TLP151A(TPR,E)

Isolators - Gate Drivers Overview

The TLP151A(TPR,E) is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs infrared LED with a high-voltage output photo-IC, housed in a compact SOIC-6 (5-lead) surface-mount package. The device supports an operating voltage range of 10 V to 30 V and provides robust electrical isolation of 3750 Vrms. Key electrical parameters include a maximum propagation delay of 500 ns, with rise and fall times of 50 ns each. It features a forward voltage of 1.55 V, a reverse voltage rating of 5 V, and a maximum forward current of 10 mA. The component operates within a temperature range of -40°C to +110°C and has a power dissipation rating of 80 mW.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (TPR,E) to confirm the reel packaging format, as the base model TLP151A(E) utilizes tube packaging. Ensure compatibility with RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer part number with official Toshiba documentation to distinguish between different tape-and-reel configurations within the same functional family.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel gate driver with moderate speed (500 ns delay) and high isolation voltage (3750 Vrms) is required. The SOIC-6 package is suitable for space-constrained PCB designs. Consider the 10 mA input current requirement for drive circuit design. This device is appropriate for applications where cost-effective isolation is prioritized over ultra-high-speed switching performance.

Isolators - Gate Drivers Part Context

The TLP151A belongs to Toshiba's TLP151 series of photocouplers designed specifically for gate driver applications. These devices are engineered to replace traditional transformer-based isolation in power electronics. The series offers a balance of isolation strength and switching speed, making it a standard choice for medium-power inverter and converter topologies in industrial and consumer electronics.
