Product details
Overview
P4SMA180C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power, 146V working stand-off voltage, and 258V maximum clamping voltage at 1.6A 10/1000μs surge current-designed to protect DC/DC converters and automotive power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA180C datasheet, P4SMA180C pinout, P4SMA180C application, or P4SMA180C equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, JEDEC-compliant DO-214AC mechanical data, and direct alternatives with documented VBR, VC, and IPPM differences for robust overvoltage protection design.
Technical Context
The P4SMA180C implements a glass-passivated silicon junction optimized for fast transient response (<1.0 ps), low leakage (<1 μA at 146V), and stable bidirectional clamping across -55°C to +150°C operating range. Its breakdown voltage is specified at 162–198 V (min/max) with 1.0 mA test current, and temperature coefficient of VBR is 0.108 %/°C.
It meets ISO 7637-2 for automotive load-dump and switching transient immunity, features matte tin-plated leads compliant with J-STD-002 solderability, and carries UL 94V-0 flammability-rated molding compound-enabling reliable use in harsh industrial and automotive environments without derating below 125°C ambient.
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 |
|---|---|---|---|
| SMBJ180CA | Same VWM (146V), higher IPPM (2.0A), larger SMB package (DO-214AA) | Higher surge current capacity but requires 30% more PCB area; not drop-in compatible with SMA footprint. | Select when surge repetition rate exceeds 1 Hz and board space allows larger package. |
| 1.5KE180CA | Same VBR range, through-hole DO-15 package, 1500W rating but slower response (>1 ns) | Not suitable for automated SMT assembly; used where manual repair or high-energy single-event protection is prioritized over speed. | Choose only for legacy through-hole designs or where 1.5kW single-pulse capability outweighs SMT compatibility and sub-nanosecond response. |
Compared with SMBJ180CA and 1.5KE180CA, the P4SMA180C offers optimal balance of SMT manufacturability, 400W/1.6A surge handling, and <1.0 ps response in the industry-standard DO-214AC footprint-making it preferred for high-volume automotive and industrial DC power interfaces requiring repeatable, automated placement.

FAQ
What is the breakdown voltage range for P4SMA180C?
The P4SMA180C has a minimum breakdown voltage (VBR) of 162 V and a maximum of 198 V, measured at 1.0 mA test current per ANSI/IEEE C62.35. This range ensures consistent clamping behavior across production lots and temperature extremes, supporting robust design margins in 24V and 48V systems where the P4SMA180C is commonly deployed.
Is P4SMA180C unidirectional or bidirectional?
The P4SMA180C is a bidirectional TVS diode, indicated by the "C" suffix per Taiwan Semiconductor's ordering convention. It provides symmetrical clamping in both polarities-no cathode marking is present-and is electrically identical in forward and reverse bias, making it ideal for AC-coupled lines or differential bus protection where polarity reversal may occur.
What is the maximum clamping voltage of P4SMA180C under surge conditions?
The P4SMA180C clamps to a maximum of 258 V when subjected to a 10/1000 μs waveform with a peak impulse current (IPPM) of 1.6 A. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during standardized surge events such as ISO 7637-2 Pulse 1.
Does P4SMA180C meet automotive transient immunity standards?
Yes, the P4SMA180C is explicitly rated to meet ISO 7637-2 for automotive applications, covering Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive discharge). Its 400W peak power rating, 150°C junction rating, and glass-passivated junction ensure compliance in engine control, body electronics, and ADAS power domains where the P4SMA180C is routinely applied.
What package type does P4SMA180C use and is it RoHS compliant?
The P4SMA180C uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, with moisture sensitivity level (MSL) 1-enabling unlimited floor life and reflow compatibility without baking, critical for high-yield SMT production of boards using the P4SMA180C.
