Product details
Overview
BCR158WE6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ), designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, and AEC-Q101 qualification.
For engineers reviewing the BCR158WE6327HTSA1 datasheet, BCR158WE6327HTSA1 pinout, BCR158WE6327HTSA1 application, or BCR158WE6327HTSA1 equivalent, this part serves as a ready-to-use logic-level PNP switch with built-in base biasing-eliminating external resistor networks in microcontroller-driven load control, LED drivers, and level-shifting interfaces.
Technical Context
This digital transistor integrates two precision on-chip resistors to configure a fixed-current base drive topology, enabling direct connection to CMOS/TTL logic outputs without external components. Its PNP structure supports high-side switching with active-low input control, and its SOT323 package delivers enhanced thermal resistance (RthJS ≤ 105 K/W) versus SOT23 variants.
The device operates across −40 °C to +125 °C junction temperature, with guaranteed hFE ≥ 70 at IC = 5 mA/VCE = 5 V and fT = 200 MHz, supporting fast edge transitions in pulse-width modulated (PWM) and digital signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails. |
| IC | 100 mA - Continuous collector current rating; suitable for driving relays, small solenoids, and indicator LEDs. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Fixed internal bias network provides stable turn-on/turn-off thresholds for logic-compatible operation. |
| fT | 200 MHz - Transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz square waves. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics, including temperature cycling and HTRB. |
| Ptot (TS ≤ 124 °C) | 250 mW - Total power dissipation limit at specified heatsink temperature; defines safe continuous operating envelope. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Emitter terminal - connected to positive rail in high-side switch configuration; referenced to logic ground via load. |
| 2 (Base) | B | Base input node - internally biased through R1/R2 network; accepts TTL/CMOS logic low (≤0.4 V) to activate conduction. |
| 3 (Collector) | C | Collector output - sinks current from load to ground when active; used for driving LEDs, optocouplers, or gate inputs. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum allowable base-emitter reverse voltage for BCR158WE6327HTSA1?
The maximum input reverse voltage (Vi(rev)) is 5 V, defined as the peak reverse voltage that may be applied between base and emitter terminals without risking junction damage or parametric shift. This rating supports safe operation when interfacing with open-drain or actively pulled-up logic buses, and must not be exceeded even transiently in system design.
Does BCR158WE6327HTSA1 require an external pull-down resistor on the base pin?
No. The internal R2 resistor (47 kΩ) provides a defined path from base to emitter, ensuring reliable turn-off when the input is left floating or driven high-impedance. External pull-down is unnecessary and may degrade noise immunity or increase standby current if improperly sized.
Can BCR158WE6327HTSA1 be used in linear amplifier configurations?
No. This device is optimized and characterized exclusively for switching operation. Its hFE variation over IC, lack of linearity data, and absence of small-signal parameters (e.g., rπ, gm) in the datasheet confirm it is not intended for analog amplification. Use dedicated general-purpose PNP transistors like BC807 for such roles.
How does the SOT323 package affect thermal derating compared to SOT23?
The SOT323 package achieves lower junction-to-solder-point thermal resistance (RthJS ≤ 105 K/W vs. ≤ 240 K/W for SOT23), allowing 25% higher continuous power dissipation (250 mW vs. 200 mW) at the same heatsink temperature. This directly extends usable current range in thermally constrained layouts without forced cooling.
