Product details
Overview
P4SMA160H from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with a working stand-off voltage of 130 V, breakdown voltage range 144–176 V at 1 mA, clamping voltage of 230 V at 1.8 A (10/1000 µs), and AEC-Q101 qualification for automotive-grade surge protection in DC/DC converters and power supplies.
For engineers reviewing the P4SMA160H datasheet, P4SMA160H pinout, P4SMA160H application, or P4SMA160H equivalent, this page delivers verified electrical parameters, mechanical packaging details, real-world use cases in automotive and industrial power systems, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The P4SMA160H operates as a unidirectional avalanche diode optimized for fast transient suppression on DC power rails. Its glass-passivated junction enables stable breakdown behavior and low leakage (<1 µA at 130 V), while its 1.0 ps typical response time ensures effective clamping of ESD and load-dump pulses per ISO 7637-2 (Pulse 1/2a/2b/3a/3b).
Designed for surface-mount assembly and compliant with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, the device supports automated placement and reflow soldering without derating concerns up to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC rail margin for 12–48 V systems with transients. |
| VBR @ IT=1 mA | 144–176 V - Breakdown voltage range confirming reliable avalanche initiation under standardized test conditions. |
| VC @ IPPM=1.8 A | 230 V - Clamping voltage during 10/1000 µs surge; limits downstream component stress during 400 W peak pulse events. |
| IPPM | 1.8 A - Peak impulse current capability at rated clamping voltage; correlates directly to surge energy handling (400 W, 1 ms). |
| TJ max | 150 °C - Maximum junction temperature enabling operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Leakage IR @ VWM | <1 µA - Ultra-low reverse leakage preserves efficiency in always-on power monitoring circuits and battery-backed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | DO-214AA (SMB) package; 1.0 A IPPM at 230 V; same VWM/VC but lower peak power (600 W vs. 400 W rating differs due to waveform definition) | Higher thermal mass but larger footprint; less suitable for ultra-dense automotive PCBs requiring SMA size | Select SMBJ160A only if board space allows DO-214AA and higher IPPM margin is required beyond 1.8 A. |
| 1.5SMC160A | DO-214AB (SMC) package; 2.5 A IPPM at 230 V; 1500 W peak power rating (10/1000 µs); higher capacitance (~100 pF vs. ~30 pF) | Better energy handling but unsuitable for high-frequency signal lines due to parasitic capacitance | Choose 1.5SMC160A for high-energy industrial mains interfaces where layout space permits SMC and speed is secondary. |
Compared with P4SMA160H, SMBJ160A offers identical clamping performance in a larger package with lower surge current capacity, while 1.5SMC160A provides superior energy absorption but introduces higher junction capacitance that may affect signal integrity in fast-switching applications.

FAQ
What is the maximum clamping voltage of P4SMA160H under standard surge conditions?
The P4SMA160H has a maximum clamping voltage (VC) of 230 V when subjected to a 10/1000 µs surge waveform at IPPM = 1.8 A. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream components in 130 V nominal systems. The P4SMA160H maintains this clamping performance across its full operating temperature range (−55 °C to +150 °C).
Is P4SMA160H suitable for bidirectional transient protection?
No, P4SMA160H is a unidirectional TVS diode intended for DC rail protection with defined anode–cathode polarity. For bidirectional applications, Taiwan Semiconductor specifies parts with "CH" or "CAH" suffixes (e.g., P4SMA160CH). Using P4SMA160H in reverse-biased AC configurations risks failure due to lack of symmetrical breakdown characteristics. Always verify polarity marking and circuit topology before deploying P4SMA160H.
Does P4SMA160H meet automotive qualification standards?
Yes, P4SMA160H is AEC-Q101 qualified and tested per the full stress test schedule including HTGB, HTRB, temperature cycling, and ESD. It also meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive electrical disturbance immunity. These qualifications make P4SMA160H appropriate for engine control units, body electronics, and ADAS power domains where reliability under harsh environmental conditions is mandatory.
What is the leakage current specification for P4SMA160H at its working voltage?
At its working stand-off voltage (VWM) of 130 V, the P4SMA160H exhibits a maximum reverse leakage current (IR) of 1 µA at 25 °C. This ultra-low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensing nodes. Leakage remains below 5 µA up to 150 °C, supporting stable operation in under-hood automotive environments.
What package type and mounting method does P4SMA160H use?
P4SMA160H uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability requirements. It is designed for reflow soldering on PCBs using standard lead-free profiles and supports automated pick-and-place assembly. The cathode band marking aligns with IPC-7351B land pattern recommendations, and the package meets UL 94V-0 flammability rating.
