Learnings & Edge Cases
- 1N400x voltage order: 1N4001=50V, 1N4002=100V, ..., 1N4007=1000V. The digit maps to voltage rating.
- 1N540x voltage order: 1N5400=50V, 1N5401=100V, ..., 1N5408=800V. Similar pattern but different mapping.
- MMBT vs 2N: MMBT is the SMD (SOT-23) equivalent of 2N through-hole transistors. Same electrical specs, different package.
- PN vs 2N: PN series (PN2222) is plastic-packaged version of 2N series. Generally interchangeable with 2N.
- 1N4148 vs 1N914: These are electrically equivalent signal diodes. Can be used interchangeably.
- SS current rating: First digit indicates current (SS14=1A, SS34=3A). Higher current can replace lower.
- S80xx/S90xx series: Common in Asian markets. S8050/S8550 are general purpose NPN/PNP pairs.
- BAV70/BAV99: Dual diode packages (SOT-23). BAV70 = common cathode, BAV99 = series pair.
