Product details
Overview
P4SMA200CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It delivers 400W peak pulse power handling, a 171V working stand-off voltage (VWM), a 180–220V breakdown voltage (VBR) at 1mA test current, and clamps transients to ≤287V at 1.4A peak impulse current under 10/1000μs waveform - deployed in automotive power modules and industrial DC/DC converters.
For engineers reviewing the P4SMA200CA datasheet, P4SMA200CA pinout, P4SMA200CA application, or P4SMA200CA equivalent, key selection criteria include bidirectional clamping capability, DO-214AC (SMA) package compatibility with automated SMT assembly, compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and low leakage (<1μA at 171V) for low-power standby circuits.
Technical Context
The P4SMA200CA operates as a silicon avalanche diode configured in a symmetrical bipolar junction, enabling identical clamping behavior in both forward and reverse polarity surges. Its glass-passivated chip junction ensures stable VBR tolerance (±5% for A-grade variants) and long-term reliability under repeated transient stress.
It adheres to the 10/1000μs double-exponential surge waveform per R.E.A. and ANSI/IEEE C62.35, with thermal derating above 25°C per Fig.2 and peak power limited to 400W at TA = 25°C. Junction temperature range spans –55°C to +150°C, supporting under-hood and industrial ambient conditions.

Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; symmetrical bidirectional construction means no functional anode/cathode designation - both terminals serve identically as surge input/output nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Surge current entry point in either polarity; no fixed polarity assignment due to CA suffix design |
| Terminal 2 | Anode/Cathode (bidirectional) | Surge current return path; electrically identical to Terminal 1; marked with cathode band for mechanical orientation only |
Key Features
| Feature | Design Value |
|---|---|

| ISO 7637-2 compliance | Validated for automotive load-dump and inductive-switching transients (Pulse 1/2a/2b/3a/3b) |
| Fast response time | <1.0 ps - Limits voltage overshoot before clamping engages, protecting sensitive gate drivers and ADC inputs |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing and end-of-life processing |
Applications
| Automotive Power Distribution | Industrial DC/DC Converters |
|---|---|
Use Scenario: Protecting 24V CAN bus power rails and ECU supply inputs against load dump and jump-start surges. IC Role / Device Role / Timing Role: Standoff voltage clamp placed directly at connector entry point to shunt >100V transients before they reach LDOs or microcontrollers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA (Bourns) | Same DO-214AA package; 400W rating; VWM = 171V; VC = 287V - identical electrical specs but different thermal resistance (RθJA = 65°C/W vs. TSC's 70°C/W) | Compatible in space-constrained layouts where SMB footprint is preferred; slightly better thermal performance | Select SMBJ200CA if board real estate allows DO-214AA and higher thermal margin is required |
| 1.5KE200CA (ON Semiconductor) | Through-hole DO-15 package; same 400W rating and VWM/VC values; higher junction-to-ambient thermal resistance (RθJA = 100°C/W) | Not suitable for high-density SMT designs; requires wave-solder or hand-solder process | Choose 1.5KE200CA only for legacy through-hole assemblies or prototyping with breadboard compatibility |
Compared with SMBJ200CA and 1.5KE200CA, the P4SMA200CA offers optimal balance of SMT manufacturability, DO-214AC footprint standardization, and verified ISO 7637-2 compliance - making it preferred for new automotive and industrial power designs requiring surface-mount surge immunity.

FAQ
What does the 'CA' suffix indicate in P4SMA200CA?
The 'CA' suffix in P4SMA200CA denotes a bidirectional configuration - meaning the device provides symmetrical clamping in both polarities, with identical VBR, VC, and leakage characteristics regardless of voltage polarity applied. This eliminates the need for polarity-aware placement during SMT assembly and supports AC-coupled or floating DC applications. The P4SMA200CA achieves this via a back-to-back diode structure within a single DO-214AC package.
Does P4SMA200CA meet automotive surge immunity standards?
Yes, the P4SMA200CA meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a (sudden load removal), Pulse 2b (supply interruption), Pulse 3a (capacitive coupled transients), and Pulse 3b (inductive coupled transients). Its 400W peak pulse power rating and 287V clamping voltage at 1.4A ensure robust protection against common vehicle electrical disturbances - validated per the manufacturer's test reports and curve data in Figures 1–5 of the S2102 datasheet.
What is the maximum operating temperature for P4SMA200CA?
The P4SMA200CA has a specified operating junction temperature range of –55°C to +150°C. At ambient temperatures above 25°C, its peak pulse power must be linearly derated per Figure 2 in the datasheet - for example, at 85°C ambient, the usable PPPM drops to approximately 280W. This wide TJ range enables deployment in engine bay modules, industrial motor drives, and outdoor lighting systems without thermal shutdown concerns.
How does P4SMA200CA differ from the 'A' version (P4SMA200A)?
The P4SMA200CA is bidirectional, while P4SMA200A is unidirectional. Their VWM (171V), VBR (190–210V), and VC (274V) values are closely matched, but only the CA variant supports symmetrical clamping. The P4SMA200CA also features tighter VBR tolerance (±5%) versus ±10% for non-A grades, and its marking code (RTJ) explicitly identifies the bidirectional function - critical for correct schematic symbol and PCB layout interpretation.
Is P4SMA200CA halogen-free and RoHS compliant?
Yes, the P4SMA200CA is certified halogen-free per IEC 61249-2-21 and fully RoHS compliant per EU Directive 2011/65/EU. The molding compound contains no brominated flame retardants (BFRs), chlorinated flame retardants (CFRs), antimony trioxide, or phosphorus-based flame retardants exceeding threshold limits. Lead content is below 1000 ppm, and all six RoHS-restricted substances meet applicable exemptions and reporting requirements.
