Product details
Overview
P6SMB100A-E3/5B 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 = 85.5 V), 137 V clamping voltage at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and telecom power rails.
For engineers reviewing the P6SMB100A-E3/5B datasheet, P6SMB100A-E3/5B pinout, P6SMB100A-E3/5B application, or P6SMB100A-E3/5B equivalent, key selection criteria include unidirectional polarity, 85.5 V working voltage, 137 V clamping performance under 4.4 A surge, RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (VBR min = 95.0 V, max = 105 V at 1.0 mA), it avalanches to divert transient energy away from downstream circuitry. Its low incremental surge resistance ensures stable clamping during repetitive 0.01% duty cycle pulses.
Designed for automated SMT placement on PCBs with 0.2" × 0.2" copper pads per terminal, it features glass-passivated junction, meets JESD201 Class 2 whisker resistance, and sustains 100 A non-repetitive forward surge (IFSM) - critical for protecting high-side switch nodes in DC-DC converters and motor drivers.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Same VWM (85.5 V), identical SMB package, but lower PPPM (400 W) and higher VC (156 V at 3.2 A) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 3 or automotive load dump | Select only if system-level surge testing confirms 400 W sufficiency and layout allows tighter thermal management |
| 1.5SMC100A | Higher package thermal mass (SMC/DO-214AB), same VWM/VC specs, but RθJA = 30 °C/W vs. 100 °C/W | Better sustained power handling in high-ambient environments; requires larger PCB footprint (7.11 mm × 6.22 mm) | Prefer when ambient temperature exceeds 85 °C or when multiple surges occur in rapid succession |
Compared with SMAJ100A and 1.5SMC100A, P6SMB100A-E3/5B delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, and MSL Level 1 process readiness - making it the preferred choice for high-volume industrial and telecom SMT production where board space and assembly yield are constrained.

FAQ
What is the maximum clamping voltage of the P6SMB100A-E3/5B under standard test conditions?
The P6SMB100A-E3/5B has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB100A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB100A-E3/5B suitable for automotive applications requiring AEC-Q101 qualification?
No - the P6SMB100A-E3/5B uses the commercial-grade E3 suffix and is not AEC-Q101 qualified. For automotive use, select the P6SMB100AHE3_B variant (with HE3 and _B suffixes), which is explicitly qualified to AEC-Q101 and listed in the ordering table on page 3 of Vishay Document 88370. The P6SMB100A-E3/5B remains appropriate for industrial and telecom applications where AEC-Q101 is not mandated.
What is the thermal resistance and how does it affect PCB layout for the P6SMB100A-E3/5B?
The P6SMB100A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This means each watt of dissipated power raises junction temperature by ~100 °C above ambient. To maintain TJ ≤ 150 °C at 5.0 W steady-state power, ambient must stay below 100 °C - confirming that the P6SMB100A-E3/5B is intended for transient-only operation, not continuous power dissipation.
How does the P6SMB100A-E3/5B differ from bidirectional variants like P6SMB100CA?
The P6SMB100A-E3/5B is unidirectional, with polarity marked by a cathode band and designed for DC line protection where reverse voltage is blocked. In contrast, P6SMB100CA is bidirectional, symmetrical in both directions, and used in AC-coupled or floating signal paths. Their VWM (85.5 V vs. 85.5 V), VBR (95–105 V vs. 95–105 V), and VC (137 V vs. 137 V) match, but the P6SMB100A-E3/5B cannot replace P6SMB100CA in AC applications without circuit redesign.
What is the meaning of the "/5B" suffix in P6SMB100A-E3/5B?
The "/5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This differs from "/52", which indicates a 7-inch reel with 750 units. Both share the same E3 RoHS-compliant commercial-grade construction, but /5B supports high-volume SMT placement lines requiring longer uninterrupted feed. The P6SMB100A-E3/5B is fully compatible with standard SMB pick-and-place nozzles and reflow profiles.
