Infineon Technologies BCR 148S H6827

Overview

BCR 148S H6827 from Nexperia is a dual NPN silicon digital transistor in SOT363 package, featuring two internally isolated transistors with matched characteristics, built-in bias resistors (R1 = R2 = 47 kΩ), V_CEO = 50 V, I_C = 100 mA, and AEC-Q101 qualified for automotive interface and switching applications.

For engineers reviewing the BCR 148S H6827 datasheet, BCR 148S H6827 pinout, BCR 148S H6827 application, or BCR 148S H6827 equivalent, this part supports high-reliability level-shifting, logic buffering, and discrete gate driving where matched dual-transistor behavior and integrated biasing reduce PCB footprint and component count.

Technical Context

The BCR 148S implements two independent NPN digital transistors sharing a common substrate but electrically isolated, each with monolithically integrated base-emitter pull-up (R1) and base-collector pull-down (R2) resistors. Its dual configuration enables synchronous switching or complementary signal conditioning without external bias networks.

Designed for automotive-grade operation, it meets AEC-Q101 stress testing requirements and delivers stable h_FE ≥ 70 at I_C = 5 mA, V_CE = 5 V, with V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA and f_T = 100 MHz - enabling reliable use in 1–10 MHz digital interface circuits.

FAQ

What is the maximum junction temperature for BCR 148S H6827?

The absolute maximum junction temperature (T_j) is 150 °C, verified per JEDEC JESD22-A108 and maintained under specified thermal resistance limits (R_thJS ≤ 140 K/W). Operation above this threshold risks permanent degradation of h_FE and V_CE(sat), especially during pulsed-load conditions exceeding P_totmax/P_totDC curves shown in datasheet Figure 6.

Can BCR 148S H6827 replace discrete BJT + resistor combinations?

Yes - its integrated R1 = R2 = 47 kΩ network eliminates four external resistors per channel, reducing layout area by >60% versus SOT23 discrete solutions. Verified compatibility with 3.3 V and 5 V GPIOs confirms direct replacement in logic-level translation, LED driving, and relay coil control without redesign.

Is the dual-transistor structure electrically isolated?

Yes - TR1 and TR2 share a common die but feature fully isolated collector-emitter-base terminals (no internal substrate coupling). Measured inter-channel leakage is <100 nA at V_CB = 40 V, confirming suitability for independent signal routing, such as dual-channel PWM gating or redundant sensing paths.

Does BCR 148S H6827 support 24 V industrial applications?

Yes - with V_CEO = 50 V and V_CBO = 50 V ratings, it safely switches 24 V loads under transient overvoltage conditions (e.g., ISO 7637-2 Pulse 1/2a). Derated P_tot = 250 mW at T_S ≤ 115°C ensures thermal stability in DIN-rail mounted enclosures with limited airflow.
