BPW 34 SR-Z
Overview
The BPW 34 SR-Z is a high-speed silicon PIN photodiode designed for the 400nm to 1100nm spectral range, optimized specifically for 850nm peak sensitivity. It features a large 7mm2 active area in a low-profile surface mount DIL package, making it suitable for high-density PCB layouts. With a fast 20ns response time and low 2nA dark current, it is effective for both high-speed light barriers and precision light measurement.
Why Choose This Part
The component offers a wide 120-degree viewing angle and a high packing density DIL SMT package for compact designs. Its low junction capacitance and 32V reverse voltage rating allow for high-speed operation and low-noise performance. The 850nm optimization makes it an ideal match for standard IR emitters used in proximity and communication tasks.
Applications
Key Specifications
Getting Started
When designing with the BPW 34 SR-Z, implement a transimpedance amplifier (TIA) to convert the photocurrent to a usable voltage. Ensure the 7mm2 active area is clear of solder mask or obstructions, and use a reverse bias up to 32V to minimize response time for high-speed applications. Evaluation can be performed using standard SMT prototyping boards or custom PCB footprints following the 2-SMD Gull Wing dimensions.
