Product details
Overview
P6SMB110CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 110 V breakdown voltage (VBR = 105–116 V at IT = 1 mA), 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power rating under 10/1000 µs waveform. It protects signal lines and power rails in sensor units, industrial controllers, and telecom interfaces against ESD and inductive switching transients.
For engineers reviewing the P6SMB110CA-M3/52 datasheet, P6SMB110CA-M3/52 pinout, P6SMB110CA-M3/52 application, or P6SMB110CA-M3/52 equivalent, this device serves as a halogen-free, RoHS-compliant, commercial-grade transient suppressor with MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and verified bidirectional clamping symmetry for robust overvoltage protection in space-constrained PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of voltage polarity-critical for AC-coupled or differential signal lines. Its glass-passivated junction ensures stable leakage (<1 µA at VWM = 94 V) and fast response time (<1 ns), while low incremental surge resistance enables effective energy diversion during sub-microsecond transients.
The device is rated for 600 W peak pulse power (10/1000 µs), derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surges at 0.01 % duty cycle. Thermal resistance is 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads), enabling reliable operation without heatsinking in typical industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1 mA test current - defines precise voltage threshold where clamping initiates in either direction |
| VWM | 94.0 V - maximum continuous reverse stand-off voltage before leakage exceeds 1 µA; sets safe operating margin below clamping |
| VC @ IPPM | 152 V at 3.9 A - clamped voltage seen by protected circuit during full-rated 600 W transient, limiting stress to downstream components |
| PPPM | 600 W - peak transient power dissipation capability under standardized 10/1000 µs waveform, validated for repetitive use at 0.01 % duty cycle |
| TJ max | +150 °C - maximum junction temperature; allows operation in high-ambient environments like industrial motor drives or outdoor telecom enclosures |
| Package | SMB (DO-214AA) - surface-mount outline with 0.220" × 0.130" footprint, compatible with automated placement and reflow soldering per J-STD-020 |
| MSL Level | Level 1 - no floor life limitation; can be stored indefinitely at ≤30 °C/60 % RH without baking prior to assembly |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; polarity-unmarked for bidirectional operation - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; either terminal functions identically as anode or cathode depending on instantaneous voltage polarity - enables single-device protection of AC or floating nodes |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Handles high-energy transients from relay switching or lightning-induced surges without degradation, supporting industrial-grade reliability |
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term parameter stability under thermal cycling |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for global electronics manufacturing without compromising electrical performance |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection margin for sensitive ICs |
| MSL Level 1, 260 °C lead-free reflow compatible | Eliminates pre-bake requirements and supports standard SMT assembly processes without moisture-related yield loss |
Applications
| Industrial Sensor Interface Protection | Telecom Line Card Surge Suppression |

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 VBR range (105–116 V), identical SMB package, but rated for 600 W with tighter VC spec (152 V max vs. 152 V typ); slightly higher IPPM (4.0 A) | Designed for broader industrial temperature range (−65 to +175 °C); preferred where extended high-temp operation is required | Select SMBJ110CA-T if operating ambient exceeds 150 °C or if tighter VC distribution is critical for margin-sensitive designs |
| 1.5SMC110CA | Higher power rating (1500 W), larger SMC (DO-214AB) package (0.315" × 0.220"), same VBR/VC specs; 3× footprint area | Used where higher single-pulse energy absorption is needed (e.g., primary-side AC input protection), not suitable for space-constrained layouts | Choose 1.5SMC110CA only when PCB layout allows larger footprint and system-level transients exceed 600 W capability of P6SMB110CA-M3/52 |
Compared with SMBJ110CA-T and 1.5SMC110CA, the P6SMB110CA-M3/52 offers optimal balance of compact SMB footprint, 600 W capability, halogen-free compliance, and commercial-grade cost-making it ideal for mid-power signal-line protection where board space and environmental compliance are prioritized over extreme thermal or energy margins.

FAQ
What is the clamping voltage of P6SMB110CA-M3/52 at its rated peak pulse current?
The P6SMB110CA-M3/52 has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 3.9 A under the 10/1000 µs waveform. This value is measured across both terminals in either polarity due to its bidirectional construction, ensuring predictable overvoltage limiting for protected circuits during transient events.
Is P6SMB110CA-M3/52 suitable for automotive applications?
The P6SMB110CA-M3/52 is a commercial-grade variant and is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB110CAHM3_B/H or P6SMB110CAHM3_B/I variants (with HM3_B or HM3_I suffixes), which include AEC-Q101 qualification, enhanced testing, and automotive traceability. The P6SMB110CA-M3/52 itself is intended for industrial, telecom, and consumer applications.
What does the "CA" suffix indicate in P6SMB110CA-M3/52?
The "CA" suffix in P6SMB110CA-M3/52 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both voltage polarities. Unlike unidirectional "A" versions, the CA variant has no cathode marking and functions identically regardless of terminal orientation, making it ideal for AC signal lines, differential buses, or floating ground systems.
How does the M3 suffix affect the P6SMB110CA-M3/52 material composition?
The "M3" suffix indicates that the P6SMB110CA-M3/52 is halogen-free and RoHS-compliant, with molding compound and plating meeting JEDEC J-STD-20 and JESD201 Class 2 whisker resistance requirements. It uses matte tin-plated leads and UL 94 V-0 compliant encapsulant - satisfying strict environmental mandates without sacrificing electrical or thermal performance.
Can P6SMB110CA-M3/52 be used in place of a unidirectional TVS like P6SMB110A-M3/52?
No - the P6SMB110CA-M3/52 is bidirectional and lacks polarity marking, while P6SMB110A-M3/52 is unidirectional with a cathode band. Substituting them requires circuit review: the CA version may conduct during normal forward bias in DC-coupled paths, whereas the A version blocks in one direction. Use P6SMB110CA-M3/52 only where true bidirectional clamping is required and DC bias is absent or symmetrical.
