Product details
Overview
P6SMB100A-E3/52 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 = 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-E3/52 datasheet, P6SMB100A-E3/52 pinout, P6SMB100A-E3/52 application, or P6SMB100A-E3/52 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 clamping device in parallel with sensitive circuit nodes, conducting only when reverse voltage exceeds its breakdown threshold (VBR min = 95.0 V, max = 105 V at 1.0 mA). Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance.
Designed for transient suppression-not steady-state regulation-it responds in <1 ps to overvoltage events and sustains repetitive 10/1000 μs pulses at 0.01% duty cycle. Thermal resistance is 100 °C/W junction-to-ambient (RθJA) on standard 0.2" × 0.2" copper pads, limiting continuous power dissipation to 5.0 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping onset |
| VBR (Breakdown Voltage) | 95.0–105 V at 1.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on above system nominal rail |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability per single 10/1000 μs transient event |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal parasitic loading on DC bias networks during normal operation |
| TJ max | 150 °C - Maximum junction temperature; enables use in high-ambient industrial environments with derating |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated placement; 0.220" × 0.130" body size |
Pinout & Package
Package: SMB (DO-214AA), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode indicated by band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-potential node; completes conduction path during reverse transient |
| Cathode | High-side connection point | Connected to protected line (e.g., 48 V rail); carries full surge current into ground via anode |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection of 24–48 V industrial buses against IEC 61000-4-5 Level 3 surges without external series impedance |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on downstream silicon-critical for 100 V-rated MOSFET gate drivers and op-amps |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT assembly without pre-baking or special handling |
| Glass-passivated junction | Ensures long-term stability of breakdown voltage and leakage across temperature and lifetime cycling |
| AEC-Q101 qualification option (HE3/HM3 suffix) | Validates robustness for automotive power modules where P6SMB100A-E3/52 serves as secondary rail protector |
Applications
| Industrial Motor Drive DC Bus | Telecom PoE+ Power Interface |
|---|---|
|
Use Scenario: Protection of 48 V DC bus against back-EMF spikes from brushed DC motor commutation and contactor switching. IC Role / Device Role / Timing Role: Unidirectional TVS placed across bus rails to clamp transients before they reach DC-DC controllers and gate drivers. Use Value: Limits voltage excursion to ≤137 V, preventing damage to 100 V-rated Si MOSFETs and maintaining functional safety integrity. |
Use Scenario: Surge suppression on IEEE 802.3at PoE+ power sourcing equipment (PSE) output ports exposed to cable-induced lightning surges. IC Role / Device Role / Timing Role: Primary transient shunt on 57 V maximum PoE+ output, coordinated with upstream gas discharge tube (GDT). Use Value: Clamps fast-rising transients within nanoseconds while sustaining 600 W peak power-meeting IEC 61000-4-5 2 Ω/12 Ω coupling requirements. |
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|
Use Scenario: Secondary overvoltage protection on 12 V/24 V supply rails feeding microcontrollers and CAN transceivers in BCMs. IC Role / Device Role / Timing Role: Standby clamping device activated only during load dump or jump-start events exceeding 85.5 V. Use Value: Complements primary TVS with higher power rating; provides redundancy without adding capacitance that would distort CAN signal edges. |
Use Scenario: Protection of 0–10 V or 4–20 mA analog input front-ends in programmable logic controllers subjected to field wiring faults and ESD. IC Role / Device Role / Timing Role: Low-leakage (1.0 μA) shunt element placed before precision amplifier inputs to prevent latch-up. Use Value: Maintains signal integrity with negligible DC error (<0.1 μA offset contribution) while surviving 4 kV EFT bursts per IEC 61000-4-4. |
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 | 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 compliance | Select when cost sensitivity outweighs peak surge margin and clamping tightness |
| 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; requires larger PCB pad area and may not fit space-constrained layouts | Choose for high-repetition-rate surge environments where junction temperature rise must be minimized |
Compared with SMAJ100A and 1.5SMC100A, P6SMB100A-E3/52 delivers optimal balance of compact SMB footprint, 600 W surge capacity, and 137 V clamping-making it preferred for space-limited 48 V industrial and telecom systems requiring certified transient immunity.

FAQ
What is the maximum clamping voltage of P6SMB100A-E3/52 under surge conditions?
The P6SMB100A-E3/52 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 standard test conditions in the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024) and represents the highest voltage imposed on the protected circuit during worst-case transient events.
Is P6SMB100A-E3/52 RoHS-compliant and halogen-free?
Yes, P6SMB100A-E3/52 carries the "E3" suffix, indicating it is RoHS-compliant and commercial grade. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P6SMB100A-M3/52) must be selected. Both meet JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.
Can P6SMB100A-E3/52 be used in bidirectional configurations?
No, P6SMB100A-E3/52 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional operation, the equivalent part is P6SMB100CA, which uses the "CA" suffix and has no polarity marking. The two are not interchangeable without circuit redesign.
What is the thermal resistance of P6SMB100A-E3/52, and how does it affect layout?
P6SMB100A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must adhere to this minimum pad area; reducing pad size increases RθJA and risks thermal runaway during high-duty-cycle transients.
Does P6SMB100A-E3/52 meet AEC-Q101 qualification?
No, P6SMB100A-E3/52 is not AEC-Q101 qualified. That qualification applies only to variants with "HE3" or "HM3" suffixes (e.g., P6SMB100AHE3_B/H). The "E3/52" version is commercial-grade and intended for industrial and telecom applications where automotive reliability certification is not required.
