Overview
The BY134 is a silicon rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose rectification applications. It features a standard recovery characteristic with a maximum repetitive peak reverse voltage of 600V and an average forward current rating of 1A. The device is housed in the DO-204AC (DO-41) axial leaded package, suitable for through-hole mounting. Key electrical parameters include a maximum forward voltage of 1.3V at rated current, a non-repetitive peak forward surge current capability of 50A, and a low reverse leakage current of 5µA. It operates within a junction temperature range of -50°C to +175°C.
Feature Summary
- High thermal stability with a maximum operating junction temperature of 175°C
- Robust surge current handling capability for transient protection
- Low forward voltage drop for improved efficiency
- Compliant with RoHS and REACH directives
Applications
- General-purpose rectification in power supplies
- Inverter circuits
- Free-wheeling diodes in motor drives
- DC-DC converter output stages
Procurement Notes
Verify the specific part marking and datasheet revision when sourcing, as manufacturers may update specifications or packaging formats over time. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Check for compliance certifications such as RoHS if required by your manufacturing standards. Ensure the DO-41 package dimensions match your PCB layout requirements before finalizing procurement.
Selection Notes
Select the BY134 when a 600V blocking voltage and 1A continuous current are required in a through-hole configuration. Consider this component for applications needing high surge tolerance and wide temperature operation up to 175°C. Compare against similar series like BY133 or BY135 if voltage ratings need adjustment while maintaining the same current and package constraints.
Part Context
The BY134 belongs to Diotec's BYX series of standard recovery rectifiers. This series is characterized by high reliability and robust construction for industrial and consumer electronics. The DO-41 package is a widely adopted standard for axial leaded diodes, facilitating easy integration into legacy and modern printed circuit board designs requiring through-hole technology.
Replacement Considerations
Publicly confirmed substitute part numbers include BY133 and BY135 from the same manufacturer series. Cross-brand equivalents should be verified against the 600V/1A/DO-41 specification matrix to ensure pin compatibility and electrical performance parity.
