Product details
Overview
P4SMA130A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping fast transients in DC power lines. It features a 124–137 V breakdown voltage (VBR), 111 V working stand-off voltage (VWM), 179 V maximum clamping voltage (VC) at 2.3 A peak pulse current, and 400 W peak pulse power rating per 10/1000 µs waveform - used in on-board DC/DC converters and industrial adapters.
For engineers reviewing the P4SMA130A datasheet, P4SMA130A pinout, P4SMA130A application, or P4SMA130A equivalent, this page delivers verified electrical parameters, ISO 7637-2 compliance status, thermal derating behavior, junction temperature limits, and real-world clamping performance under standardized surge conditions.
Technical Context
The P4SMA130A operates as a unidirectional avalanche diode with glass-passivated junction, optimized for sub-nanosecond response (<1.0 ps) to ESD and load-dump transients. Its clamping action begins at VBR = 124–137 V (tested at 1.0 mA), sustaining up to 400 W peak pulse power without degradation when ambient temperature remains ≤25°C.
Thermal derating follows a linear curve above 25°C ambient, with full power rated only up to TA = 25°C and zero power at TA = 150°C. The device supports operating junction temperatures from –55°C to +150°C and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT | 124–137 V at 1.0 mA test current - defines minimum voltage at which avalanche conduction initiates reliably |
| VWM | 111 V - maximum continuous reverse voltage before significant leakage; ensures no false triggering during normal operation |
| VC @ IPPM | 179 V at 2.3 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak transient power dissipation capability under standard 10/1000 µs waveform |
| IR @ VWM | <1 µA - ultra-low reverse leakage preserves efficiency in high-impedance bias networks |
| TJ Range | –55°C to +150°C - enables deployment in automotive engine bays and industrial power supplies |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-diode configuration with cathode band marking. Matte tin-plated leads, UL 94V-0 molding compound, 0.060 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during forward surges or bias conditions |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential rail; enters avalanche breakdown when transient exceeds VWM, shunting energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| Fast response time <1.0 ps | Clamps ESD events before downstream ICs experience overvoltage damage |
| ISO 7637-2 Pulse 1/2a/2b/3a/3b compliant | Validated for automotive load-dump and inductive switching transient suppression |
| Moisture Sensitivity Level 1 | Enables standard SMT reflow without baking or special handling |
Applications
| Switching Mode Power Supply (SMPS) | On-board DC/DC Converter |
|---|---|
Use Scenario: Protects primary-side MOSFET gate drivers and secondary-side synchronous rectifiers from flyback spikes and cross-conduction transients. IC Role / Device Role: Unidirectional TVS placed across input/output rails to clamp voltage overshoot during switching transitions. Use Value: Limits VC to 179 V, preventing breakdown of 200 V-rated FETs and maintaining system uptime under repetitive 400 W surges. | Use Scenario: Shields point-of-load regulators in telecom base stations from board-level ESD and hot-swap inrush transients. IC Role / Device Role: Standoff protection element between input bus and converter input capacitor, absorbing 10/1000 µs pulses up to 2.3 A. Use Value: Maintains VWM = 111 V margin below nominal 12 V or 24 V rails, enabling robust operation without false triggering. |
| Industrial Adapter | Lighting Application |
Use Scenario: Safeguards AC/DC adapter output stages against lightning-induced surges conducted via mains input or output cables. IC Role / Device Role: Secondary-side clamping diode across output terminals, triggered only during overvoltage events exceeding 111 V. Use Value: Withstands 400 W peak power without thermal runaway, supporting CE-compliant surge immunity up to 2 kV (line-earth). | Use Scenario: Protects LED driver ICs and MOSFETs in streetlight controllers exposed to outdoor voltage transients and ESD during maintenance. IC Role / Device Role: Bidirectional-capable variant not used; unidirectional P4SMA130A applied across constant-current output to suppress positive-going spikes. Use Value: Leverages 1 µA max leakage at 111 V to avoid loading precision current-sense circuits while delivering 179 V clamping under 2.3 A surge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | DO-214AA (SMB) package; same VBR range (124–137 V), but 600 W PPPM; larger footprint and higher thermal mass | Preferred where PCB space allows and higher surge margin is required beyond 400 W | Select SMBJ130A if layout permits larger SMA-equivalent footprint and system requires >400 W surge headroom |
| 1.5SMC130A | DO-214AB (SMC) package; identical VBR/VWM/VC, but 1500 W PPPM; 2× footprint area and 3× thermal mass vs. P4SMA130A | Suitable for high-reliability industrial power supplies needing multi-pulse endurance | Choose 1.5SMC130A when surge duty cycle exceeds single-event assumptions and board space accommodates SMC outline |
Compared with SMBJ130A and 1.5SMC130A, the P4SMA130A offers optimal balance of compact DO-214AC footprint, 400 W surge rating, and low-profile mounting - ideal for space-constrained adapters and DC/DC modules where thermal mass is managed via copper pour and airflow.

FAQ
What is the breakdown voltage range of the P4SMA130A?
The P4SMA130A has a specified breakdown voltage (VBR) range of 124 V to 137 V, measured at 1.0 mA test current per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across production lots and supports design margining for 130 V nominal systems. The P4SMA130A achieves tight VBR tolerance via glass-passivated junction processing.
Does the P4SMA130A meet automotive transient standards?
Yes, the P4SMA130A meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive electrical disturbances. Its 400 W peak pulse power rating and sub-1.0 ps response time enable reliable suppression of load-dump and inductive switching transients in 12 V and 24 V vehicle subsystems. The P4SMA130A is not AEC-Q200 qualified but is widely deployed in non-safety-critical automotive modules.
What is the maximum clamping voltage of the P4SMA130A under surge conditions?
The P4SMA130A exhibits a maximum clamping voltage (VC) of 179 V when subjected to a 10/1000 µs surge waveform at 2.3 A peak current. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum ratings. The P4SMA130A maintains this clamping performance across its full operating temperature range.
Is the P4SMA130A RoHS and halogen-free compliant?
Yes, the P4SMA130A is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and matte tin-plated leads comply with J-STD-002 solderability requirements. These certifications confirm suitability for environmentally regulated markets including EU, Japan, and China. The P4SMA130A carries no substance-of-concern exemptions under current RoHS Annex II.
What is the thermal derating behavior of the P4SMA130A above 25°C ambient?
The P4SMA130A follows a linear thermal derating curve: peak pulse power drops from 400 W at 25°C ambient to zero at 150°C ambient. Derating is defined per Figure 2 in the official datasheet, with ~2.67 W/°C reduction slope. This behavior must be factored into designs operating in enclosed enclosures or near heat sources. The P4SMA130A's junction-to-ambient thermal resistance is not specified, but its DO-214AC package relies on PCB copper area for effective heat dissipation.
