Vishay General Semiconductor - Diodes Division P6SMB110A-M3/52

Overview

P6SMB110A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 110 V breakdown voltage (V_BR = 105–116 V at I_T = 1.0 mA), 152 V maximum clamping voltage (V_C) at 3.9 A peak pulse current (I_PPM), and 600 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD events.

For engineers reviewing the P6SMB110A-M3/52 datasheet, P6SMB110A-M3/52 pinout, P6SMB110A-M3/52 application, or P6SMB110A-M3/52 equivalent, this device delivers verified unidirectional clamping performance in SMB (DO-214AA) package, with halogen-free RoHS compliance, MSL Level 1 rating, and AEC-Q101 qualification available in related variants - critical for automotive, industrial, and telecom power rail protection design.

Technical Context

The P6SMB110A-M3/52 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages and low incremental surge resistance for stable clamping under repetitive 10/1000 μs pulses. Its unidirectional polarity uses cathode-band marking and exhibits 94.0 V stand-off voltage (V_WM) with only 1.0 μA maximum reverse leakage at rated V_WM.

Thermally, it supports operation from –65 °C to +150 °C junction temperature, with R_θJA = 100 °C/W and R_θJL = 20 °C/W, and is rated for 100 A non-repetitive forward surge current (I_FSM) per 8.3 ms half-sine wave - confirming suitability for high-energy transient suppression without thermal runaway under defined PCB pad layout (0.2" × 0.2" copper).

FAQ

What is the maximum clamping voltage of the P6SMB110A-M3/52 under a 10/1000 μs surge?

The P6SMB110A-M3/52 has a maximum clamping voltage (V_C) of 152 V at 3.9 A peak pulse current (I_PPM) under the standard 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and reflects the actual voltage imposed on the protected circuit during full-rated transient events - critical for verifying margin against downstream component voltage ratings.

Is the P6SMB110A-M3/52 halogen-free and RoHS-compliant?

Yes, the P6SMB110A-M3/52 carries the "M3" suffix, which explicitly denotes halogen-free, RoHS-compliant construction per Vishay's ordering nomenclature. This meets EU RoHS Directive 2011/65/EU and IPC-1752A material declaration requirements - confirmed in the "MECHANICAL DATA" section of the official datasheet (Document Number: 88370).

Does the P6SMB110A-M3/52 have AEC-Q101 qualification?

The base P6SMB110A-M3/52 is not AEC-Q101 qualified; however, Vishay offers AEC-Q101 variants under ordering codes such as P6SMB110AHM3_B/H (with "_B" or "_D" suffix indicating qualification). The M3/52 variant itself is commercial-grade, but shares identical electrical and thermal specs - allowing direct evaluation before qualifying the automotive-grade version.

What is the standoff voltage (V_WM) of the P6SMB110A-M3/52, and why does it matter?

The P6SMB110A-M3/52 has a maximum reverse standoff voltage (V_WM) of 94.0 V, meaning it remains effectively non-conductive up to this DC or RMS voltage level. This parameter ensures no significant leakage current (<1.0 μA) flows during normal operation - preserving system efficiency and preventing false triggering, especially important in always-on 24 V or 48 V power rails.

Can the P6SMB110A-M3/52 be used in bidirectional configurations?

No - the P6SMB110A-M3/52 is strictly unidirectional, indicated by the "A" suffix and cathode-band marking. For bidirectional operation, Vishay specifies the "CA" suffix (e.g., P6SMB110CA). Using the unidirectional P6SMB110A-M3/52 in reverse-biased AC applications would result in forward conduction and failure; correct polarity orientation is mandatory.
