Product details

Obsolete — sourcing through independent distribution

The BCR135E6433HTMA1 carries an Obsolete product status.

Automotive-grade pre-biased NPN — what the ratings mean

This is an NPN pre-biased transistor in a PG-SOT23 surface-mount package, qualified to AEC-Q101 for automotive applications. The built-in bias resistors — 10 kOhms base (R1) and 47 kOhms emitter-base (R2) — eliminate two external passives from the BOM, saving placement cost and board area in high-volume ECU modules. Collector-emitter breakdown is rated at 50 V, with a maximum collector current of 100 mA and power dissipation of 200 mW. The 150 MHz transition frequency is adequate for switching loads up to the low-MHz range, typical for relay drivers, solenoid pre-drivers, and logic-level interface circuits in 12 V automotive environments.

Package and footprint

Supplied in a PG-SOT23 (TO-236-3, SC-59, SOT-23-3) package, surface-mount only. The three-pin footprint matches standard SOT-23 land patterns. No exposed pad; thermal dissipation relies on the package body and PCB copper.

Frequently asked questions

What is the replacement for BCR135E6433HTMA1?

For a pin-compatible pre-biased NPN in SOT-23 with the same resistor ratio (10 kOhm base / 47 kOhm emitter-base), evaluate Infineon's current BCR135 series variants or a cross from Nexperia (PDTC series) or Rohm (DTC series) — verify AEC-Q101 grade and package compatibility before substituting.

Is BCR135E6433HTMA1 AEC-Q101 qualified?

Yes, it carries AEC-Q101 qualification, making it suitable for automotive applications where the part is still available through surplus or broker channels.

What package is BCR135E6433HTMA1?

PG-SOT23, also described as TO-236-3, SC-59, SOT-23-3. It is a three-lead surface-mount package.

What are the base and emitter-base resistor values?

The base resistor (R1) is 10 kOhms; the emitter-base resistor (R2) is 47 kOhms.
