Product details
Overview
P4SMA160C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal paths. It features a 130 V working stand-off voltage, 144–176 V breakdown voltage at 1 mA, 230 V maximum clamping voltage under 10/1000 μs surge, 400 W peak pulse power rating, and DO-214AC (SMA) package - used in automotive infotainment power rails.
For engineers reviewing the P4SMA160C datasheet, P4SMA160C pinout, P4SMA160C application, or P4SMA160C equivalent, key selection criteria include clamping performance at 1.8 A peak impulse current, bidirectional polarity marking, compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and moisture sensitivity level 1 handling requirements.
Technical Context
The P4SMA160C is a unidirectional/bidirectional TVS diode configured as a single die in a DO-214AC package, with glass passivated junction for stable breakdown behavior. Its fast response time (<1.0 ps) enables suppression of ESD and fast transients before sensitive circuitry is damaged.
It operates across –55 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. The device exhibits <1 µA reverse leakage at 130 V and a temperature coefficient of VBR of 0.108 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR min/max | 144 V / 176 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during surges |
| VC@IPPM | 230 V at 1.8 A (10/1000 μs) - Clamping voltage limiting downstream component stress |
| PPPM | 400 W - Peak pulse power handling capability per single non-repetitive surge event |
| IR@VWM | <1 µA - Low leakage preserves efficiency in high-impedance bias networks |
| TJ max | +150 °C - Enables use in under-hood automotive or enclosed industrial power supplies |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case with matte tin-plated leads; polarity indicated by cathode band for unidirectional variants - P4SMA160C is bidirectional and marked with "RLJ" code; weight ≈ 0.060 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | 600 W rating, SMB package (larger footprint), 243 V clamping at 2.5 A | Better energy handling but requires PCB area increase; higher VC may stress 200 V-rated components | Select when higher single-pulse robustness is required and layout allows SMB footprint |
| 1.5KE160CA | 1500 W rating, DO-201 package (through-hole), 259 V clamping at 5.8 A | Not SMT-compatible; suited for prototyping or low-volume board-level repair, not automated production | Choose only for manual assembly or legacy through-hole designs needing higher surge margin |
Compared with SMBJ160CA and 1.5KE160CA, the P4SMA160C offers optimal balance of 400 W surge capacity, compact DO-214AC footprint, and 230 V clamping - making it preferred for space-constrained automotive and industrial SMT power rails where precise voltage limiting is critical.

FAQ
What does the 'C' suffix indicate in P4SMA160C?
The 'C' suffix in P4SMA160C denotes bidirectional configuration - meaning the device functions identically in both polarities, with symmetrical breakdown and clamping characteristics. Unlike unidirectional variants (e.g., P4SMA160A), P4SMA160C has no cathode marking and is used where AC-coupled or reversible voltage rails require protection without polarity constraints. This matches the electrical specifications shown for P4SMA160 in the datasheet table under "Devices for Bipolar Applications".
What is the maximum clamping voltage of P4SMA160C under standard test conditions?
The maximum clamping voltage of P4SMA160C is 230 V when subjected to a 10/1000 μs surge waveform at its rated peak pulse current of 1.8 A. This value is measured per ANSI/IEEE C62.35 and confirmed in the Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet (Version S2102). It defines the upper voltage limit imposed on protected circuitry during transient events.
Is P4SMA160C compliant with automotive transient immunity standards?
Yes, P4SMA160C meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, as explicitly stated in the FEATURES section of the datasheet. Its 400 W peak pulse power rating, fast <1.0 ps response, and specified clamping behavior ensure robust protection against load dump, relay switch-off, and alternator ripple transients common in 12 V and 24 V automotive systems.
What is the moisture sensitivity level (MSL) of P4SMA160C and how does it affect assembly?
P4SMA160C has a moisture sensitivity level of MSL 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions (<30 °C / 60% RH) without baking prior to reflow soldering. This eliminates pre-bake steps in SMT assembly, reduces process complexity, and avoids thermal stress on the device - critical for high-throughput automotive electronics manufacturing.
How does the temperature coefficient of VBR impact P4SMA160C performance in wide-temperature environments?
The temperature coefficient of VBR for P4SMA160C is 0.108 %/°C, meaning its breakdown voltage increases by approximately 0.108% per degree Celsius rise in junction temperature. Over the full –55 °C to +150 °C operating range, this results in a total VBR shift of ~22 V - well within the specified 144–176 V window. Designers must account for this drift when setting margin between VWM and minimum VBR in thermally demanding applications like engine bay electronics.
