Product details
Overview
BCR35PNH6433XTMA1 from Infineon Technologies is a dual NPN/PNP silicon digital transistor array in SOT-363 package, integrating bias resistors (R1 = 10 kΩ, R2 = 47 kΩ) for direct logic-level switching. It supports 50 V VCEO, 100 mA IC, 0.3 V VCE(sat) at 10 mA/0.5 mA drive, and operates across –65 °C to +150 °C. Used in automotive body control modules for LED driver and relay interface circuits.
For engineers reviewing the BCR35PNH6433XTMA1 datasheet, BCR35PNH6433XTMA1 pinout, BCR35PNH6433XTMA1 application, or BCR35PNH6433XTMA1 equivalent, key selection criteria include guaranteed dual-channel isolation, AEC-Q101 qualification, built-in resistor ratio (R1/R2 = 0.21), thermal resistance ≤140 K/W, and compatibility with 3.3 V/5 V microcontroller GPIOs.
Technical Context
This device integrates two galvanically isolated bipolar transistors - one NPN and one PNP - within a single SOT-363 package, eliminating external biasing components. Each channel features monolithically integrated R1 (10 kΩ) and R2 (47 kΩ) resistors enabling direct connection to digital logic outputs without external pull-up/down networks.
It delivers matched DC current gain (hFE ≥ 70 at IC = 5 mA, VCE = 5 V) and low saturation voltage (VCE(sat) ≤ 0.3 V) for both polarities under identical drive conditions, supporting bidirectional signal inversion and complementary switching in compact space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports 24 V automotive supply rail with 2× safety margin |
| IC | 100 mA - drives medium-power LEDs or small-signal relays directly |
| VCE(sat) | ≤ 0.3 V @ IC = 10 mA, IB = 0.5 mA - minimizes conduction loss in high-duty-cycle switching |
| R1 / R2 | 10 kΩ / 47 kΩ - provides stable input threshold (Vi(on) = 0.5–1.4 V) compatible with TTL/CMOS logic |
| fT | 150 MHz typ. - enables reliable operation up to ~10 MHz square-wave switching |
| Tj max | 150 °C - qualified for under-hood automotive environments per AEC-Q101 |
| RthJS | ≤ 140 K/W - allows 250 mW total dissipation at TS = 115 °C with standard PCB copper area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual digital transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR32PNH6433XTMA1 | Same SOT-363 package, but R1 = 4.7 kΩ, R2 = 47 kΩ → lower Vi(on) threshold (~0.3 V) | Better suited for 1.8 V logic interfaces; higher base current draw at same VIN | Select when driving from ultra-low-voltage MCUs or requiring faster turn-on at marginal input voltages |
| BCR37PNH6433XTMA1 | R1 = 22 kΩ, R2 = 47 kΩ → higher Vi(on) threshold (~1.0–1.8 V); lower base current consumption | Improved noise immunity in electrically noisy engine compartments; slower edge rates | Select for robustness in high-EMI zones where false triggering must be minimized |
Compared with BCR35PNH6433XTMA1, BCR32PN offers lower input threshold for 1.8 V systems but draws more base current, while BCR37PN trades speed for noise immunity - all three share identical pinout, thermal performance, and AEC-Q101 qualification.

FAQ
Is BCR35PNH6433XTMA1 pin-compatible with standard SOT-363 discrete transistors?
No - it uses a proprietary pin assignment (E1-B1-C2-E2-B2-C1) optimized for dual-channel digital operation, differing from generic NPN/PNP SOT-363 placements. Layout must follow Infineon's marking diagram showing "W1s" orientation corresponding to pin 1. Substitution requires schematic and footprint revision.
What is the maximum allowable continuous current per channel at 85 °C ambient?
At TA = 85 °C with standard JEDEC 2-layer board, derated Ptot ≈ 180 mW permits IC ≤ 85 mA per channel assuming VCE(sat) = 0.3 V. Full 100 mA rating applies only at TS = 115 °C with adequate copper pour and thermal vias.
Does this device support PWM switching at 25 kHz for LED dimming?
Yes - with fT = 150 MHz and VCE(sat) stable up to 125 °C, it supports clean 25 kHz PWM with <100 ns turn-on/off delays. Layout must minimize trace inductance on collector paths to avoid ringing during fast transitions.
Can BCR35PNH6433XTMA1 replace discrete BJT + resistor combinations in existing designs?
Yes - it replaces two BJTs plus four bias resistors (two per channel), reducing component count by six per instance. Existing drive strength and timing behavior are preserved if original R1/R2 values were near 10 kΩ/47 kΩ; no firmware or timing changes needed.
