Product details
Overview
P4SMA200CAH from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It delivers 400W peak pulse power handling, a 171V working stand-off voltage (VWM), a 190–210V breakdown voltage (VBR) at 1mA test current, and clamps transients to ≤274V at 1.51A (10/1000μs waveform). It is used in on-board DC/DC converters to protect sensitive 24V/48V control circuitry against ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transients.
For engineers reviewing the P4SMA200CAH datasheet, P4SMA200CAH pinout, P4SMA200CAH application, or P4SMA200CAH equivalent, key selection criteria include its bidirectional configuration, DO-214AC (SMA) package compatibility with automated placement, AEC-Q101 qualification for automotive use, and verified clamping performance under standardized 10/1000μs surge conditions.
Technical Context
The P4SMA200CAH is a glass-passivated, single-die, bidirectional TVS diode optimized for fast transient suppression in harsh electrical environments. Its junction structure enables sub-1ps response time and low leakage (<1μA at VWM), while its thermal design supports continuous operation from –55°C to +150°C junction temperature.
It meets ISO 7637-2 for automotive transient immunity and complies with JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1. The device operates symmetrically in both polarities, eliminating polarity marking dependency in layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for 24V/48V systems. |
| VBR min/max | 190 / 210 V @ 1 mA - Tight 10% breakdown tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 274 V @ 1.51 A (10/1000μs) - Clamping voltage during standardized surge; determines maximum stress on downstream ICs. |
| PPPM | 400 W - Peak pulse power rating per JEDEC/IEC standards; validates robustness against repetitive surges. |
| IR @ VWM | <1 μA - Ultra-low reverse leakage preserves efficiency in always-on monitoring circuits. |
| TJ max | +150 °C - Enables deployment in engine bay or under-hood modules without derating. |
| Configuration | Bidirectional - Supports AC-coupled or floating-rail protection without polarity constraints. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no polarity orientation required during placement-reduces assembly error risk. |
Key Features

|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives. |
| Fast response time <1 ps | Clamps ESD and fast-edge transients before sensitive logic or analog inputs are disturbed. |
| Meets ISO 7637-2 Pulse 1/2a/2b/3a/3b | Guarantees system-level compliance for 12V/24V vehicle networks without additional filtering. |
| Moisture Sensitivity Level 1 | Enables standard SMT reflow without baking or special handling-lowers manufacturing cost. |
Applications
| Switching Mode Power Supply (SMPS) | On-board DC/DC Converter |
|---|---|
Use Scenario: Protection of primary-side MOSFET gate drivers and secondary-side feedback optocouplers against switching-induced voltage spikes. IC Role / Device Role: Bidirectional clamping element placed across input/output rails or across transformer windings. Use Value: Prevents cumulative gate oxide damage and feedback loop disruption by limiting transient excursions to ≤274V. | Use Scenario: Safeguarding isolated 3.3V/5V microcontroller supply rails in automotive ADAS domain controllers. IC Role / Device Role: Secondary-side rail protector between DC/DC output and load, absorbing coupled transients from CAN/LIN bus noise. Use Value: Maintains MCU uptime during cranking events by clamping ISO 7637-2 Pulse 2b (load dump) to non-disruptive levels. |
| Lighting Application | Adapters |
Use Scenario: Surge protection for LED driver ICs in exterior automotive lighting modules exposed to load dump and jump-start conditions. IC Role / Device Role: Input-stage TVS placed upstream of buck controller ICs to absorb energy before regulation stage. Use Value: Eliminates need for redundant overvoltage shutdown circuitry by providing hard-clamp behavior at 274V. | Use Scenario: Input-stage protection in universal AC/DC adapters for industrial IoT gateways subjected to mains-borne surges. IC Role / Device Role: Primary-side TVS across bridge rectifier output to clamp line-to-line and line-to-ground transients.

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 | 600W PPPM rating, SMB package (larger footprint), same VWM/VBR range and bidirectional configuration. | Higher power handling suits higher-energy surge environments (e.g., 48V commercial vehicle systems); requires PCB pad revision. | Select when system-level surge testing exceeds 400W or when thermal margin must be increased beyond DO-214AC limits. |
| 1.5KE200CA | Through-hole DO-15 package, 1500W PPPM, wider VBR tolerance (±10%), higher clamping voltage (292V). | Designed for legacy board designs with through-hole assembly; unsuitable for high-density SMT layouts. | Choose only for repair/replacement of existing DO-15-based designs where rework to SMT is not feasible. |
Compared with SMBJ200CA and 1.5KE200CA, the P4SMA200CAH offers optimal balance of space-constrained SMT compatibility, AEC-Q101 qualification, and validated ISO 7637-2 compliance-making it the preferred choice for new automotive electronics requiring DO-214AC footprint and automotive-grade reliability.

FAQ
What does the "CAH" suffix indicate in P4SMA200CAH?
The "CAH" suffix denotes a bidirectional configuration (C), AEC-Q101 qualification (A), and halogen-free construction (H). Unlike unidirectional variants (e.g., P4SMA200AH), the P4SMA200CAH provides symmetrical clamping in both voltage polarities-critical for protecting floating or AC-coupled signal paths without polarity concerns.
Is P4SMA200CAH suitable for ISO 7637-2 compliance testing?
Yes, the P4SMA200CAH is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its 400W peak pulse power rating, low clamping voltage (274V), and fast response time ensure reliable suppression of standardized automotive transients without requiring supplemental protection components.
What is the maximum clamping voltage of P4SMA200CAH under surge conditions?
The maximum clamping voltage VC of P4SMA200CAH is 274 V at a peak impulse current IPPM of 1.51 A using the 10/1000μs waveform. This value is measured per IEC 61000-4-5 and ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does P4SMA200CAH require polarity-aware PCB layout?
No-P4SMA200CAH is a bidirectional TVS diode with symmetrical terminal behavior. Its DO-214AC package has no cathode band or polarity marking, and both terminals perform identically under positive or negative transients. This eliminates orientation errors during automated placement and simplifies layout for differential or floating-rail protection schemes.
What is the junction temperature range for reliable operation of P4SMA200CAH?
The P4SMA200CAH supports continuous operation across a junction temperature range of –55°C to +150°C. This wide range enables deployment in under-hood automotive modules, industrial motor drives, and outdoor lighting systems where ambient temperatures exceed 105°C and thermal cycling is frequent.
