Product details
Overview
P4SMA200H from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode with a 162V working stand-off voltage, 180–220V breakdown range at 1mA, and 287V maximum clamping voltage under 10/1000μs surge. It features glass passivated junction, AEC-Q101 qualification, and is used for overvoltage protection in automotive DC/DC converters and industrial power supplies.
For engineers reviewing the P4SMA200H datasheet, P4SMA200H pinout, P4SMA200H application, or P4SMA200H equivalent, key selection criteria include clamping performance at rated peak pulse current (1.4A), low leakage (<1μA at 162V), ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and DO-214AC (SMA) package suitability for automated SMT assembly.
Technical Context
The P4SMA200H operates as a unidirectional avalanche diode, leveraging a glass-passivated silicon junction to achieve fast response (<1.0ps) and stable breakdown characteristics across –55°C to +150°C junction temperature. Its clamping behavior is defined by a 10/1000μs double-exponential surge waveform per IEC 61000-4-5 and ANSI/IEEE C62.35.
It is rated for 400W peak pulse power at 25°C with linear derating above that ambient, supports 40A non-repetitive forward surge (8.3ms half-sine), and maintains <3.5V forward voltage at 25A - enabling robust protection in high-energy transients without forward conduction interference.

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 | 600W rating, DO-214AA (SMB) package, bidirectional variant standard; VC = 324V @ 1.9A | Higher power handling but larger footprint; requires layout change; better suited for 48V systems with higher surge budgets. | Select SMBJ200A only if system-level surge energy exceeds 400W or DO-214AC footprint is insufficient. |
| 1.5SMC200A | 1500W rating, DO-214AB (SMC) package, VC = 324V @ 4.7A; higher thermal mass | Designed for board-level primary protection; not optimized for space-constrained automotive modules. | Choose 1.5SMC200A for front-end AC/DC input stages where PCB area allows and peak current exceeds 1.4A. |
Compared with SMBJ200A and 1.5SMC200A, the P4SMA200H offers optimal balance of compact DO-214AC footprint, AEC-Q101 qualification, and precise 287V clamping - making it preferred for space-limited, automotive-grade secondary-side protection where 400W surge capacity suffices.

FAQ
What is the clamping voltage of the P4SMA200H under standard surge conditions?
The P4SMA200H has a maximum clamping voltage (VC) of 287 V when subjected to a 10/1000μs surge waveform with peak current (IPPM) of 1.4 A. This value is guaranteed per the datasheet and defines the upper voltage limit imposed on protected circuits during transient events. The P4SMA200H maintains this clamping performance across its specified operating temperature range and is validated per ANSI/IEEE C62.35 test methodology.
Is the P4SMA200H suitable for automotive applications?
Yes, the P4SMA200H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements - confirming its suitability for 12V and 24V automotive electrical systems. Its DO-214AC package, glass passivated junction, and –55°C to +150°C operating range make the P4SMA200H appropriate for engine control units, body electronics, and ADAS power domains where reliability under thermal and electrical stress is critical.
What is the difference between P4SMA200H and P4SMA200AH?
The P4SMA200AH is the tighter-tolerance variant of the P4SMA200H, with a narrower breakdown voltage range (190–210 V vs. 180–220 V) and slightly higher clamping voltage (274 V vs. 287 V) at its rated 1.51 A surge current. Both share identical package, power rating (400 W), and AEC-Q101 qualification. The P4SMA200H offers broader VBR tolerance for cost-sensitive designs, while the P4SMA200AH provides improved consistency for precision-clamp applications.
Does the P4SMA200H have polarity marking, and how is it identified?
Yes, the P4SMA200H is unidirectional and features a cathode band marked on the DO-214AC (SMA) package body. Per the manufacturer's marking diagram, the cathode band indicates the terminal that connects to the protected line (high-side), while the anode connects to ground or return. This polarity must be observed during PCB layout to ensure proper reverse-bias operation and effective clamping during overvoltage events. The P4SMA200H's cathode band aligns with JEDEC-standard SMA orientation.
What is the maximum surge current the P4SMA200H can handle in a single event?
The P4SMA200H is rated for a maximum peak impulse current (IPPM) of 1.4 A under the standard 10/1000μs double-exponential waveform. This corresponds to its 400W peak pulse power rating at 25°C. While it can withstand higher short-duration currents (e.g., 40 A for 8.3ms half-sine per IFSM rating), the 1.4 A value reflects the industry-standard surge condition used for clamping voltage specification and system-level immunity validation. The P4SMA200H's performance at this level is fully characterized and guaranteed in the datasheet.
