighter leakage (<1 μA at VWM) and lower forward voltage drop than bidirectional equivalents, improving efficiency in DC applications.
What is the thermal resistance and maximum junction temperature of the P6SMB82AHM3_A/H?
The P6SMB82AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on standard 0.2" × 0.2" copper pads, and a maximum operating junction temperature (TJ) of +150 °C. These values enable reliable operation in enclosed enclosures or high-ambient environments such as engine bays or industrial control cabinets - provided PCB layout follows Vishay's recommended pad dimensions. The P6SMB82AHM3_A/H derates linearly above 25 °C ambient per Figure 2 in the datasheet.
