Product details
Overview
P6SMB110A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB110A-M3/5B datasheet, P6SMB110A-M3/5B pinout, P6SMB110A-M3/5B application, or P6SMB110A-M3/5B equivalent, this part delivers verified unidirectional transient suppression with halogen-free RoHS compliance, MSL Level 1 rating, and AEC-Q101 qualification option - critical for board-level ESD and surge protection design validation.
Technical Context
The P6SMB110A-M3/5B operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its unidirectional polarity features a cathode band marking and exhibits 94.0 V stand-off voltage (VWM) and ≤1.0 µA reverse leakage at VWM.
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), and is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) - confirming robustness in high-energy transient events.
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 |
|---|---|---|---|
| SMAJ110A-E3/5B | Same VBR range (105–116 V), but lower PPPM = 400 W and higher VC = 177 V at 2.6 A | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when cost sensitivity outweighs surge margin and board space allows parallel devices |
| 1.5SMC110A | Same VBR/VC specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W (lower thermal resistance) | Better thermal performance in high-duty-cycle surge environments; requires larger PCB footprint | Choose for thermally constrained designs where 600 W dissipation must be sustained over multiple pulses |
Compared with SMAJ110A-E3/5B and 1.5SMC110A, the P6SMB110A-M3/5B uniquely balances compact SMB footprint, 600 W rating, and halogen-free compliance - making it optimal for space-constrained automotive and industrial PCBs requiring full AEC-Q101 readiness.

FAQ
What is the clamping voltage of the P6SMB110A-M3/5B under a 10/1000 µs surge?
The P6SMB110A-M3/5B has a maximum clamping voltage (VC) of 152 V at 3.9 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB110A-M3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB110A-M3/5B suitable for automotive applications?
Yes - the P6SMB110A-M3/5B is halogen-free and RoHS-compliant (M3 suffix), and an AEC-Q101 qualified version is available under ordering code P6SMB110AHM3_B/5B. While the base P6SMB110A-M3/5B itself is commercial-grade, its thermal rating (TJ = –65 °C to +150 °C), surge robustness (100 A IFSM), and MSL Level 1 reflow compatibility make it suitable for under-hood and body-control module designs when validated per system-level requirements. The P6SMB110A-M3/5B meets key automotive stress-test thresholds even without formal qualification.
What does the "/5B" suffix indicate in P6SMB110A-M3/5B?
The "/5B" suffix denotes packaging: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume SMT assembly and is distinct from "/52", which indicates a 7-inch reel with 750 units. The "M3" prefix confirms halogen-free, RoHS-compliant construction. Together, P6SMB110A-M3/5B specifies both environmental compliance and logistics-ready packaging for production use. The P6SMB110A-M3/5B is fully compatible with standard pick-and-place equipment calibrated for SMB (DO-214AA) components.
How does the P6SMB110A-M3/5B differ from bidirectional variants like P6SMB110CA?
The P6SMB110A-M3/5B is unidirectional, featuring a cathode band and conducting only in reverse avalanche mode - ideal for DC rail protection where polarity is fixed. In contrast, P6SMB110CA is bidirectional, symmetric in both directions, and used in AC-coupled or floating signal lines. Their VBR and VC values differ: P6SMB110CA has VBR = 105–116 V (bidirectional), same nominal rating but tested across both polarities. The P6SMB110A-M3/5B cannot substitute for P6SMB110CA in AC applications due to inherent polarity dependence.
What is the maximum reverse leakage current for the P6SMB110A-M3/5B at its stand-off voltage?
The P6SMB110A-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 94.0 V, measured at TA = 25 °C. This ultra-low leakage ensures minimal power loss and signal interference in always-on circuits such as automotive wake-up lines or sensor bias networks. The P6SMB110A-M3/5B maintains leakage below 5 µA even at elevated temperatures up to +85 °C, supporting stable operation in thermally demanding environments.
