Product details
Overview
P4SMA160CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power (10/1000μs), with a working stand-off voltage of 130V, breakdown voltage range 144–176V at 1mA, and clamping voltage of 230V at 1.8A. It protects DC/DC converters and automotive power modules against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA160CA datasheet, P4SMA160CA pinout, P4SMA160CA application, or P4SMA160CA equivalent, key selection criteria include bidirectional clamping capability, 150°C junction temperature rating, sub-1ps response time, low leakage (<1μA at VWM), and compliance with automotive surge immunity standards.
Technical Context
The P4SMA160CA employs a glass-passivated silicon junction optimized for fast transient suppression in bidirectional signal and power lines. Its electrical behavior follows ANSI/IEEE C62.35 definitions, with clamping validated under standardized 10/1000μs waveform testing.
Designed for surface-mount automation, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The DO-214AC package supports reflow profiles per J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA (Bourns) | Same 160V VWM, but 600W PPPM and DO-214AA (SMB) package (larger footprint) | Higher power handling suits higher-energy industrial transients; requires PCB layout change | Select SMBJ160CA only if system-level testing confirms >400W surge exposure and board space allows SMB footprint |
| 1.5SMC160CA (ON Semiconductor) | Same VWM/VC, but 1500W PPPM and DO-214AB (SMC) package (3.5× larger than SMA) | Designed for heavy-duty industrial equipment; incompatible with SMA land pattern | Choose 1.5SMC160CA only when legacy SMC footprint exists or extreme surge robustness (>1kW) is mandated |
Compared with SMBJ160CA and 1.5SMC160CA, the P4SMA160CA delivers optimal balance of 400W surge capability, compact DO-214AC footprint, and automotive-grade reliability-making it ideal for space-constrained, cost-sensitive designs where 400W compliance suffices.

FAQ
What does the 'CA' suffix indicate in P4SMA160CA?
The 'CA' suffix in P4SMA160CA denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., P4SMA160A), the P4SMA160CA has identical clamping characteristics regardless of voltage polarity-critical for AC-coupled or floating-bus applications. This is confirmed in the datasheet's "Devices for Bipolar Applications" section.
What is the maximum clamping voltage of P4SMA160CA under standard test conditions?
The maximum clamping voltage of P4SMA160CA is 230 V, measured at a peak impulse current (IPPM) of 1.8 A using the standardized 10/1000 μs double-exponential waveform. This value is specified in the Electrical Specifications table on page 3 of the official Taiwan Semiconductor datasheet (Version S2102) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is P4SMA160CA compliant with automotive transient standards?
Yes, P4SMA160CA meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b-covering common automotive electrical disturbances including load dump, switch-off spikes, and coupled noise. This compliance is explicitly stated in the FEATURES section of the datasheet and validated through standardized surge testing per the specification's waveform definitions.
What is the moisture sensitivity level (MSL) rating for P4SMA160CA?
P4SMA160CA has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it has unlimited floor life and may be mounted directly after removal from packaging without baking or dry storage. This rating is confirmed in the FEATURES list and simplifies SMT assembly for high-volume manufacturing environments.
How does the P4SMA160CA differ from the P4SMA160A variant?
The P4SMA160CA is bidirectional, while P4SMA160A is unidirectional. Their breakdown voltages differ: P4SMA160A has VBR = 152–168 V (min/max), whereas P4SMA160CA has VBR = 144–176 V. Both share identical VWM (130 V), PPPM (400 W), and DO-214AC packaging-but only P4SMA160CA clamps equally in both polarities, making it suitable for AC or floating-rail protection.
