Automotive-grade PNP — 5.5 A saturation at 175 mV
The ZXTP2008ZQTA is a 30 V, 5.5 A PNP bipolar transistor in a SOT-89-3 (TO-243AA) package, qualified to AEC-Q101 for automotive applications. Its low Vce(sat) of 175 mV at 5.5 A (Ib=500 mA) keeps conduction losses manageable in high-current switching and linear regulation stages.
Active lifecycle — AEC-Q101 compliance
The AEC-Q101 qualification means the transistor has passed the automotive-grade stress tests (high-temperature reverse bias, temperature cycling, ESD) required for Tier-1 PPAP submissions.
Sourcing and cross-reference note
The closest peer in the same family is the ZXTP2013ZTA, which offers a higher VCEO of 100 V but a lower continuous collector current of 3.5 A and a higher Vce(sat) of 300 mV at 4 A. The ZXTP2008ZQTA is the better fit for a 30 V rail requiring the full 5.5 A with lower saturation voltage. Both parts share the SOT-89-3 footprint and pinout, so a board laid out for the ZXTP2013ZTA can accept the ZXTP2008ZQTA without a PCB change — only the current and voltage ratings differ.
