Engineering Selection Recommendations

BA158GP-AP (Primary Part)

• Active product status with 961 pieces in stock
• RoHS3 compliant and REACH unaffected
• Operating temperature range: -65°C ~ 150°C
• Forward voltage: 1.3 V @ 1 A
• Reverse recovery time: 150 ns

1N4937-E3/73 (Substitute Part)

• Active product status with 11,887 pieces in stock
• RoHS3 compliant and REACH unaffected
• Operating temperature range: -50°C ~ 150°C
• Forward voltage: 1.2 V @ 1 A (lower forward drop)
• Reverse recovery time: 200 ns

Both parts satisfy the core electrical requirements of 600 V reverse voltage and 1 A average rectified current with fast-recovery characteristics. The 1N4937-E3/73 offers superior stock availability and a lower forward voltage specification. Selection between these parts depends on circuit requirements for minimum junction temperature operation and forward voltage performance.
