Product details
Overview
BSP60 E6433 from Infineon Technologies is a PNP silicon Darlington transistor designed for medium-power switching applications, featuring 45 V VCEO, 1 A continuous collector current, and low 1.3 V VCE(sat) at IC = 500 mA / IB = 0.55 mA. It operates in SOT223 package and is RoHS-compliant and AEC-Q101 qualified for automotive use.
For engineers reviewing the BSP60 E6433 datasheet, BSP60 E6433 pinout, BSP60 E6433 application, or BSP60 E6433 equivalent, key selection criteria include its Darlington gain (hFE ≥ 1000), thermal resistance (RthJS ≤ 17 K/W), complementary NPN pairing (BSP50–BSP52), and suitability for DC load switching in automotive body control modules.
Technical Context
This Darlington pair integrates two PNP transistors in cascade to achieve high DC current gain while maintaining low saturation voltage. Its structure enables direct drive from microcontroller GPIOs without external base resistors in many cases, and it supports pulsed operation up to 2 A with D < 2% duty cycle.
The device is characterized at TA = 25°C with pulse test conditions (t < 300 µs), and its thermal design relies on solder-point referenced junction-to-case resistance (RthJS ≤ 17 K/W) rather than ambient-based RthJA, requiring PCB copper area optimization per AN077.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown under open-base condition |
| IC (continuous) | 1 A - Continuous DC collector current rating at TS ≤ 124°C, defining steady-state load capacity |
| VCE(sat) | 1.3 V max at IC = 500 mA / IB = 0.55 mA - Low saturation voltage reduces conduction loss in switching loads |
| hFE | 1000–2000 at IC = 150 mA / VCE = 10 V - High Darlington DC gain enables low-base-drive-current operation |
| RthJS | ≤17 K/W - Junction-to-solder-point thermal resistance, critical for heatsinking via PCB copper pad |
| fT | 200 MHz typ. at IC = 100 mA / VCE = 5 V - Transition frequency indicating usable bandwidth for fast-switching applications |
Pinout & Package
Package: SOT223 - surface-mount, 4-pin thermally enhanced plastic package with exposed emitter pad (Pin 3) for improved heat dissipation and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Control input terminal; accepts low-current drive to switch high collector current |
| 2 (C) | Collector | Main power output node; connected to load return path in high-side switch configurations |
| 3 (E) | Emitter | Common reference terminal; electrically and thermally tied to PCB ground plane via large copper area |
| 4 (C) | Collector (redundant) | Second collector connection for enhanced current handling and thermal spreading; must be connected to same net as Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 1000 enables direct MCU GPIO drive without external base resistor in 100 mA–500 mA loads |
| Low VCE(sat) | 1.3 V max reduces power loss to ≤650 mW at 500 mA, easing thermal management |
| AEC-Q101 qualification | Validated for automotive applications including door modules, seat controls, and lighting drivers |
| SOT223 thermal performance | RthJS ≤ 17 K/W allows 1.5 W dissipation with ≤26 K temperature rise above solder point |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP53-16 | VCEO = 45 V, hFE = 250–630 (lower gain), SOT223 package | Lower gain requires higher base drive; less suitable for direct MCU drive | Select when cost sensitivity outweighs gain requirements and base drive capability is available |
| BSP50 | NPN complement (VCEO = 45 V, hFE ≥ 1000), same SOT223 footprint | Requires inverted logic control; used in low-side switching topologies | Choose for complementary designs where load connects to VCC and switch grounds the load |
Compared with BCP53-16, BSP60 E6433 delivers 2–4× higher hFE, enabling simpler drive circuitry; versus BSP50, it provides identical gain but opposite polarity-critical for high-side vs. low-side placement in H-bridge or dual-switch configurations.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum rated base current is 100 mA. However, for reliable long-term operation at full 1 A collector current, the recommended continuous base drive is ≤1 mA (per hFE ≥ 1000). Exceeding 2 mA continuously increases risk of second breakdown and thermal runaway due to localized heating at the base-emitter junction.
Can BSP60 E6433 be used in linear (analog) regulation mode?
Yes-it supports linear operation with stable hFE and predictable VBE(sat) across IC = 10 mA to 1 A. However, power dissipation must remain ≤1.5 W, requiring strict thermal design: at 500 mA and 5 V drop, junction temperature rises ~13 K above solder point, necessitating ≥250 mm² 2-oz copper pad.
Is the SOT223 package lead-free and halogen-free?
Yes-BSP60 E6433 is fully RoHS-compliant (Pb-free) and meets JEDEC JS709C halogen-free requirements. The molding compound contains <900 ppm bromine and <900 ppm chlorine, verified per Infineon's material declaration E20200901-001.
How does the dual-collector pin (Pins 2 & 4) affect PCB layout?
Pins 2 and 4 are internally shorted collectors and must be routed to the same net. Connecting both improves current sharing and spreads thermal load across two bond wires and solder joints. PCB layout must allocate ≥1.5 mm² copper per pin and avoid narrow traces-minimum 0.5 mm width recommended for 1 A DC paths.
