DC current gain is specified at a minimum of 40 at 30 mA collector current and 10 Vce — a moderate beta that keeps base drive requirements manageable for a 500 mA load.
The TO-92AP variant uses formed leads and ships in Tape & Box (TB) — a bulk-style packaging suited for hand-assembly or low-volume production.
The maximum junction temperature is rated at 150°C — no separate ambient operating range is listed.
This part is obsolete, so buyers urgently need a drop-in substitute to avoid redesign.
Design engineers must verify pin compatibility before substituting or using the part.
Obsolete parts have limited stock; availability directly impacts procurement decisions.
Pricing varies across distributors and is critical for BOM costing.
Buyers need to know which distributors still carry this obsolete part.
Technical validation requires exact electrical and thermal parameters.
