Product details

Overview

P4SMA200A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power lines and signal paths. It features a 171 V working stand-off voltage (V_WM), 190–210 V breakdown voltage (V_BR), 274 V maximum clamping voltage (V_C) at 1.51 A peak pulse current, 400 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +150 °C junction temperature range - deployed in on-board DC/DC converters and industrial SMPS inputs.

For engineers reviewing the P4SMA200A datasheet, P4SMA200A pinout, P4SMA200A application, or P4SMA200A equivalent, this page delivers verified electrical specs, DO-214AC package details, clamping performance under ISO 7637-2 transients, thermal derating behavior, and direct alternatives with documented V_BR, V_C, and I_PPM differences.

Technical Context

The P4SMA200A employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps) and low leakage (<1 µA at 171 V). Its unidirectional configuration provides asymmetric clamping: forward conduction limited by 3.5 V @ 25 A, reverse protection defined by V_BR = 190–210 V @ 1.0 mA and V_C = 274 V @ 1.51 A (10/1000 µs waveform).

Thermal design is constrained by a 150 °C maximum junction temperature and derated peak power above 25 °C ambient per Fig.2. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow without preconditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	171 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below breakdown.
V_BR @ I_T	190–210 V @ 1.0 mA - Validated breakdown threshold defining turn-on precision for surge detection.
V_C @ I_PPM	274 V @ 1.51 A (10/1000 µs) - Clamped voltage during worst-case transient; determines protected circuit's maximum stress level.
P_PPM	400 W - Peak pulse power handling capability; defines energy absorption limit for standardized surges.
I_R @ V_WM	<1 µA - Reverse leakage at stand-off voltage; ensures minimal standby power loss and signal integrity.
T_J Range	–55 °C to +150 °C - Operational junction temperature window; supports under-hood and industrial ambient conditions.
Package	DO-214AC (SMA) - Standardized surface-mount outline with matte tin-plated leads; compatible with automated placement and J-STD-002 soldering.

Pinout & Package

DO-214AC (SMA) package: molded plastic case with cathode band marking; polarity-sensitive unidirectional operation; 0.060 g mass; UL 94V-0 rated compound; leads meet JESD201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry / Reverse surge return path	Connected to protected line's lower-potential side (e.g., GND or return rail); conducts during positive transients when cathode is at higher potential.
Cathode	Reverse surge clamp node / Forward current exit	Connected to protected line's higher-potential side (e.g., V_IN); avalanches into conduction when reverse voltage exceeds V_BR, shunting surge current to anode.

Key Features

Feature	Design Value
Glass-passivated junction	Enables stable V_BR tolerance (±5% for 'A' grade) and long-term reliability under repeated surge stress.
Fast response time <1.0 ps	Clamps ESD and lightning-induced transients before downstream ICs experience damaging overvoltage.
ISO 7637-2 compliance (Pulse 1/2a/2b/3a/3b)	Validated for automotive load-dump and inductive-switching immunity without external filtering.
Moisture Sensitivity Level 1	Zero floor-life limitation; can be mounted directly from reel without baking or dry-pack handling.
RoHS & halogen-free (IEC 61249-2-21)	Meets global environmental regulations for industrial and consumer end-equipment manufacturing.

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 (Bourns)	V_WM = 170 V, V_C = 328 V @ 1.22 A, same DO-214AA package but 2.5 mm wider body	Higher clamping voltage reduces protected circuit margin; requires PCB pad revision due to larger outline	Select when legacy SMB layout exists and 328 V clamping is acceptable for downstream 350 V-rated components.
1.5KE200A (ON Semiconductor)	V_WM = 171 V, V_C = 274 V @ 1.5 A, but axial DO-15 package (not SMT)	Requires through-hole assembly and manual rework; incompatible with automated SMT lines	Choose only for prototyping or low-volume repair where DO-15 footprint is already established.

Compared with SMBJ200A and 1.5KE200A, the P4SMA200A offers identical clamping performance (274 V) in a smaller DO-214AC footprint, enabling higher board density and full compatibility with high-speed pick-and-place systems - critical for volume automotive and industrial power designs.

FAQ

What is the maximum clamping voltage of the P4SMA200A under standard test conditions?

The P4SMA200A has a maximum clamping voltage (V_C) of 274 V when subjected to a 10/1000 µs waveform with a peak pulse current (I_PPM) of 1.51 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The P4SMA200A maintains this clamping performance across its specified operating temperature range and is validated for ISO 7637-2 compliance.

Is the P4SMA200A suitable for bidirectional transient suppression?

No, the P4SMA200A is a unidirectional TVS diode and is not rated for bidirectional operation. For bidirectional applications, Taiwan Semiconductor specifies parts with "C" or "CA" suffixes (e.g., P4SMA200CA). Using the P4SMA200A in reverse-biased configurations beyond its specified V_WM of 171 V may result in premature failure or undefined clamping behavior. Always verify polarity alignment in-circuit for the P4SMA200A.

What is the leakage current specification for the P4SMA200A at its working stand-off voltage?

The P4SMA200A exhibits a maximum reverse leakage current (I_R) of 1 µA when biased at its working stand-off voltage (V_WM) of 171 V and tested at 25 °C. This ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes such as feedback dividers or microcontroller reset inputs. The P4SMA200A maintains sub-µA leakage across its full operating temperature range.

Does the P4SMA200A require moisture sensitivity handling prior to reflow soldering?

No, the P4SMA200A is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry packing, baking, or special handling before surface-mount reflow. This simplifies manufacturing logistics and eliminates yield loss from moisture-related popcorning. The P4SMA200A's DO-214AC package is qualified for standard lead-free reflow profiles without preconditioning.

How does the P4SMA200A's thermal derating behave above 25 °C ambient temperature?

The P4SMA200A's peak pulse power (400 W) is linearly derated above 25 °C ambient per Figure 2 in the official datasheet, reaching zero power capability at 150 °C case temperature. At 85 °C ambient, its usable P_PPM drops to approximately 260 W. This derating must be applied when sizing the device for sustained surge duty cycles in enclosed or high-temperature environments. The P4SMA200A's 150 °C T_J_MAX rating supports operation in thermally demanding locations when board-level thermal management is implemented.
