Product details
Overview
P6SMB100A-M3/52 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 maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). 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-M3/52 datasheet, P6SMB100A-M3/52 pinout, P6SMB100A-M3/52 application, or P6SMB100A-M3/52 equivalent, key selection criteria include unidirectional polarity, 85.5 V VWM tolerance, 1.0 mA test current (IT), 1.0 μA reverse leakage at VWM, and halogen-free RoHS-compliant M3 suffix construction suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance standby to low-impedance conduction when reverse voltage exceeds its breakdown threshold (VBR = 95.0–105 V at 1.0 mA). Its glass-passivated junction ensures stable avalanche behavior under repetitive 10/1000 μs surge events at 0.01% duty cycle.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 5.0 mm × 5.0 mm copper pads) and RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C with 5.0 W steady-state power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transient overvoltage. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per single 10/1000 μs waveform; validates robustness against IEC 61000-4-5 surges. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal standby current; preserves low-power system integrity and avoids false triggering. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in enclosed industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with JEDEC J-STD-020 MSL Level 1 reflow profiles. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line; establishes polarity-dependent clamping direction. |
| Cathode | Avalanche conduction terminal / Clamping output | Connected to higher-potential side (e.g., VBUS); conducts surge current to ground when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Validates compliance with IEC 61000-4-5 Level 4 surge immunity requirements for industrial interfaces. |
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics across temperature and lifetime; eliminates parameter drift. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration standards and automotive supply chain sustainability mandates. |
| MSL Level 1 moisture sensitivity | Enables direct placement without baking; supports standard reflow profiles up to 260 °C peak. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/52 | Same VWM (85.5 V), VC (137 V), and PPPM (600 W), but in smaller SMA (DO-214AC) package with RθJA = 140 °C/W. | Lower thermal mass limits sustained surge repetition rate; unsuitable for high-duty-cycle industrial motor drives. | Select when board space is constrained and thermal derating is acceptable. |
| 1.5SMC100A | Identical electrical specs but in larger SMC (DO-214AB) package with RθJA = 60 °C/W and 1.5 kW peak power rating. | Higher thermal inertia enables repeated surges without junction overheating; requires 30% more PCB area. | Select for mission-critical telecom infrastructure where thermal reliability outweighs footprint. |
Compared with SMAJ100A-E3/52, P6SMB100A-M3/52 offers superior thermal management (RθJA = 100 vs. 140 °C/W) and halogen-free compliance; versus 1.5SMC100A, it delivers identical protection in 40% less board area while trading off ultimate surge repetition capability for compactness.

FAQ
What is the maximum clamping voltage of the P6SMB100A-M3/52 under a 10/1000 μs surge?
The P6SMB100A-M3/52 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A using the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads), and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB100A-M3/52 maintains this clamping performance across its full operating temperature range.
Is the P6SMB100A-M3/52 suitable for automotive applications?
The P6SMB100A-M3/52 is halogen-free and RoHS-compliant but not AEC-Q101 qualified; its base ordering code uses the M3 suffix, not HM3_X. For automotive-grade use, Vishay specifies variants like P6SMB100AHM3_B/H, which include additional qualification testing. The P6SMB100A-M3/52 remains appropriate for non-safety-critical industrial and telecom systems where AEC-Q101 is not mandated.
How does the M3 suffix differ from the E3 suffix in P6SMB100A-M3/52?
The M3 suffix indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, whereas E3 denotes standard RoHS compliance without halogen-free assurance. Both meet J-STD-020 MSL Level 1, but P6SMB100A-M3/52 satisfies stricter environmental requirements for green electronics manufacturing. The P6SMB100A-M3/52 shares identical electrical specs with its E3 counterpart.
What is the reverse leakage current of the P6SMB100A-M3/52 at its stand-off voltage?
The P6SMB100A-M3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated stand-off voltage (VWM) of 85.5 V and tested at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and avoids unnecessary power loss in battery-operated equipment. The P6SMB100A-M3/52 maintains leakage below 5.0 μA up to TJ = 125 °C per datasheet derating curves.
Can the P6SMB100A-M3/52 be used in bidirectional configurations?
No - the P6SMB100A-M3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P6SMB100CA-M3/52), which lacks polarity marking and provides symmetrical clamping in both directions. Using P6SMB100A-M3/52 in reverse-biased configurations risks permanent damage due to forward conduction beyond its 100 A IFSM rating. Always verify polarity alignment before PCB layout.
