Product details
Overview
P4SMA130 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for robust overvoltage protection in DC power rails. It features a 105 V working stand-off voltage (VWM), 117–143 V breakdown voltage (VBR) at 1 mA, 187 V maximum clamping voltage (VC) under 2.2 A 10/1000 μs surge, 400 W peak pulse power rating, and operates from –55 °C to +150 °C junction temperature - deployed in on-board DC/DC converters and industrial SMPS inputs.
For engineers reviewing the P4SMA130 datasheet, P4SMA130 pinout, P4SMA130 application, or P4SMA130 equivalent, key selection criteria include clamping performance at rated surge current, leakage current below 1 µA at VWM, compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, moisture sensitivity level 1 handling, and UL 94V-0 mold compound - all verified for automotive-grade power rail protection.
Technical Context
The P4SMA130 is a single-die, unidirectional TVS diode optimized for fast transient suppression on low-to-medium voltage DC lines. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 105 V), while its sub-1 ps response time enables effective suppression of ESD and load-dump transients before downstream ICs are damaged.
It operates within a –55 °C to +150 °C junction temperature range and is rated for 400 W peak pulse power (10/1000 μs waveform) with derating above 25 °C ambient per Fig.2. The device meets ISO 7637-2 for automotive electrical disturbances and is halogen-free per IEC 61249-2-21.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same VWM (105 V), slightly lower VC (182 V @ 2.3 A), higher IPPM (2.3 A vs. 2.2 A), SMB package (larger footprint). | Higher surge current rating suits higher-energy transients; larger SMB package may require PCB redesign. | Select SMBJ130A when higher IPPM margin or legacy SMB layout compatibility is required. |
| 1.5SMC130A | Same VWM (105 V), identical VC (187 V @ 2.2 A), but 1.5 kW rating (vs. 400 W); DO-214AB (SMC) package (3.6 mm × 2.6 mm vs. SMA's 2.8 mm × 1.6 mm). | Higher power rating supports repeated surge exposure; larger SMC package increases board area usage. | Choose 1.5SMC130A for applications requiring multi-pulse endurance or where space allows larger package. |
Compared with SMBJ130A and 1.5SMC130A, the P4SMA130 delivers identical clamping performance in a smaller DO-214AC footprint and lower cost, making it optimal for space-constrained, single-pulse industrial and automotive power rails where 400 W peak rating suffices.

FAQ
What is the maximum clamping voltage of the P4SMA130 under standard surge conditions?
The P4SMA130 has a maximum clamping voltage (VC) of 187 V when subjected to a 10/1000 μs surge waveform with a peak current (IPPM) of 2.2 A. This value is measured per ANSI/IEEE C62.35 and represents the highest voltage that will appear across the P4SMA130 during such a transient event, ensuring downstream components remain within safe operating limits.
Is the P4SMA130 suitable for bidirectional transient protection?
No, the P4SMA130 is a unidirectional TVS diode intended for DC line protection with defined anode and cathode polarity. For bidirectional applications, the P4SMA130A variant (marked RFJ) or parts with 'C' or 'CA' suffixes must be used - these are explicitly rated for symmetrical clamping in both polarities per the datasheet's bipolar applications note.
What is the leakage current specification for the P4SMA130 at its working stand-off voltage?
The P4SMA130 exhibits a maximum reverse leakage current (IR) of 1 µA when biased at its working stand-off voltage (VWM) of 105 V and tested at 25 °C. This ultra-low leakage ensures minimal power loss and avoids interference with high-impedance monitoring circuits commonly found in precision power management systems using the P4SMA130.
Does the P4SMA130 meet automotive transient immunity standards?
Yes, the P4SMA130 meets ISO 7637-2 for automotive electrical disturbances, including Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery connection/disconnection), and Pulse 3a/3b (capacitive coupling). Its 400 W peak pulse rating, 187 V clamping, and 150 °C junction rating make it suitable for engine control unit (ECU) and body electronics power rail protection where the P4SMA130 is deployed.
What packaging and reel quantity is offered for the P4SMA130?
The P4SMA130 is supplied in DO-214AC (SMA) package format on tape-and-reel, with 7,500 units per reel. This packaging supports high-speed automated placement and complies with moisture sensitivity level 1 (MSL-1) per J-STD-020, eliminating bake requirements and enabling direct use in standard reflow processes without preconditioning - critical for consistent P4SMA130 integration into production lines.
