1. Introduction

The P4SMA200A is a 400W unidirectional TVS diode for protecting compact electronics from voltage transients caused by switching and lightning events. It has a stand-off voltage of 171V and a breakdown voltage range of 190V to 210V. This diode is ideal for 200V DC rail protection in space-constrained PCB designs where through-hole parts cannot fit.

The P4SMA200A belongs to the P4SMA series in the SMA (DO-214AC) surface-mount package. It is compatible across major manufacturers including Littelfuse, Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, Bourns, MCC, and Taiwan Semiconductor. YINT Electronics manufactures this model as a fully compatible replacement with identical electrical specifications and package dimensions.

With a clamping voltage of 274V and peak pulse current of 1.46A, the P4SMA200A provides reliable protection for compact 200V DC circuits in industrial controls, LED drivers, and power supplies. Engineers seeking a P4SMA200A replacement or P4SMA200A alternative can use the YINT P4SMA200A as a direct drop-in equivalent for all major brands without any PCB redesign. YINT performs 100% surge testing on every device to guarantee compliance with published specifications for maximum designer confidence. The P4SMA200A offers medium-voltage protection in a small SMD package, ideal for designers needing to save PCB space without compromising on transient protection capability.

2. Product Overview

The P4SMA series is a popular surface-mount TVS diode family covering breakdown voltages from 5.0V to 440V in the SMA (DO-214AC) package. Each part delivers 400W of peak pulse power for automated SMT assembly processes. The series is designed for applications where PCB space is limited but medium-voltage protection is still required for system reliability.

The P4SMA200A is a 400W rated variant for protecting 200V DC rails in compact industrial and consumer devices. Its stand-off voltage of 171V allows normal operation on 171V to 200V DC lines without conducting under normal conditions. The device clamps transients to a maximum of 274V, matching the clamping voltage of larger 1500W parts in the same voltage class for consistent protection levels. This lets designers use the compact SMA package while keeping the same component voltage ratings as through-hole designs, simplifying cross-platform compatibility. Engineers can confidently replace through-hole TVS diodes with the P4SMA200A in board redesigns to save valuable PCB space.

YINT produces the full P4SMA series from P4SMA5.0A through P4SMA440A. This complete voltage range enables customers to source all P4SMA TVS diodes from one supplier, simplifying supply chain management and reducing qualification time. Advanced silicon avalanche technology and tight process controls ensure consistent breakdown voltage and surge current capability across every production lot for reliable long-term performance.
