Nexperia USA Inc. PMBTA56-QVL

Overview

PMBTA56-QVL from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −80 V V_CEO, −500 mA I_C, and 100 minimum h_FE at −10 mA collector current; it delivers automotive-grade switching and amplification in telephony and professional communication equipment.

For engineers reviewing the PMBTA56-QVL datasheet, PMBTA56-QVL pinout, PMBTA56-QVL application, or PMBTA56-QVL equivalent, this device supports AEC-Q101-qualified designs requiring reliable low-voltage PNP switching with verified thermal performance up to 150 °C junction temperature and validated SOT23 reflow footprint compatibility.

Technical Context

This PNP BJT operates with open-base collector-emitter breakdown voltage of −80 V and emitter-base breakdown of −5 V, enabling robust operation in negative-rail bias configurations. Its DC current gain remains stable across −40 °C to +150 °C ambient, with h_FE ≥100 at both −10 mA and −100 mA I_C.

V_CE(sat) is specified at −0.25 V (I_C = −100 mA, I_B = −10 mA), supporting efficient saturation in low-dropout switch applications. Thermal resistance R_th(j-a) is 500 K/W on standard FR4 PCB, defining power derating behavior under natural convection.

FAQ

Is PMBTA56-QVL pin-compatible with PMBTA06?

No-PMBTA56-QVL is a PNP transistor while PMBTA06 is its NPN complement; both share identical SOT23 pinout (1=B, 2=E, 3=C), but polarity reversal means direct substitution would invert circuit function and likely cause failure unless topology is redesigned.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA (single pulse, t_p ≤1 ms), but continuous I_B must be limited by thermal constraints. At I_C = −100 mA and h_FE = 100, typical I_B is −1 mA; sustained I_B >−5 mA requires verification against P_tot derating curves.

Does PMBTA56-QVL support wave soldering?

Yes-Nexperia provides dedicated wave soldering footprint data (Fig. 8) for SOT23, specifying 1.4 mm pad width and 2.2 mm spacing. The device meets JEDEC J-STD-020 moisture sensitivity level 1, allowing unlimited floor life before soldering.

How does its h_FE vary with temperature?

h_FE decreases as temperature rises: Fig. 1 shows typical values dropping from ~180 at −40 °C to ~120 at +150 °C (V_CE = −1 V, I_C = −10 mA). Designers should verify minimum h_FE = 100 holds across full operating range per datasheet Fig. 1.
