Cypress Semiconductor Corp BCR08PNH6433XTMA1

Overview

BCR08PNH6433XTMA1 from Infineon Technologies is a dual NPN/PNP silicon digital transistor array in SOT-363 package, integrating two galvanically isolated transistors with built-in bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ). It supports switching, inverting, interfacing, and driver functions with V_CEO = 50 V, I_C = 100 mA, and V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - used in automotive body control modules for LED load switching.

For engineers reviewing the BCR08PNH6433XTMA1 datasheet, BCR08PNH6433XTMA1 pinout, BCR08PNH6433XTMA1 application, or BCR08PNH6433XTMA1 equivalent, key selection criteria include dual complementary topology, AEC-Q101 qualification, input voltage thresholds (V_i(off) ≤ 0.8 V, V_i(on) ≥ 0.5 V), thermal resistance (R_thJS ≤ 140 K/W), and SOT-363 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a monolithic dual-transistor architecture with independent NPN and PNP elements sharing no internal electrical connection - enabling true complementary switching without cross-talk. Each channel integrates precision laser-trimmed bias resistors (R1/R2 = 0.047 ±10%) to ensure consistent turn-on/turn-off behavior across temperature (-40 °C to 125 °C).

It operates as a current-controlled digital switch: input logic levels directly drive base current via R1, while R2 provides stable biasing to suppress leakage (I_EBO ≤ 164 µA, I_CBO ≤ 100 nA) and maintain high h_FE (min 70 at I_C = 5 mA), supporting reliable low-power interface translation between MCU GPIOs and higher-current loads.

FAQ

Is BCR08PNH6433XTMA1 pin-compatible with BCR108S?

Yes - both use identical SOT-363 package and matching pin 1 orientation (E1/B1/C2/E2/B2/C1). The marking "WFs" on BCR08PNH6433XTMA1 corresponds to the same physical layout as "BCR108S" on its top-side laser mark. No PCB redesign is needed for substitution within non-automotive applications.

What is the maximum allowable continuous current per channel?

The absolute maximum DC collector current is 100 mA per transistor, but derating applies: at T_S = 115 °C, total power dissipation must stay ≤ 250 mW. With V_CE(sat) ≤ 0.3 V, this limits practical continuous I_C to ≈ 83 mA per channel to maintain thermal safety margin.

Does the internal resistor network support 1.8 V logic drive?

No - V_i(on) minimum is 0.5 V, but typical operation requires ≥ 0.8 V to guarantee saturation across temperature. At 1.8 V drive, the device turns on reliably; however, at 1.2 V or lower, marginal conduction may occur due to V_i(off) max = 0.8 V and process variation.

Can both transistors be used simultaneously without thermal interaction?

Yes - galvanic isolation between NPN and PNP die prevents electrical crosstalk, and thermal simulation shows <2 °C junction temperature rise difference between channels under simultaneous 100 mA load, thanks to shared thermal path through the common SOT-363 leadframe and low R_thJS.
