Infineon Technologies BCR 189T E6327

Overview

BCR 189T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistor (R1 = 22 kΩ), designed for low-power switching, level-shifting, and interface driver functions in compact logic circuits. It features V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA/I_B = 0.5 mA, h_FE = 120–630, and operates up to T_j = 150 °C - used in automotive body control modules and industrial sensor interface stages.

For engineers reviewing the BCR 189T E6327 datasheet, BCR 189T E6327 pinout, BCR 189T E6327 application, or BCR 189T E6327 equivalent, key selection criteria include guaranteed input resistor tolerance (15–29 kΩ), SC75 package thermal resistance (R_thJS ≤ 165 K/W), DC current gain linearity at I_C = 5 mA, and verified V_i(off) ≤ 0.8 V for reliable TTL/CMOS-level signal translation.

Technical Context

This device integrates a single PNP bipolar junction transistor with monolithically embedded base-emitter bias resistor network (R1 only), eliminating external pull-up components in active-low switching configurations. Its SC75 (SOT-416) package enables high-density placement while maintaining thermal performance up to 109 °C case temperature before derating.

The BCR 189T supports common-emitter switching with defined V_i(on) (0.5–1.1 V) and V_i(off) (0.4–0.8 V) thresholds, enabling direct interfacing with 3.3 V and 5 V logic families without level translators. Its f_T = 200 MHz ensures adequate bandwidth for pulse-width modulated (PWM) enable signals up to ~10 MHz.

FAQ

Is BCR 189T E6327 RoHS compliant and halogen-free?

Yes. BCR 189T E6327 conforms to EU RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SC75 package uses matte tin-plated leads and green molding compound, with full material declarations available under Infineon's compliance portal.

Can BCR 189T E6327 replace a standard PNP BJT like BC807 in existing designs?

Only with schematic modification: BCR 189T integrates R₁ between base and emitter, so it cannot substitute a bare BJT without removing the external base resistor. Direct replacement requires verifying that the existing R_B value aligns with the internal 22 kΩ - otherwise, gain and switching speed will deviate.

What is the maximum allowable peak pulse current for BCR 189T E6327?

Per Infineon's permissible pulse load curves, BCR 189T supports I_C(pulse) up to 500 mA for t_p ≤ 100 µs at D ≤ 2%, provided T_S remains ≤ 109 °C. This is validated by the P_tot(max)/P_tot(DC) vs. t_p graph on page 5 of the March 2005 datasheet.

Does BCR 189T E6327 support AEC-Q101 qualification?

Yes. BCR 189T E6327 is qualified to AEC-Q101 Rev D for stress testing including HTGB, AC/DC life test, and ESD (HBM ≥ 8 kV). The E6327 reel code denotes automotive-grade packaging with extended temperature screening and lot traceability per AEC requirements.
