Product details
Overview
P6SMB110CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients up to 152 V at 3.9 A peak pulse current (10/1000 μs), with 600 W peak pulse power rating and 94.0 V stand-off voltage - deployed for ESD and surge protection on signal lines of automotive sensor units and industrial I/O interfaces.
For engineers reviewing the P6SMB110CA-M3/5B datasheet, P6SMB110CA-M3/5B pinout, P6SMB110CA-M3/5B application, or P6SMB110CA-M3/5B equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and real-world design implications for transient suppression in 12–48 V systems.
Technical Context
The P6SMB110CA-M3/5B implements a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced surges, with symmetrical breakdown (VBR min/max = 105/116 V) and clamping voltage (VC = 152 V) measured at 3.9 A IPPM. Its bidirectional architecture eliminates polarity dependency, enabling direct placement across differential or AC-coupled signal paths without orientation checks.
Thermally, it features RθJL = 20 °C/W to leads and operates from –65 °C to +150 °C junction temperature, with MSL Level 1 moisture sensitivity and halogen-free, RoHS-compliant construction (M3 suffix). The device sustains repetitive 10/1000 μs pulses at 0.01% duty cycle when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single high-energy transients common in automotive load-dump or industrial relay switching without failure |
| Stand-off Voltage (VWM) | 94.0 V - maximum continuous reverse voltage before significant leakage; sets upper limit for normal operating rail voltage |
| Breakdown Voltage (VBR) | 105–116 V at 1 mA - symmetric conduction threshold in both directions; defines minimum overvoltage triggering point |
| Clamping Voltage (VC) | 152 V at 3.9 A IPPM - actual voltage seen by protected circuit during surge; determines downstream component voltage stress |
| Peak Pulse Current (IPPM) | 3.9 A - maximum non-repetitive surge current the device can shunt while maintaining specified VC |
| Junction Temperature Range | –65 °C to +150 °C - supports under-hood automotive and industrial environments without derating below –40 °C ambient |
| Thermal Resistance (RθJA) | 100 °C/W - requires PCB copper area management for sustained power dissipation; limits average power handling to ~50 mW at 50 °C ambient |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant (M3 suffix), with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking - bidirectional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Either terminal conducts equally during positive or negative overvoltage events; no orientation required during placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded sensor outputs without polarity constraints |
| 600 W peak pulse power | Meets ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surge immunity requirements for automotive and industrial equipment |
| 152 V clamping at 3.9 A | Limits voltage overshoot to safe levels for 100 V-rated interface ICs (e.g., CAN transceivers, analog front-ends) during 10/1000 μs transients |
| AEC-Q101 qualified (with -B suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - critical for ADAS and body control modules |
| MSL Level 1, 260 °C reflow | Compatible with standard lead-free SMT assembly processes without pre-baking; reduces manufacturing complexity and cost |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA-T | Same VWM (94 V), identical SMB package, but lower PPPM (600 W same), higher VC (156 V), and no AEC-Q101 option | Commercial-grade only; not validated for automotive temperature cycling or HTRB stress | Select when AEC-Q101 qualification is unnecessary and cost optimization is prioritized over automotive reliability assurance |
| 1.5KE110CA | Higher power (1500 W), axial DO-15 package, VC = 177 V at 8.5 A, larger footprint and manual assembly incompatible with automated SMT lines | Requires through-hole rework or adapter board; unsuitable for space-constrained PCBs or high-volume pick-and-place | Choose only for legacy designs requiring higher energy absorption where SMB footprint and SMT compatibility are secondary concerns |
Compared with SMBJ110CA-T and 1.5KE110CA, the P6SMB110CA-M3/5B uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB SMT compatibility - making it the optimal choice for new automotive and industrial designs demanding production scalability and long-term reliability validation.

FAQ
What is the clamping voltage of the P6SMB110CA-M3/5B at its rated peak pulse current?
The P6SMB110CA-M3/5B has a maximum clamping voltage (VC) of 152 V at 3.9 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during a full-rated surge event. The P6SMB110CA-M3/5B maintains this clamping performance bidirectionally, ensuring consistent protection regardless of surge polarity.
Is the P6SMB110CA-M3/5B AEC-Q101 qualified?
The P6SMB110CA-M3/5B itself is not AEC-Q101 qualified; however, the P6SMB110CAHM3_B variant (same electrical specs, -B suffix) is fully AEC-Q101 qualified per Vishay's ordering matrix. The "M3" suffix denotes halogen-free and RoHS compliance, while "B" indicates automotive qualification. For automotive applications requiring formal qualification, specify P6SMB110CAHM3_B instead of P6SMB110CA-M3/5B.
What does the "CA" suffix mean in P6SMB110CA-M3/5B?
The "CA" suffix in P6SMB110CA-M3/5B explicitly denotes a bidirectional Transient Voltage Suppressor - meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants (e.g., P6SMB110A), the CA version has no cathode band marking and functions identically in either orientation, simplifying layout and eliminating polarity verification during assembly.
What is the thermal resistance of the P6SMB110CA-M3/5B, and how does it affect PCB layout?
The P6SMB110CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal. This value implies that sustained power dissipation above ~50 mW will cause significant junction temperature rise - so the device is intended for transient, not continuous, power handling. PCB layout must adhere to Vishay's specified pad dimensions to ensure rated surge capability and avoid thermal runaway during repetitive events.
Can the P6SMB110CA-M3/5B replace a unidirectional TVS like P6SMB110A in an existing design?
No - the P6SMB110CA-M3/5B cannot directly replace a unidirectional P6SMB110A without circuit review. While both share identical VWM (94 V), VBR, and VC ratings, the unidirectional part blocks reverse current until breakdown, whereas the CA version conducts in both directions. Substituting it into a DC-biased line (e.g., 5 V logic rail) may cause unintended leakage or shorting. Always verify bias conditions and signal topology before interchanging unidirectional and bidirectional TVS devices like the P6SMB110CA-M3/5B.
