Product details
Overview
P6SMB100 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a breakdown voltage range of 90–110 V, stand-off voltage of 81.0 V, and clamping voltage of 144 V at 4.3 A peak pulse current. It delivers fast response (<1.0 ps), low leakage (<1 µA @ 81 V), and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive electronics protection.
For engineers reviewing the P6SMB100 datasheet, P6SMB100 pinout, P6SMB100 application, or P6SMB100 equivalent, this device is selected for robust overvoltage protection in DC power rails where precise clamping, high surge immunity, and SMB footprint compatibility are required - especially in switching mode power supplies, adapters, and display subsystems.
Technical Context
The P6SMB100 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (90 V) at 1 mA test current. Its clamping action limits transient-induced voltage to ≤144 V under 10/1000 µs waveform, enabling reliable protection of downstream 100 V-rated components.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, supporting continuous operation up to TJ = 150 °C. Forward voltage is specified at 5.0 V @ 50 A - consistent across all P6SMB100–P6SMB220 variants per manufacturer note.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90 V / 110 V - defines guaranteed avalanche initiation window at 1 mA; ensures predictable turn-on before system damage threshold |
| VWM | 81.0 V - maximum continuous reverse operating voltage; sets safe DC rail margin below breakdown |
| VC @ IPPM | 144 V @ 4.3 A - clamped voltage during 10/1000 µs surge; determines protected circuit's peak stress level |
| PPPSM | 600 W - non-repetitive peak pulse power rating; quantifies single-event surge energy handling capability |
| IR @ VWM | <1 µA - ultra-low reverse leakage at stand-off voltage; minimizes standby power loss and signal path loading |
| TJ max | +150 °C - maximum junction temperature; enables use in high-ambient industrial and automotive under-hood environments |
| Package | DO-214AA (SMB) - standardized surface-mount outline with 0.090 g mass; compatible with automated pick-and-place and reflow |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band; meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (non-banded end) | Forward conduction terminal | Connects to lower-potential side of protected line; carries full forward surge current (IFSM = 100 A) |
| Cathode (banded end) | Avalanche clamping terminal | Connects to higher-potential side; sinks transient current into ground or return path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 144 V max clamping at 4.3 A IPPM ensures downstream ICs rated for 150 V rail remain within safe operating area |
| Response speed | <1.0 ps rise time enables suppression of nanosecond-scale ESD and fast transients before propagation |
| Leakage control | <1 µA reverse leakage at 81 V minimizes quiescent current draw in battery-powered or low-power systems |
| Automated assembly support | Low-profile DO-214AA package with J-STD-002 solderable terminals enables high-yield SMT production |
| Environmental compliance | RoHS-compliant and halogen-free per IEC 61249-2-21; moisture sensitivity level 1 per J-STD-020 |
Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Protection of primary-side MOSFETs and secondary-side rectifiers against input line surges and transformer flyback spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed across DC bus or output rail to clamp transient overvoltage before it reaches power stage components. Use Value: With 144 V clamping and 600 W surge rating, P6SMB100 prevents destructive voltage overshoot on 81 V nominal rails during 10/1000 µs transients. |

IC Role / Device Role / Timing Role: Standoff-rated TVS connected between L/N and earth or across bulk capacitor to absorb differential-mode surges. Use Value: 81.0 V stand-off voltage provides sufficient margin above 72 V peak rectified input while maintaining fast clamping response. |
| Television Power Boards | Monitor Backlight Drivers |

IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing repetitive line disturbances and load-dump events in consumer-grade mains-powered equipment. Use Value: 150 °C max junction temperature and 55 °C/W RθJA allow stable operation in thermally constrained TV chassis without derating. |
Use Scenario: Output rail protection in CCFL or LED backlight drivers where boost converter transients threaten driver ICs and LEDs. IC Role / Device Role / Timing Role: Clamping device placed across high-voltage boost output to limit overshoot during dimming transitions or open-circuit faults. Use Value: 90–110 V VBR range aligns with typical 100 V-class backlight outputs, ensuring reliable triggering before LED string overvoltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Bidirectional variant; VBR = 111–123 V; VC = 162 V @ 3.7 A; same SMB package | Supports AC-coupled or bidirectional signal lines; not suitable for unidirectional DC rail protection without polarity redesign | Select only if bipolar surge immunity (e.g., data lines, RS-485) is required; otherwise P6SMB100 offers tighter VBR tolerance and lower clamping |
| 1.5SMC100A | Higher power (1500 W); larger DO-214AB (SMC) package; VC = 165 V @ 9.1 A; VWM = 85.5 V | Used in high-energy industrial motor drives or telecom power; requires PCB layout change due to larger footprint | Choose when surge energy exceeds 600 W capability; avoid for space-constrained consumer designs where SMB fit is mandatory |
Compared with SMBJ100A and 1.5SMC100A, the P6SMB100 provides optimal balance of clamping precision (144 V), compact SMB footprint, and 600 W rating for cost-sensitive DC power rail protection - making it preferred for adapters, SMPS, and display power boards where board space and thermal constraints are critical.

FAQ
What is the breakdown voltage range for P6SMB100?
The P6SMB100 has a guaranteed breakdown voltage range of 90 V to 110 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures reliable and repeatable avalanche turn-on behavior across manufacturing lots and temperature extremes, directly supporting design margin calculations for 81 V stand-off applications.
Is P6SMB100 unidirectional or bidirectional?
P6SMB100 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its forward voltage specification (VF = 5.0 V @ 50 A). It must be oriented with cathode toward the higher-potential side of the protected line to function correctly - unlike bidirectional variants such as P6SMB100CA.
What is the clamping voltage of P6SMB100 under standard surge conditions?
The P6SMB100 clamps to a maximum of 144 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 4.3 A. This value is measured per Fig.3 in the datasheet and defines the upper voltage limit imposed on protected circuitry during transient events.
Does P6SMB100 meet automotive surge standards?
Yes, the P6SMB100 meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for 12 V and 24 V automotive power network protection. Its 150 °C junction rating and low leakage also support under-hood and infotainment module deployment.
What is the thermal resistance from junction to ambient for P6SMB100?
The P6SMB100 has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad on FR-4 PCB and is used to calculate allowable power dissipation at elevated ambient temperatures.
