Nexperia USA Inc. PBSS2515M,315

Overview

PBSS2515M,315 from NXP Semiconductors is a 15 V, 0.5 A NPN low-V_CEsat BISS transistor in SOT883 package, designed for high-efficiency switching in space-constrained power management and peripheral driver circuits. Confirmed parameters: V_CEO = 15 V, I_C = 500 mA (DC), R_CEsat < 500 mΩ, V_CEsat = 250 mV @ 500 mA/50 mA, h_FE = 90 @ 500 mA. Used in LCD backlighting and battery charger switch stages.

For engineers reviewing the PBSS2515M,315 datasheet, PBSS2515M,315 pinout, PBSS2515M,315 application, or PBSS2515M,315 equivalent, key selection criteria include ultra-low saturation voltage, thermal resistance (R_{th j-a} = 290 K/W with 1 cm² collector pad), SOT883 footprint compatibility, and verified BISS architecture for reduced conduction loss in low-voltage DC-DC and load-switching designs.

Technical Context

This NPN transistor employs Breakdown-Induced Saturation Switch (BISS) technology to achieve sub-250 mV V_CEsat at 500 mA while maintaining h_FE ≥ 90. Its design targets low-voltage (<15 V) switching where minimal voltage drop and heat generation are critical.

It operates with fixed base-emitter drive logic (IC/IB = 20 typical), supports pulsed peak current up to 1 A (δ ≤ 20%, t_p ≤ 30 ms), and delivers f_T = 420 MHz - enabling fast turn-on/turn-off in PWM-controlled loads like relays and LED strings.

Key Specifications

FAQ

What is the maximum continuous collector current for PBSS2515M,315?

The maximum continuous collector current (I_C) is 500 mA at T_amb ≤ 25 °C with standard FR4 mounting (60 μm copper strip). At elevated ambient temperatures or reduced copper area, derating applies per the 250 mW P_tot limit and R_{th j-a} = 500 K/W free-air value.

Can PBSS2515M,315 replace a standard general-purpose NPN transistor like BC847?

No - PBSS2515M,315 is optimized for low-V_CEsat switching, not linear amplification. Its h_FE drops to 90 at 500 mA (vs. BC847's 110–800 at 2 mA), and its V_CEsat is 250 mV (vs. BC847's ~600 mV). Substitution requires verifying base drive capability and thermal margin in the target circuit.

Is reflow soldering mandatory for PBSS2515M,315?

Yes - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" due to the SOT883 package's leadless construction and thermal sensitivity. Hand soldering risks pad delamination, solder bridging, or thermal damage to the die; stencil-printed paste with controlled ramp/soak/reflow profile is required.

What is the PNP complement part number for PBSS2515M,315?

The official PNP complement is PBSS3515M, specified with matching V_CEO = –15 V, I_C = –500 mA, and comparable V_CEsat and R_CEsat performance. It shares the same SOT883 package and thermal characteristics, enabling complementary push-pull or H-bridge configurations.
