Nexperia USA Inc. PMBTA92,215

Overview

PMBTA92,215 from Nexperia is a PNP high-voltage bipolar junction transistor in SOT23 package, rated for −300 V V_CEO, −100 mA I_C, and 250 mW P_tot. It serves as a high-voltage switching or amplification device in off-hook detection circuits, line interface modules, and telecom signal conditioning stages.

For engineers reviewing the PMBTA92,215 datasheet, PMBTA92,215 pinout, PMBTA92,215 application, or PMBTA92,215 equivalent, key selection criteria include verified −300 V breakdown rating, SOT23 footprint compatibility, DC current gain (h_FE ≥ 40 at −10 mA), thermal resistance (R_th(j-a) = 500 K/W), and NPN complement availability (PMBTA42).

Technical Context

This discrete PNP transistor operates in active or saturation mode with fixed polarity biasing-base-emitter forward-biased and collector-emitter reverse-biased up to −300 V. Its low leakage (I_CBO ≤ −250 nA) and stable h_FE across −1 mA to −30 mA support precision analog switching in high-impedance telephony interfaces.

The device uses silicon planar epitaxial technology with optimized doping profiles to sustain high collector-base voltage while maintaining usable gain at low currents. Its SOT23 package enables surface-mount integration into space-constrained line-card PCBs without compromising thermal derating above 25 °C ambient.

FAQ

Is PMBTA92,215 pin-compatible with PMBTA42?

No-PMBTA92,215 is a PNP transistor with pinout Base–Emitter–Collector (1–2–3), while PMBTA42 is its NPN complement with identical SOT23 package but reversed polarity and complementary pin function. They share footprint and mounting, but circuit design must account for opposite biasing and current flow direction.

What is the maximum safe operating temperature for PMBTA92,215?

The absolute maximum junction temperature is 150 °C, and storage temperature range is −65 °C to +150 °C. At ambient temperatures above 25 °C, power dissipation must be derated linearly using R_th(j-a) = 500 K/W; full 250 mW rating applies only at T_amb ≤ 25 °C on standard FR4 PCB.

Can PMBTA92,215 replace BCW68G in existing designs?

Only with circuit validation: BCW68G has V_CEO = −100 V and h_FE = 100–300, whereas PMBTA92,215 offers −300 V rating but lower typical h_FE. The higher voltage margin is beneficial, but base drive may require adjustment due to gain differences and saturation voltage variation.

Does PMBTA92,215 support wave soldering?

Yes-Nexperia provides dedicated wave soldering footprint data (Fig. 3) with solder land dimensions 2.8 mm × 4.5 mm, 1.4 mm × 1.4 mm pads, and recommended transport direction. Thermal profile must respect peak temperature ≤ 260 °C and dwell time ≤ 10 seconds per JEDEC J-STD-020.
