Overview
The BA159 is a fast recovery rectifier diode manufactured by Diotec Semiconductor, designed for standard commercial and industrial applications. It features an average forward current (IFAV) of 1 A and a peak forward surge current (IFSM) of 40 A at 60 Hz. The device operates within a junction temperature range of -50°C to +150°C and a storage temperature range of -50°C to +175°C. Key electrical characteristics include a maximum forward voltage of 1.3 V at 1 A, a reverse leakage current of less than 5 µA at 25°C, and a typical reverse recovery time (trr) of under 300 ns.
Feature Summary
- Fast recovery performance with a reverse recovery time of less than 300 ns
- High thermal stability supporting junction temperatures up to 150°C
- Robust surge handling capability with a peak forward surge current of 40 A
Applications
- Standard commercial and industrial rectification circuits
- Power supply output rectification
- General-purpose freewheeling diodes in low-frequency switching applications
Procurement Notes
Verify the specific part number against official Diotec Semiconductor documentation to confirm package type and marking codes. Ensure that the intended application falls within standard commercial or industrial reliability grades, as automotive-grade variants require separate qualification verification. Confirm compliance requirements such as RoHS status directly from the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a 1 A continuous current rating and fast recovery characteristics are required for general-purpose rectification. Consider the thermal resistance values and derating curves if operating near the upper limits of the ambient temperature range. Ensure the circuit design accommodates the specified peak surge current ratings during transient events to maintain long-term reliability.
Part Context
The BA159 belongs to the BA157 through BA159 series of fast recovery rectifier diodes produced by Diotec Semiconductor. This family shares common physical dimensions and basic electrical structures but varies primarily in their repetitive peak reverse voltage ratings. The series is engineered for cost-effective solutions in standard power conversion tasks where moderate speed and high current capacity are prioritized over ultra-fast switching speeds.
Replacement Considerations
Cross-reference with other BA15x series parts only if reverse voltage requirements differ. Verify pinout compatibility and thermal dissipation characteristics when substituting with similar 1 A fast recovery diodes from other manufacturers.
