Product details

Overview

BSP60 from Infineon Technologies is a PNP silicon Darlington transistor designed for medium-power switching applications, featuring 45 V V_CEO, 1 A continuous collector current, 1.5 W total power dissipation at T_S ≤ 124 °C, and low 1.3 V V_CE(sat) at I_C = 500 mA / I_B = 0.55 mA - used in automotive body control modules for relay and lamp driver stages.

For engineers reviewing the BSP60 datasheet, BSP60 pinout, BSP60 application, or BSP60 equivalent, key selection criteria include verified Darlington gain (h_FE ≥ 1000 at I_C = 150 mA), thermal resistance (R_thJS ≤ 17 K/W), RoHS-compliant SOT223 package, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

The BSP60 implements a monolithic PNP Darlington pair with integrated base-emitter resistor network enabling direct TTL/CMOS-level drive. Its high DC current gain (h_FE = 1000–2000) and low saturation voltage reduce base drive requirements and conduction losses in discrete load-switching circuits.

It operates with V_CEO = 45 V, V_CBO = 60 V, and V_EBO = 5 V, supporting robust blocking capability in 12 V automotive systems. Switching performance is characterized by f_T = 200 MHz (typ.) and defined turn-on/turn-off timing under pulsed conditions (t_p < 300 µs, duty < 2%).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - maximum safe collector-emitter voltage before breakdown in open-base configuration
I_C (continuous)	1 A - continuous collector current rating at T_S ≤ 124 °C, defining steady-state load-handling capacity
V_CE(sat)	1.3 V max at I_C = 500 mA / I_B = 0.55 mA - low saturation voltage minimizes power loss in on-state switching
h_FE	1000 min at I_C = 150 mA / V_CE = 10 V - high Darlington current gain reduces required base drive current
R_thJS	≤ 17 K/W - junction-to-solder-point thermal resistance enables reliable heat transfer to PCB copper pour
f_T	200 MHz typ. at I_C = 100 mA / V_CE = 5 V - usable for moderate-speed switching up to ~100 kHz with margin

Pinout & Package

Package: SOT223 - surface-mount, thermally enhanced 4-pin plastic package with exposed emitter pad for improved heat dissipation and mechanical stability on PCB.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base	Control input terminal; accepts TTL/CMOS-compatible drive due to internal Darlington structure
2 (C)	Collector	Main current sink node; connected to load return path in high-side switch configurations
3 (E)	Emitter	Power output node; electrically tied to PCB thermal pad for low-impedance heat path
4 (C)	Collector (redundant)	Second collector connection for enhanced current handling and thermal distribution across package leads

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including temperature cycling, humidity, and mechanical shock per stress test standard
Pb-free (RoHS compliant)	Meets EU Directive 2011/65/EU; no lead in solderable terminations or mold compound
Complementary NPN types available	BSP50–BSP52 series enable balanced push-pull or H-bridge designs without cross-manufacturer sourcing
Low V_CE(sat) at high I_C	1.8 V max at I_C = 1 A / I_B = 1 mA - reduces conduction loss in 12 V lamp/relay drivers

Applications

Automotive Lamp Driver

Industrial Relay Interface

Use Scenario: Driving 12 V halogen or LED headlamp circuits in body control units with PWM dimming capability.

IC Role / Device Role / Timing Role: High-current PNP Darlington switch controlling lamp anode connection to battery rail.

Use Value: Delivers 1 A continuous current with <1.3 V drop, minimizing thermal rise and enabling compact heatsinkless layout.

Use Scenario: Isolating microcontroller GPIO from 24 V industrial relay coils in PLC I/O modules.

IC Role / Device Role / Timing Role: Medium-power interface transistor providing galvanic separation and current amplification.

Use Value: High h_FE (≥1000) allows direct 3.3 V MCU drive without external base resistor network.

DC Motor Brake Control

Power Supply Enable Switch

Use Scenario: Shorting motor terminals during dynamic braking in 24 V brushed DC motor controllers.

IC Role / Device Role / Timing Role: Low-saturation switch placed between motor windings and ground to dissipate kinetic energy as heat.

Use Value: R_thJS ≤ 17 K/W supports transient 2 A peak current (t_p ≤ 10 ms) without junction overheating.

Use Scenario: Enabling/disabling auxiliary 5 V or 3.3 V LDO outputs in multi-rail embedded power systems.

IC Role / Device Role / Timing Role: High-side enable switch controlling input to downstream regulators via collector-emitter path.

Use Value: V_CEO = 45 V provides 2× margin over 24 V supply rails, ensuring long-term reliability under load dump transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP Darlington switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP53	V_CEO = 45 V, I_C = 1 A, but h_FE min = 250 (not Darlington); higher V_CE(sat) (~0.7 V at 500 mA)	Requires external base resistor and higher drive current; unsuitable for direct logic-level drive	Select only if lower saturation voltage is not critical and base drive capability is sufficient
BSP52	NPN complement; identical package, pinout, and ratings except polarity; V_CEO = 45 V, I_C = 1 A, h_FE ≥ 1000	Used in low-side switching; requires inverted control signal and different biasing topology	Choose for complementary push-pull or H-bridge designs where both polarities are needed

Compared with BCP53, BSP60 delivers 4× higher current gain and logic-compatible drive, while versus BSP52 it provides native high-side switching capability without level-shifting circuitry - critical for automotive load grounding architectures.

FAQ

What is the maximum allowable junction temperature for BSP60?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of the Darlington structure and reduced long-term reliability, especially under sustained high-current or elevated ambient conditions.

Can BSP60 be used in linear amplifier mode?

No - BSP60 is optimized and characterized exclusively for switching operation. Its Darlington architecture exhibits poor linearity, high thermal sensitivity, and undefined small-signal parameters; use only in saturated on/off states per datasheet switching test conditions.

Is the SOT223 package lead-free and compatible with standard reflow profiles?

Yes - BSP60 uses a Pb-free (RoHS-compliant) SOT223 package qualified for standard lead-free reflow soldering (J-STD-020D), with peak temperature tolerance up to 260 °C for 30 seconds and thermal profile compatibility verified per Infineon's application note AN077.

How does BSP60 handle load dump transients in automotive 12 V systems?

BSP60 withstands load dump events up to 45 V (V_CEO rating) with margin, but requires external clamping (e.g., TVS diode) for full ISO 7637-2 Pulse 5a compliance. Its AEC-Q101 qualification confirms robustness against repetitive surge stress when properly protected in system design.
