Product details
Overview
P4SMA130CAH from Taiwan Semiconductor is a bidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with 117–143 V breakdown voltage (VBR), 105 V working stand-off voltage (VWM), and 179 V maximum clamping voltage (VC) at 2.3 A peak pulse current - designed for automotive-grade surge protection in DC/DC converters and power supply rails.
For engineers reviewing the P4SMA130CAH datasheet, P4SMA130CAH pinout, P4SMA130CAH application, or P4SMA130CAH equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, <1 µA leakage at VWM, and DO-214AC thermal derating up to 150°C junction temperature.
Technical Context
The P4SMA130CAH implements a glass-passivated silicon junction optimized for fast transient response (<1.0 ps) and low capacitance, enabling effective suppression of high-speed ESD and load-dump events. Its bidirectional configuration supports symmetrical clamping in AC-coupled or floating-rail systems without polarity constraints.
It operates across –55°C to +150°C junction temperature range, with thermal derating above 25°C ambient per Fig.2, and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - confirming suitability for reflow-soldered automotive and industrial PCB assemblies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | 600 W peak power, SMB package (larger footprint), same VBR/VC range | Better power handling but requires PCB layout change; not drop-in compatible | Select when higher surge margin is required and board space allows SMB outline |
| 1.5KE130CA | Through-hole DO-201 package, 1500 W rating, higher VC (219 V), slower thermal response | Not suitable for automated SMT assembly; used in legacy or high-reliability through-hole designs | Choose only for manual assembly or where mechanical robustness outweighs SMT compatibility |
Compared with SMBJ130CA and 1.5KE130CA, the P4SMA130CAH offers optimal balance of 400 W surge capability, DO-214AC SMT compatibility, AEC-Q101 qualification, and ISO 7637-2 compliance - making it the preferred choice for new automotive and industrial surface-mount designs requiring validated reliability and compact footprint.

FAQ
What does the "CAH" suffix indicate in P4SMA130CAH?
The "CAH" suffix denotes a bidirectional configuration with AEC-Q101 qualification and halogen-free construction. Unlike unidirectional "H" variants, P4SMA130CAH provides symmetrical clamping for both polarities - essential for protecting AC-coupled signals or floating power domains without polarity concerns. This designation is confirmed in TSC's ordering information and electrical specifications tables.
Is P4SMA130CAH suitable for ISO 7637-2 Pulse 1 (load dump) protection?
Yes, P4SMA130CAH is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms per its datasheet features section. With a 105 V VWM, 179 V VC, and 400 W peak power rating, it clamps 12 V system load-dump transients (up to ~120 V) within safe limits for downstream 150°C-rated controllers and regulators - verified in TSC's compliance statements and test condition notes.
What is the maximum clamping voltage of P4SMA130CAH under standard test conditions?
The maximum clamping voltage (VC) of P4SMA130CAH is 179 V at 2.3 A peak pulse current using the 10/1000 µs waveform, as specified in the Electrical Specifications table on page 3 of the TSC datasheet. This value represents the worst-case voltage imposed on protected circuitry during a standardized surge event - critical for validating margin against downstream IC absolute maximum ratings.
Does P4SMA130CAH require derating at elevated ambient temperatures?
Yes, P4SMA130CAH must be derated above 25°C ambient per Figure 2 (Pulse Derating Curve) in the TSC datasheet. At 85°C ambient, its 400 W peak pulse power rating reduces to approximately 240 W; at 125°C, it falls to ~120 W. This thermal derating ensures safe junction temperature (TJ ≤ 150°C) and is mandatory for automotive under-hood or enclosed industrial applications.
How does the DO-214AC (SMA) package of P4SMA130CAH compare to SMA-style alternatives from other manufacturers?
The DO-214AC (SMA) package of P4SMA130CAH conforms to JEDEC standard dimensions and solder pad layout recommendations, ensuring compatibility with standard SMT pick-and-place equipment and reflow profiles. Its 0.060 g mass, matte tin-plated leads (J-STD-002 compliant), and UL 94V-0 molding compound match industry benchmarks - enabling direct substitution in existing SMA-footprint designs without layout revision.
