Product details
Overview
P6SMB100A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM), 137 V clamping voltage at 4.4 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform-designed to protect MOSFETs, ICs, and sensor signal lines in industrial power supplies and automotive control modules.
For engineers reviewing the P6SMB100A-M3/5B datasheet, P6SMB100A-M3/5B pinout, P6SMB100A-M3/5B application, or P6SMB100A-M3/5B equivalent, key selection criteria include unidirectional polarity, 85.5 V maximum reverse standoff, 95.0–105 V breakdown range at 1 mA, thermal resistance of 100 °C/W (junction-to-ambient), and halogen-free RoHS-compliant construction per M3 suffix.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 95.0–105 V), limiting transient-induced overvoltage across protected circuit nodes. Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Designed for automated SMT placement on PCBs with 0.2" × 0.2" copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C) and supports operation from −65 °C to +150 °C junction temperature, with cathode band marking indicating polarity for unidirectional configuration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-T | Same SMB package, identical VWM (85.5 V), VC = 137 V, but rated for 600 W with 10/1000 μs waveform and JEDEC-standardized thermal performance | Widely used in telecom infrastructure; slightly tighter VBR tolerance (±5% vs ±5.3%) | Select when requiring JEDEC-qualified thermal data or broader distributor availability |
| 1.5SMC100A | Larger SMC (DO-214AB) package (2.54 mm height vs 2.20 mm), same electrical specs, higher RθJA (125 °C/W), 1.5 kW peak power rating | Better suited for high-reliability industrial controls where board space allows larger footprint | Choose when needing marginally higher surge endurance or legacy SMC footprint compatibility |
Compared with SMBJ100A-T and 1.5SMC100A, P6SMB100A-M3/5B offers identical clamping performance in a lower-profile SMB package with halogen-free compliance and optimized thermal resistance for dense layouts-making it preferred for space-constrained automotive and embedded designs.

FAQ
What is the maximum clamping voltage of the P6SMB100A-M3/5B under standard test conditions?
The P6SMB100A-M3/5B has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A using the 10/1000 μs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB100A-M3/5B maintains this clamping performance across its full operating temperature range, with derating applied above TA = 25 °C per Figure 2 in the datasheet.
Is the P6SMB100A-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
No, the P6SMB100A-M3/5B is not AEC-Q101 qualified. It carries the M3 suffix indicating halogen-free RoHS compliance for commercial-grade use. For automotive applications, Vishay specifies the P6SMB100AHM3_B variant (with "_B" revision code), which adds AEC-Q101 qualification. Engineers must select P6SMB100AHM3_B/H or P6SMB100AHM3_B/I for under-hood or safety-critical vehicle systems requiring certified reliability.
How does the thermal resistance of the P6SMB100A-M3/5B affect PCB layout requirements?
The P6SMB100A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C at full 5.0 W steady-state dissipation, designers must provide at least this minimum pad area and avoid excessive thermal isolation. Reducing pad size increases RθJA and risks thermal runaway during sustained overvoltage events. The P6SMB100A-M3/5B does not require external heatsinking for typical transient-only operation.
What is the significance of the "5B" in the P6SMB100A-M3/5B ordering code?
The "5B" in P6SMB100A-M3/5B denotes the packaging format: 13-inch diameter plastic tape and reel containing 3200 units. This contrasts with "52", which indicates a 7-inch reel holding 750 units. Both share identical electrical and mechanical specifications; the "5B" variant is optimized for high-volume SMT assembly lines requiring longer uninterrupted feed. The P6SMB100A-M3/5B remains fully compatible with standard SMB pick-and-place equipment and reflow profiles.
Can the P6SMB100A-M3/5B be used in bidirectional transient protection applications?
No, the P6SMB100A-M3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional protection requires a part with "CA" suffix (e.g., P6SMB100CA). Using P6SMB100A-M3/5B in AC or floating-signal applications would result in forward conduction during negative half-cycles, causing failure. For bidirectional use cases like RS-485 or CAN bus protection, engineers must specify the correct CA variant-P6SMB100A-M3/5B is strictly for DC rail or referenced signal line protection.
