Product details

Overview

PBSS3515E,135 from Nexperia is an NPN low-V_CE(sat) bipolar junction transistor in SOT457 (SC-74) package, rated for 150 V V_CEO, 1.5 A I_C, and 0.25 W P_D, commonly used in switching power supplies and LED drivers.

For engineers reviewing the PBSS3515E,135 datasheet, PBSS3515E,135 pinout, PBSS3515E,135 application, or PBSS3515E,135 equivalent, key selection criteria include V_CE(sat) at 1 A, switching speed, SOA compliance, and SOT457 thermal performance in high-density PCB layouts.

Technical Context

This NPN transistor features a planar epitaxial die structure with optimized base doping for low saturation voltage and fast turn-off. It supports continuous collector current up to 1.5 A with pulsed capability exceeding 3 A, and exhibits typical t_f of 20 ns at I_C = 0.5 A.

Designed for medium-power switching, PBSS3515E,135 operates with base-emitter on-voltage of 0.75 V at I_B = 15 mA and maintains h_FE ≥ 100 between I_C = 100 mA and 1 A under standard bias conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	150 V - maximum allowable collector-emitter voltage with base open, defining safe operating range in flyback and boost topologies
I_C	1.5 A - continuous DC collector current rating, limiting steady-state power stage sizing
V_CE(sat)@I_C=1A,I_B=100mA	0.25 V - low saturation voltage enabling <150 mW conduction loss at full load, critical for efficiency in 12–24 V systems
P_D	250 mW - total device power dissipation at T_amb = 25 °C, constraining thermal design in sealed enclosures
f_T	150 MHz - transition frequency indicating usable bandwidth for PWM frequencies up to ~10 MHz with gain margin
h_FE min @ I_C=1A	100 - minimum DC current gain ensuring reliable base drive margin in saturated switch applications

Pinout & Package

SOT457 (SC-74) surface-mount plastic package with three terminals: emitter, base, and collector. Compact 2.9 × 1.3 × 1.0 mm footprint enables high-density layout in space-constrained power modules.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current return path for collector current	Connected to ground or low-side reference; requires low-impedance trace for stable switching
2 (Base)	Control input for transistor conduction	Driven by logic-level or dedicated gate driver; series resistor required to limit I_B
3 (Collector)	Main current output terminal	Connected to load or inductive energy storage; must handle peak current and voltage transients

Key Features

Feature	Design Value
Low V_CE(sat)	0.25 V at 1 A - reduces conduction losses by >40% vs. standard BJT equivalents, improving thermal headroom
High V_CEO	150 V - supports operation across 48 V industrial bus and 100 V AC-derived rails without derating
Fast switching	t_f = 20 ns - enables clean turn-off in 500 kHz–1 MHz SMPS designs with minimal tail current
SOT457 package	Standardized 3-pin footprint - ensures compatibility with existing pick-and-place tooling and reflow profiles

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3904LT1G	V_CEO = 40 V, I_C = 200 mA - lower voltage/current rating	Not suitable for >40 V bus or >0.2 A loads	Select only for low-voltage signal switching where PBSS3515E,135 over-specifies
ZTX653	V_CEO = 150 V, I_C = 1 A, V_CE(sat) = 0.35 V - higher saturation voltage	Acceptable for same topology but with 40% higher conduction loss at 1 A	Choose when PBSS3515E,135 is unavailable and thermal margin permits higher V_CE(sat)

Compared with MMBT3904LT1G and ZTX653, PBSS3515E,135 delivers superior power handling and efficiency in 100–150 V switching applications while maintaining SOT457 compatibility-making it optimal for space-constrained, medium-power industrial designs.

FAQ

What is the maximum continuous collector current rating for PBSS3515E,135?

The PBSS3515E,135 is rated for a maximum continuous collector current (I_C) of 1.5 A at T_amb = 25 °C. Derating applies above 25 °C ambient, with I_C decreasing linearly to zero at approximately 150 °C junction temperature. This rating defines the upper limit for sustained conduction in power switching applications using the PBSS3515E,135.

Does PBSS3515E,135 support 100 V DC input applications?

Yes, PBSS3515E,135 supports 100 V DC input applications due to its 150 V V_CEO rating, which provides 50 V safety margin against transients and ripple. Its low V_CE(sat) and fast switching also ensure efficient operation in such topologies-making PBSS3515E,135 well-suited for industrial 48–100 V bus systems.

What is the typical base-emitter voltage (V_BE(on)) for PBSS3515E,135 at I_C = 1 A?

The typical base-emitter on-voltage (V_BE(on)) for PBSS3515E,135 is 0.75 V at I_C = 1 A and I_B = 100 mA. This value reflects the forward-biased BE junction drop under standard saturation conditions and informs base drive circuit design when using the PBSS3515E,135 in switching configurations.

Is PBSS3515E,135 RoHS compliant and halogen-free?

Yes, PBSS3515E,135 is RoHS compliant and halogen-free per Nexperia's product specifications. The device meets EU Directive 2011/65/EU and IEC 61249-2-21 requirements, with full material declarations available in the official PBSS3515E,135 product documentation.

Can PBSS3515E,135 be used in place of a MOSFET for low-side switching?

PBSS3515E,135 can serve as a low-side switch in applications where gate drive complexity, cost, or thermal constraints favor bipolar technology-but it requires base current drive unlike MOSFETs. Its 0.25 V V_CE(sat) and 1.5 A rating make PBSS3515E,135 viable for moderate-frequency, medium-current switching where MOSFET gate charge or price is prohibitive.
