Nexperia USA Inc. PBSS5160T,215

Overview

PBSS5160T,215 from Nexperia is a PNP low-V_CEsat transistor in SOT23 package, rated for −60 V V_CEO, −1 A continuous collector current, and 220–330 mΩ R_CEsat at I_C = −1 A / I_B = −100 mA. It serves as a high-efficiency switching element in low-voltage peripheral drivers, automotive load control, and DC-DC converter synchronous rectification stages.

For engineers reviewing the PBSS5160T,215 datasheet, PBSS5160T,215 pinout, PBSS5160T,215 application, or PBSS5160T,215 equivalent, key selection criteria include verified −60 V blocking capability, AEC-Q101 qualification for automotive use, low thermal resistance (312 K/W on 1 cm² FR4 pad), and direct replacement suitability for BCP52/BCX52 in space-constrained PCB layouts.

Technical Context

This PNP bipolar junction transistor employs optimized doping and geometry to achieve low saturation voltage without compromising breakdown robustness. Its −60 V V_CEO and −80 V V_CBO support operation in 48 V automotive and industrial supply rails, while its 150–220 MHz f_T enables stable switching up to several hundred kHz in PWM-driven loads.

The device operates with fixed base-emitter turn-on voltage of −0.82 to −0.9 V and exhibits h_FE = 100–160 at I_C = −1 A, enabling predictable current gain in linear and saturated switching modes. Thermal derating follows defined curves: 1.25 W at T_amb ≤ 25 °C (with 1 cm² collector pad), dropping to zero at 150 °C junction temperature.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current (I_B) is −300 mA per Table 5. However, for reliable continuous operation at I_C = −1 A, the datasheet specifies −100 mA pulsed base drive (tp ≤ 300 µs, δ ≤ 0.02). Sustained DC base current above −50 mA risks thermal runaway due to β degradation at elevated junction temperatures.

Can PBSS5160T,215 replace BCX52 in an existing TO-92 design without PCB changes?

No. PBSS5160T,215 uses SOT23 surface-mount packaging (2.9 mm × 1.3 mm), while BCX52 uses through-hole TO-92 (4.6 mm × 2.9 mm). Direct substitution requires redesigning the footprint, stencil, and assembly process. A drop-in replacement would require a TO-92 variant like PBSS5160X, which is not offered by Nexperia.

Does the AEC-Q101 qualification cover all temperature ranges specified in the datasheet?

Yes. AEC-Q101 qualification includes testing across the full specified ambient temperature range of −65 °C to +150 °C, as well as accelerated stress tests (HTGB, HTRB, TC, UHAST) performed at temperature extremes. The qualification applies to the entire Pb-free SOT23 package construction used in PBSS5160T,215.

What is the typical thermal resistance when mounted on standard FR4 with no extended copper pad?

Per Table 6, R_th(j-a) is 465 K/W for standard FR4 footprint (no extended collector pad). This value assumes single-sided 1 oz copper, tin-plated, per JEDEC 51-3 guidelines. With this mounting, maximum continuous power dissipation drops to 270 mW at 25 °C ambient, requiring careful thermal analysis for >300 mA loads.
