Infineon Technologies BCR 162T E6327

Overview

BCR 162T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 4.7 kΩ), designed for low-power switching, level translation, and interface driver functions in compact logic circuits. It supports 50 V V_CEO, 100 mA I_C, 0.3 V V_CE(sat) at 10 mA/0.5 mA drive, and operates up to 150 °C junction temperature - used in portable sensor interfaces and microcontroller GPIO expansion.

For engineers reviewing the BCR 162T E6327 datasheet, BCR 162T E6327 pinout, BCR 162T E6327 application, or BCR 162T E6327 equivalent, key selection criteria include guaranteed input resistor matching (R1/R2 = 0.9–1.1), SC75 package thermal resistance (R_thJS ≤ 165 K/W), and verified 200 MHz f_T performance under 10 mA/5 V conditions.

Technical Context

This PNP digital transistor integrates two precision 4.7 kΩ bias resistors to enable single-resistor base drive, eliminating external components in saturated-switch configurations. Its common-emitter DC current gain h_FE ≥ 20 at I_C = 5 mA ensures reliable turn-on with microcontroller-level output currents.

The device features low V_CE(sat) (≤ 0.3 V) and high f_T (typ. 200 MHz), supporting both DC switching and moderate-frequency signal inversion up to ~10 MHz in buffered logic stages. Input off voltage Vi(off) ≤ 1.5 V guarantees clean cutoff under TTL-compatible thresholds.

Key Specifications

FAQ

What is the maximum continuous collector current for BCR 162T E6327 at 70 °C ambient?

At T_A = 70 °C, derating begins at T_S = 109 °C per datasheet Figure 5. With R_thJS ≤ 165 K/W, allowable P_tot drops to ~160 mW. Using V_CE(sat) ≤ 0.3 V, maximum continuous I_C is approximately 530 mA - but absolute maximum rating remains 100 mA per Absolute Maximum Ratings table, limiting practical use to 100 mA regardless of thermal headroom.

Can BCR 162T E6327 replace a standard PNP BJT like BC807 in a switching application?

Yes, but only if the circuit incorporates the internal bias network. Unlike BC807, BCR 162T E6327 has built-in R1 and R2 resistors tied between base and emitter. Direct substitution requires removing external base resistors and verifying that the resulting base current (≈ (V_IN − V_BE)/R1) achieves sufficient h_FE × I_C drive without overloading the source.

Is the SC75 package of BCR 162T E6327 compatible with automated optical inspection (AOI)?

Yes. The SC75 package has defined gull-wing lead geometry (0.4 mm pitch, 0.2 mm width, 0.65 mm length), documented in Infineon's package outline drawing. Its coplanarity < 0.1 mm and matte tin finish meet IPC-A-610 Class 2 requirements, enabling reliable AOI detection of solder joint integrity and lateral offset during SMT line inspection.

Does BCR 162T E6327 support pulsed operation beyond its DC current rating?

Yes - per Figure 6, permissible pulse load ratio P_tot(max)/P_tot(DC) reaches 10× for t_p < 10 µs at duty cycle D = 0.005. At I_C = 200 mA (2× rated DC), safe pulse width is ≤ 5 µs. This enables brief inrush current handling for capacitive loads or relay coil energization without exceeding junction temperature limits.
