Product details
Overview
P6SMB100A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 85.5V, breakdown voltage range of 95–105V, and clamping voltage of 137V at 4.5A peak pulse current. It protects DC power rails in switching mode power supplies, adapters, and display electronics against ESD and surge events per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the P6SMB100A datasheet, P6SMB100A pinout, P6SMB100A application, or P6SMB100A equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, 1μA max reverse leakage at VWM, 1.0ps response time, and thermal resistance (RθJA = 55°C/W) for board-level thermal design.
Technical Context
The P6SMB100A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (95V) under 1mA test current. Its glass-passivated junction ensures stable clamping performance and low leakage (<1μA at 85.5V), while the 10/1000μs waveform-rated 600W peak pulse power supports automotive and industrial surge immunity requirements.
Designed for surface-mount assembly on PCBs with standard SMB footprints, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band, and moisture sensitivity is rated Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 95 V / 105 V - Breakdown voltage range at 1 mA test current; defines turn-on threshold tolerance |
| VC @ IPPM | 137 V - Clamped voltage at 4.5 A peak pulse current; determines protected circuit's max overvoltage stress |
| PPPSM | 600 W - Non-repetitive peak pulse power handling (10/1000 μs waveform); sets surge energy limit |
| IR @ VWM | <1 μA - Reverse leakage at standoff voltage; critical for low-power standby circuits |
| TJ max | 150 °C - Maximum junction temperature; constrains thermal design margin in high-ambient environments |
| RθJA | 55 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under steady-state power dissipation |

| Environmental compliance | RoHS-compliant and halogen-free per IEC 61249-2-21; meets UL 94V-0 flammability rating |
Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapter |
|---|---|
Use Scenario: Input rectifier output rail in offline SMPS subjected to line surges and load dump transients. IC Role / Device Role: Unidirectional TVS placed between DC bus and ground to clamp positive-going transients. Use Value: Limits voltage excursion to ≤137 V during 600 W surges, protecting primary-side controllers and MOSFETs rated for 200 V breakdown. | Use Scenario: Secondary-side 12 V or 24 V DC output rail exposed to capacitive coupling and ESD from connected peripherals. IC Role / Device Role: Standoff-rated TVS suppressing fast transients before they reach USB ports or microcontroller I/O. Use Value: Sub-1 μA leakage preserves low-load efficiency; 137 V clamping prevents latch-up in 3.3 V/5 V logic interfaces downstream. |
| Television Power Board | Monitor Backlight Inverter |
Use Scenario: Main 12–24 V supply rail feeding audio amplifiers and video processing ICs in flat-panel TVs. IC Role / Device Role: Primary overvoltage suppression device on main DC distribution net. Use Value: Withstands repetitive ISO 7637-2 Pulse 2b (inductive switch-off) events without degradation; RθJA = 55°C/W allows operation up to 85°C ambient. | Use Scenario: High-voltage boost rail (≈300 V) in CCFL or LED backlight inverters subject to transformer ringing and arc-induced spikes. IC Role / Device Role: Secondary-stage TVS on auxiliary bias winding or feedback path. Use Value: 95–105 V VBR range provides precise threshold alignment with 100 V-rated gate drivers; glass passivation ensures long-term reliability under thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same DO-214AA package, identical VWM/VBR/VC specs, but from STMicroelectronics; RθJA = 50°C/W (slightly better thermal performance) | Valid for same PCB footprint and surge profiles; preferred where tighter thermal margin is required | Select SMBJ100A if board-level thermal simulation shows junction temperature exceeding 135°C under worst-case ambient + power dissipation |
| 1.5SMC100A | Higher power rating (1500 W), larger DO-214AB (SMC) package; VWM = 85.5 V, VC = 154 V at 9.7 A | Requires PCB layout change; suited for higher-energy surge environments (e.g., industrial motor drives) | Choose 1.5SMC100A only when tested surge waveforms exceed 600 W capability or require >10 A peak pulse current handling |
Compared with SMBJ100A and 1.5SMC100A, the P6SMB100A offers optimal balance of compact SMB footprint, 600 W surge capacity, and sub-1 μA leakage-making it ideal for space-constrained consumer power supplies where thermal headroom and standby efficiency are prioritized over extreme surge margin.

FAQ
What is the maximum clamping voltage of the P6SMB100A under standard test conditions?
The P6SMB100A has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.5 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry will not experience more than 137 V during defined surge events, making the P6SMB100A suitable for safeguarding 100 V-rated components.
Is the P6SMB100A unidirectional or bidirectional, and how is polarity identified?
The P6SMB100A is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. Polarity is marked by a cathode band on the DO-214AA package body; the banded end connects to the protected line, while the anode connects to ground. This configuration suppresses only positive-going transients relative to ground.
Does the P6SMB100A meet automotive surge immunity standards?
Yes, the P6SMB100A meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a (sudden load release), Pulse 2b (supply interruption), Pulse 3a (capacitive coupled noise), and Pulse 3b (ground bounce). Its 600 W rating and 137 V clamping voltage align with Level III/IV test profiles commonly applied to infotainment and body-control module power inputs.
What is the thermal resistance and maximum junction temperature specification for the P6SMB100A?
The P6SMB100A has a junction-to-ambient thermal resistance (RθJA) of 55°C/W and a maximum junction temperature (TJ) of 150°C. These values assume standard PCB mounting on FR-4 with minimum copper area; actual thermal performance depends on board layout, copper pour, and airflow. The P6SMB100A must be derated above 25°C ambient per the manufacturer's pulse derating curve.
Can the P6SMB100A be used in place of the P6SMB100 without redesigning the PCB?
Yes, the P6SMB100A is a direct replacement for the P6SMB100 in the same DO-214AA package, with identical pinout and mechanical dimensions. However, the P6SMB100A offers tighter VBR tolerance (95–105 V vs. 90–110 V) and lower clamping voltage (137 V vs. 144 V), resulting in improved protection margin. No PCB changes are required, and the P6SMB100A enhances system robustness without layout modification.
