1. Introduction

The P6KE200A is a 1500W unidirectional TVS diode for 171V-200V DC rail protection. It clamps transients from lightning, inductive load switching, and ESD in industrial, telecom, and power supply applications.

The P6KE200A is a JEDEC-registered industry standard number, cross-compatible with Littelfuse, Vishay, ON Semi, Diodes Inc, STMicroelectronics, and Bourns. YINT Electronics manufactures it as a drop-in replacement in the DO-201 (DO-15) through-hole package.

Engineers searching for a P6KE200A replacement or P6KE200A alternative can specify the YINT P6KE200A with confidence. It offers < 1ns response time and 1500W peak pulse power (10/1000µs) for medium-voltage DC power rails.

2. Product Overview

The P6KE series covers breakdown voltages from 6.8V to 440V in the DO-15 package. Each device delivers 600W to 1500W peak pulse power, making the series suitable for low-voltage logic to high-voltage industrial power systems.

The P6KE200A protects 171V-200V DC power rails in industrial servo drives, telecom base stations, and solar inverters. Its 171V stand-off voltage lets it sit across the DC bus without conducting (1.0µA max leakage). It responds in under 1ns when a transient exceeds 190V minimum breakdown threshold.

YINT produces the full P6KE series from P6KE6.8A through P6KE440A. This enables customers to source all DO-15 TVS needs from one manufacturer.

3. Key Features

• Peak Pulse Power: 1500W — 10/1000µs waveform, for 171V-200V DC rail protection

A: Yes. The YINT P6KE200A has identical electrical specs and DO-201 package dimensions. It is a drop-in replacement for P6KE200A from all major manufacturers.

Q2: What is the difference between P6KE200A and P6KE200CA?
A: P6KE200A is unidirectional (for DC circuits). P6KE200CA is bidirectional (for AC circuits). Use P6KE200A for DC rail protection.

Q3: What is the peak pulse power rating?
A: 1500W for a 10/1000µs waveform at 25°C. Derate to 1200W at 100°C ambient.

Q4: Can P6KE200A be used for 220V AC protection?
A: No. For 220V AC mains, use P6KE350A (Vrwm 299V) or P6KE440A (Vrwm 376V). The P6KE200A is for DC rails up to 171V.

Q5: What package types are available?
A: DO-201 (DO-15) through-hole. For SMD alternatives, consider SMAJ200A (SMA), P4SMA200A (SMA), or SMCJ200A (SMC).

Q6: What is the response time?
A: Less than 1 nanosecond, providing instant protection against ESD and fast transients.
