Product details
Overview
P6SMB150 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 135–165 V, stand-off voltage of 121 V, and clamping voltage of 215 V at 2.9 A peak pulse current. It protects power rails in switching mode power supplies and adapters against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB150 datasheet, P6SMB150 pinout, P6SMB150 application, or P6SMB150 equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, 150°C max junction temperature, <1 µA leakage at 121 V, sub-1 ps response time, and compliance with automotive surge immunity standards.
Technical Context
The P6SMB150 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 135–165 V breakdown range under 1 mA test current. Its glass-passivated junction ensures stable clamping performance and low leakage (<1 µA at VWM = 121 V).
Thermally, it features a junction-to-case resistance of 10°C/W and junction-to-ambient resistance of 55°C/W, enabling reliable operation up to 150°C junction temperature. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 135 V / 165 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current |
| VWM | 121 V - maximum continuous reverse operating voltage before significant leakage occurs |
| VC @ IPPM | 215 V at 2.9 A - clamped voltage during 10/1000 µs surge, limiting downstream voltage stress |
| PPPM | 600 W - non-repetitive peak pulse power handling per 10/1000 µs waveform |
| ID @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +150 °C - enables use in thermally demanding environments like enclosed power adapters |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 0.090 g mass and matte tin-plated leads |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking; terminals are matte tin-plated for solderability per J-STD-002; polarity is marked on body.

Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Protects primary-side DC bus and secondary-side output rails from load-dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed across input/output capacitors to limit voltage overshoot during surge events. Use Value: Clamps to 215 V at 2.9 A, preventing MOSFET or controller IC damage while maintaining 121 V steady-state operation. | Use Scenario: Shields low-voltage DC outputs (e.g., 12 V, 19 V) from coupling noise and external surges entering via AC mains or USB-C PD negotiation. IC Role / Device Role / Timing Role: Standoff-rated TVS on secondary-side output to absorb repetitive 10/1000 µs pulses without degradation. Use Value: Sub-1 µA leakage at 121 V ensures no measurable impact on no-load efficiency or standby power consumption. |
| Flat Panel TV Power Board | Monitor Backlight Inverter |
Use Scenario: Safeguards main 24 V or 48 V logic and backlight power rails against ESD and cable discharge events during field service or hot-plug operations. IC Role / Device Role / Timing Role: Primary-level transient suppressor mounted near input connector and bulk capacitor. Use Value: 600 W peak power rating handles multiple ISO 7637-2 Pulse 1 events without parametric shift or failure. | Use Scenario: Protects CCFL or LED driver ICs from voltage spikes generated by transformer flyback or lamp ignition arcs. IC Role / Device Role / Timing Role: Fast-clamping TVS placed across driver output stage to limit reflected surge voltage. Use Value: 215 V clamping voltage ensures driver ICs rated for 250 V abs max remain within safe operating area during worst-case transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | 150 V nominal breakdown (142.5–157.5 V), 600 W PPPM, same DO-214AA package | Lower VBR tolerance (±5% vs ±10% for P6SMB150), tighter clamping but higher cost | Select SMBJ150A where tighter VBR consistency is required for precision rail protection |
| 1.5SMC150A | Same VBR range (135–165 V), 600 W PPPM, but larger DO-214AB (SMC) package | Higher thermal mass improves surge endurance but requires larger PCB footprint | Choose 1.5SMC150A for high-volume industrial designs needing enhanced thermal margin and legacy board compatibility |
Compared with SMBJ150A and 1.5SMC150A, the P6SMB150 offers broader VBR tolerance and lower unit cost in the compact SMB outline, making it optimal for cost-sensitive consumer power supplies where ±10% breakdown variation is acceptable.

FAQ
What is the breakdown voltage range of the P6SMB150?
The P6SMB150 has a specified breakdown voltage (VBR) range of 135 V to 165 V at 1 mA test current, measured after 30 ms square-wave pulse application. This ±10% tolerance reflects manufacturing spread and ensures reliable triggering across temperature and lifetime, and is confirmed in TSC's Q2209 datasheet revision.
Is the P6SMB150 unidirectional or bidirectional?
The P6SMB150 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. Its cathode band marks the clamping terminal, and it conducts only during reverse overvoltage events. Bidirectional variants require explicit "C" (e.g., P6SMB150C) and exhibit symmetrical clamping in both polarities.
What is the maximum clamping voltage of the P6SMB150 under surge conditions?
The P6SMB150 clamps to a maximum of 215 V when subjected to its rated 2.9 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper limit of voltage seen by downstream components during transient events.
Does the P6SMB150 meet automotive surge immunity standards?
Yes, the P6SMB150 meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling noise), as explicitly stated in the TSC Q2209 datasheet. It is widely deployed in automotive-grade power modules and infotainment power supplies.
What is the thermal resistance of the P6SMB150?
The P6SMB150 has a junction-to-case thermal resistance (RθJC) of 10°C/W and junction-to-ambient resistance (RθJA) of 55°C/W, measured under standard JEDEC conditions. These values enable accurate thermal modeling for PCB layout and derating calculations in high-power-density applications.
