Product details
Overview
P6SMB130 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 117–143 V, clamping voltage of 187 V at 3.3 A peak pulse current, and DO-214AA (SMB) package. It protects 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 P6SMB130 datasheet, P6SMB130 pinout, P6SMB130 application, or P6SMB130 equivalent, key selection criteria include its 105 V standoff voltage, <1 µA reverse leakage at VWM, 1.0 ps response time, junction temperature rating of –55°C to +150°C, and compliance with RoHS and halogen-free standards.
Technical Context
The P6SMB130 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage of 117 V at 1 mA test current. Its glass-passivated junction ensures stable clamping performance under repetitive transients, and its thermal resistance (RθJA = 55°C/W) supports operation up to 150°C junction temperature.
Designed for automotive and industrial power-line protection, it meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a (battery disconnect), Pulse 2b (alternator load dump), and Pulse 3a/3b (capacitive coupling) waveforms. Its 10/1000 µs surge rating delivers 600 W non-repetitive peak pulse power with fast sub-picosecond response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 117 V / 143 V - Ensures reliable triggering above 105 V operating rail while avoiding false trips |
| VWM | 105 V - Maximum continuous reverse working voltage compatible with 120 VAC-derived DC rails |
| VC @ IPPM | 187 V - Clamped voltage during 3.3 A 10/1000 µs surge, limiting downstream stress |
| PPPSM | 600 W - Peak pulse power handling for transient suppression without failure |
| IR @ VWM | <1 µA - Negligible leakage current preserves efficiency in high-impedance monitoring circuits |
| TJ max | +150 °C - Enables use in enclosed power supplies and under-hood automotive environments |
| Response time | <1.0 ps - Sub-nanosecond turn-on prevents voltage overshoot during fast ESD events |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode band marking. Matte tin-plated leads meet J-STD-002 solderability; moisture sensitivity level 1 per J-STD-020.

| Cathode | Clamp/Return side | Connected to ground or low-impedance return path; avalanche conduction occurs here during overvoltage |
Key Features
| Feature | Design Value |

Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Input rectifier output rail protection in offline flyback converters. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed across bulk capacitor to absorb line surges and inductive kickback. Use Value: Limits transient voltage to ≤187 V, preventing MOSFET gate oxide rupture and controller IC latch-up. | Use Scenario: Secondary-side DC output protection in universal-input wall adapters. IC Role / Device Role / Timing Role: Standoff-rated TVS on regulated 12 V or 24 V output to suppress coupling noise and ESD from connected devices. Use Value: Maintains <1 µA leakage at 105 V, avoiding regulation drift while clamping 600 W surges within safe margins. |
| Flat Panel TV Power Board | Industrial Monitor Backlight Driver |
Use Scenario: Protection of main 24 V/48 V logic and backlight supply rails against ESD from HDMI/USB ports. IC Role / Device Role / Timing Role: Primary-level TVS on board-level power distribution network upstream of DC-DC converters. Use Value: Sub-1 ps response prevents voltage overshoot from propagating into sensitive video processing ICs. | Use Scenario: Surge suppression on CCFL or LED driver high-voltage boost outputs (e.g., 100–200 V). IC Role / Device Role / Timing Role: Clamp device placed between boost converter output and lamp connector to absorb open-circuit transients. Use Value: 187 V clamping voltage ensures lamp driver FETs remain within 80% of absolute maximum VDSS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 130 V bidirectional variant; VBR = 144–156 V; VC = 219 V @ 2.7 A; same SMB package | Supports AC-coupled or floating signal lines; not suitable for DC-rail-only unidirectional clamping | Select SMBJ130A only if bipolar surge immunity (e.g., RS-485 bus) is required; P6SMB130 offers lower clamping for DC rails. |
| 1.5SMC130A | Same VBR/VC specs but in larger DO-214AB (SMC) package; higher thermal mass; RθJA = 40°C/W | Better sustained power dissipation in high-ambient-temperature environments; requires larger PCB area | Choose 1.5SMC130A when board layout allows larger footprint and thermal management demands >55°C/W RθJA. |
Compared with SMBJ130A and 1.5SMC130A, the P6SMB130 provides optimal balance of low clamping voltage (187 V), compact SMB footprint, and unidirectional optimization for DC power rail protection-making it preferred for space-constrained SMPS and adapter designs where polarity is fixed.

FAQ
What is the breakdown voltage range of the P6SMB130?
The P6SMB130 has a guaranteed breakdown voltage range of 117 V to 143 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures robust triggering above its 105 V standoff voltage while accommodating process variation-critical for reliable overvoltage protection in 120 VAC-derived DC systems where the P6SMB130 is commonly deployed.
Is the P6SMB130 unidirectional or bidirectional?
The P6SMB130 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. It conducts only in reverse bias during overvoltage events and blocks forward current like a standard rectifier. For bidirectional protection, engineers must select P6SMB130C or P6SMB130CA-models explicitly rated for symmetrical surge suppression in AC or floating signal paths.
What is the maximum clamping voltage of the P6SMB130 under surge conditions?
The P6SMB130 clamps to a maximum of 187 V when subjected to its rated 3.3 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This clamping voltage defines the upper voltage limit imposed on protected circuitry during transients, ensuring downstream components such as MOSFETs and controllers remain within safe operating limits during ISO 7637-2 Pulse 1 or Pulse 2b events.
Does the P6SMB130 meet automotive surge immunity standards?
Yes, the P6SMB130 meets ISO 7637-2 requirements for Pulse 1 (inductive switch-off), Pulse 2a (battery disconnection), Pulse 2b (alternator load dump), and Pulse 3a/3b (capacitive coupling). Its 600 W peak pulse power rating, fast <1 ps response, and specified clamping behavior under defined waveforms make it suitable for front-end protection in automotive body control modules, infotainment power supplies, and ADAS camera modules where the P6SMB130 is used.
What is the thermal resistance and maximum junction temperature of the P6SMB130?
The P6SMB130 has a junction-to-ambient thermal resistance (RθJA) of 55°C/W and a maximum junction temperature (TJ) of +150°C. These values allow the P6SMB130 to operate reliably in enclosed power supplies and under-hood automotive environments without forced cooling, provided PCB copper area and ambient conditions align with its derating curve-key for long-term stability in applications where the P6SMB130 serves as primary surge defense.
