Product details
Overview
BSP60E6327HTSA1 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 is housed in an SOT-223 package and qualified to AEC-Q101 for automotive use.
For engineers reviewing the BSP60E6327HTSA1 datasheet, BSP60E6327HTSA1 pinout, BSP60E6327HTSA1 application, or BSP60E6327HTSA1 equivalent, key selection criteria include VCEO rating, Darlington hFE > 1000, thermal resistance (RthJS ≤ 17 K/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Darlington pair integrates two cascaded PNP transistors on a single die to achieve high DC current gain (hFE = 1000–2000) with low base drive requirements. Its structure enables efficient switching of loads up to 1 A while maintaining low saturation voltage under defined bias conditions.
The device operates with a maximum junction temperature of 150 °C and exhibits fT = 200 MHz at IC = 100 mA, VCE = 5 V, indicating usable bandwidth for moderate-speed digital switching-not RF amplification. Thermal design must account for RthJS ≤ 17 K/W and derated power dissipation above TS = 124 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating range in switching circuits. |
| IC (continuous) | 1 A - Continuous collector current capability; supports medium-power relay, lamp, and solenoid drivers. |
| VCE(sat) | 1.3 V @ IC = 500 mA, IB = 0.55 mA - Low saturation voltage reduces conduction loss and self-heating during on-state operation. |
| hFE | 1000–2000 @ IC = 150–500 mA - High DC current gain minimizes required base drive current, easing microcontroller GPIO interface. |
| RthJS | ≤ 17 K/W - Junction-to-soldering-point thermal resistance; critical for heatsinkless PCB layout with copper pour. |
| fT | 200 MHz @ IC = 100 mA - Transition frequency confirms suitability for <100 kHz switching; not for RF signal amplification. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics, including temperature cycling and HTRB. |
Pinout & Package
Package: SOT-223 (4-pin, standard leaded surface-mount package with exposed thermal pad; pin 1 = Base, pin 2 = Collector, pin 3 = Emitter, pin 4 = Collector - dual collector connection for enhanced current handling and thermal path).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control input; requires ~0.55 mA base current to saturate 500 mA collector load. |
| Pin 2 | Collector | Main high-side current path; electrically tied to Pin 4 for parallel current sharing and improved thermal conduction. |
| Pin 3 | Emitter | Common emitter node; connected to system ground or low-side return in high-side switch configurations. |
| Pin 4 | Collector | Second collector terminal; shares same internal node as Pin 2-used for mechanical stability and thermal relief on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE Darlington architecture | Enables direct drive from 3.3 V/5 V MCU GPIO without external base resistor network or level-shifting. |
| Low VCE(sat) | Reduces power loss to ≤650 mW at 500 mA, minimizing thermal stress in compact layouts. |
| AEC-Q101 qualification | Validates reliability for automotive body electronics, including seat control, HVAC actuators, and lighting modules. |
| SOT-223 thermal pad | Supports ≥1.5 W dissipation at TS ≤ 124 °C when soldered to ≥1 cm² 2-oz copper area. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (J-STD-020, peak 260 °C). |
Applications
| Automotive Door Lock Actuator | Industrial PLC Output Stage |
|---|---|
Use Scenario: Driving 12 V DC solenoid locks in vehicle door modules with PWM-controlled dwell time. IC Role / Device Role / Timing Role: High-side PNP Darlington switch controlling solenoid current path; handles 800 mA peak load with <10 µs turn-on delay. Use Value: Low VCE(sat) limits heat generation during repeated actuation cycles; AEC-Q101 ensures 15-year field reliability. | Use Scenario: Switching 24 V DC indicator lamps and small relays in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Discrete output driver stage interfacing PLC microcontroller to industrial loads; supports 1 A steady-state current. Use Value: High hFE eliminates need for buffer transistors, reducing BOM count and PCB area in space-constrained modules. |
| LED Signage Power Switch | Appliance Motor Control |
Use Scenario: Enabling segmented LED arrays (e.g., dot-matrix displays) in outdoor signage with 24 V supply rails. IC Role / Device Role / Timing Role: Medium-current sink/source switch managing up to 1 A per segment; driven by shift-register outputs. Use Value: Dual-collector SOT-223 footprint improves thermal margin over SO-8 alternatives, enabling higher brightness without forced air cooling. | Use Scenario: Controlling auxiliary 12 V DC brush motors in home appliances (e.g., dishwasher drain pumps, washer spin assist). IC Role / Device Role / Timing Role: Solid-state replacement for electromechanical relays; switched via microcontroller PWM at ≤1 kHz. Use Value: 45 V VCEO provides 2× safety margin against inductive kickback; RthJS ≤ 17 K/W allows operation without heatsink in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP53-16TA | VCEO = 45 V, hFE = 250–630 (lower gain), SOT-223, no AEC-Q101 qualification | Not rated for automotive environments; suitable for cost-sensitive industrial controls only | Select if AEC-Q101 is unnecessary and lower hFE is acceptable with added base drive circuitry |
| MMBT6427LT1G | VCEO = 30 V (lower voltage rating), hFE = 1000–3000, SOT-23 (smaller package, higher RthJA) | Limited to ≤30 V systems; unsuitable for 45 V automotive battery transients | Choose only for space-constrained 24 V non-automotive designs where thermal budget permits SOT-23 mounting |
Compared with BCP53-16TA and MMBT6427LT1G, BSP60E6327HTSA1 uniquely combines AEC-Q101 qualification, 45 V rating, and Darlington-level hFE in SOT-223-making it the sole option for thermally demanding automotive switching where reliability and gain are jointly critical.

FAQ
What is the maximum safe operating voltage for BSP60E6327HTSA1 in automotive 12 V systems?
The BSP60E6327HTSA1 has a VCEO rating of 45 V, providing a 3.75× safety margin over nominal 12 V battery voltage and accommodating ISO 7637-2 pulse 5a (load dump) transients up to 40 V. Operation beyond 45 V risks avalanche breakdown and permanent damage.
Can BSP60E6327HTSA1 replace a standard PNP BJT like BC807 in existing designs?
No-BSP60E6327HTSA1 is a Darlington pair with ~1.9 V VBE(sat) and much higher hFE; substituting it for a single BJT like BC807 will cause excessive base current draw and potential logic-level incompatibility unless the drive circuit is redesigned to accommodate higher VBE and reduced base resistor values.
Is thermal pad soldering required for full 1.5 W power dissipation?
Yes-the 1.5 W Ptot rating assumes the exposed thermal pad (Pin 3 tab) is fully soldered to ≥1 cm² of 2-oz copper on the PCB. Without this, RthJA increases significantly, limiting safe continuous current to ≤600 mA at ambient 70 °C.
Does BSP60E6327HTSA1 support PWM switching at frequencies above 10 kHz?
Yes-its fT = 200 MHz and documented switching times (ton/toff < 1 µs) support clean PWM operation up to 20 kHz. However, VCE(sat) rises slightly at higher frequencies due to minority carrier storage; keep duty cycle ≤80% and ensure adequate base drive to avoid partial saturation.
