Product details
Overview
P4SMA200AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power, 200V maximum standoff voltage (VWM = 171 V), and clamping voltage of 274 V at 1.51 A (10/1000 μs waveform), designed for overvoltage protection in automotive DC/DC converters and industrial power supplies.
For engineers reviewing the P4SMA200AH datasheet, P4SMA200AH pinout, P4SMA200AH application, or P4SMA200AH equivalent, key selection criteria include its AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, <1.0 ps response time, <1 µA leakage above 10 V, and glass-passivated junction for stable clamping under repetitive surge stress.
Technical Context
The P4SMA200AH operates as a unidirectional avalanche diode with a single-die configuration, leveraging a glass-passivated PN junction to achieve fast transient response (<1.0 ps) and low leakage (<1 µA at VWM). Its breakdown voltage range is 190–210 V at 1.0 mA test current, ensuring precise voltage thresholding for high-voltage rail protection.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing and ISO 7637-2 transient immunity standards (Pulse 1, 2a, 2b, 3a, 3b), with operating junction temperature from –55°C to +150°C and moisture sensitivity level 1 per J-STD-020 - enabling robust performance in under-hood and industrial environments without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR min/max | 190 / 210 V @ 1.0 mA - Confirmed avalanche onset range ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 274 V @ 1.51 A (10/1000 μs) - Clamping voltage limits downstream circuit stress during standardized surge events. |
| PPPM | 400 W - Peak pulse power rating per 10/1000 μs waveform; determines survivability against defined transients. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage preserves efficiency and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature enables operation in high-ambient automotive and industrial enclosures. |
| Response time | <1.0 ps - Sub-picosecond avalanche response ensures suppression before sensitive ICs experience overstress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same DO-214AA package; 200 V VWM, 224 V VC @ 1.79 A, 600 W PPPM - higher power rating but larger footprint. | Preferred where board space allows larger SMB package and higher surge margin is required (e.g., outdoor telecom power). | Select SMBJ200A only if 600 W rating is needed and DO-214AA layout is available; P4SMA200AH offers tighter VBR tolerance and smaller SMA footprint. |
| 1.5SMC200A | DO-214AB (SMC) package; 200 V VWM, 274 V VC @ 1.5 A, 1500 W PPPM - significantly higher power, larger body, higher thermal mass. | Suitable for mains-connected industrial equipment requiring IEC 61000-4-5 Level 4 immunity (4 kV/2 Ω). | Choose 1.5SMC200A for high-energy surge environments; P4SMA200AH is optimized for space-constrained automotive and embedded DC/DC designs. |
Compared with SMBJ200A and 1.5SMC200A, the P4SMA200AH delivers identical clamping voltage (274 V) at lower peak current (1.51 A), in the smallest DO-214AC footprint - making it optimal for dense PCB layouts where 400 W surge capability suffices and thermal mass constraints limit larger packages.

FAQ
What is the breakdown voltage range for P4SMA200AH?
The P4SMA200AH has a specified breakdown voltage (VBR) range of 190 V to 210 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight 10% tolerance ensures consistent clamping behavior across production lots and temperature extremes, directly supporting design margining for 200 V nominal systems.
Is P4SMA200AH suitable for bidirectional transient protection?
No - P4SMA200AH is a unidirectional TVS diode. For bidirectional applications, Taiwan Semiconductor specifies parts with "CH" or "CAH" suffixes (e.g., P4SMA200CH). Using P4SMA200AH in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche capability.
What is the maximum clamping voltage of P4SMA200AH under standard surge conditions?
The P4SMA200AH clamps to a maximum of 274 V when subjected to a 10/1000 μs waveform peak impulse current of 1.51 A. This value is guaranteed per datasheet test conditions and forms the basis for downstream component voltage rating selection in protected circuits.
Does P4SMA200AH require special handling during reflow soldering?
No - P4SMA200AH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be reflowed using standard lead-free profiles (peak 260°C) without pre-baking. Its matte tin-plated leads comply with J-STD-002 for reliable solder wetting.
How does P4SMA200AH meet automotive electromagnetic compatibility requirements?
P4SMA200AH meets ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a (battery disconnect), Pulse 2b (load dump), and Pulses 3a/3b (capacitive coupling and supply line noise), enabling system-level compliance in automotive ECUs and power modules without additional external filtering.
