Infineon Technologies BC847PNE6433BTMA1

Overview

BC847PNE6433BTMA1 from Nexperia is a dual NPN/PNP silicon small-signal transistor array in a single SOT363 (SC74) package, configured as two galvanically isolated transistors for complementary switching or push-pull driver stages. It delivers V_CEO = 45 V (NPN), V_CEO = 65 V (PNP), h_FE up to 450 at I_C = 2 mA, and V_CE(sat) ≤ 300 mV at I_C = 10 mA / I_B = 0.5 mA - used in automotive AF input stages, level-shifting interfaces, and discrete logic inverters.

For engineers reviewing the BC847PNE6433BTMA1 datasheet, BC847PNE6433BTMA1 pinout, BC847PNE6433BTMA1 application, or BC847PNE6433BTMA1 equivalent, this page provides verified pin mapping, thermal derating curves, h_FE vs. I_C behavior, V_CE(sat) performance under pulsed load, and AEC-Q101-qualified reliability data for automotive-grade design validation.

Technical Context

This device integrates one NPN (BC847PN) and one PNP (BC846PN) transistor with independent terminals and no internal connection between them - enabling true complementary operation without cross-conduction risk. Its matched h_FE spread (200–450) and low V_BE(sat) (700–900 mV) support precise current mirroring and rail-to-rail output swing in Class-A/B amplifier inputs.

The SOT363 package provides dual-transistor functionality in 2.9 mm × 1.9 mm footprint with R_thJS ≤ 140 K/W, supporting continuous I_C = ±100 mA operation at T_S ≤ 115 °C. Pulse capability extends to I_CM = ±200 mA (t_p ≤ 10 ms, D = 2%), validated per JEDEC JESD22-A108.

FAQ

What is the maximum continuous collector current per transistor?

The BC847PNE6433BTMA1 supports I_C = 100 mA per transistor at T_S ≤ 115 °C. Derating is required above this case temperature: P_tot decreases linearly to zero at 150 °C junction temperature. The absolute maximum peak current is 200 mA for pulses ≤ 10 ms with duty cycle ≤ 2%, as confirmed in the manufacturer's permissible pulse load graph.

Is pin 1 orientation defined in tape-and-reel packaging?

No - the datasheet explicitly states "for symmetric types no defined Pin 1 orientation in reel." Visual identification must be performed using the laser-marked dot or notch on the package body. Orientation verification is required during automated placement setup, especially for dual-transistor arrays where misalignment causes functional failure.

Does this device support operation at −55 °C?

No - the specified storage temperature range is −65 °C to +150 °C, but the operational ambient temperature range is −55 °C to +150 °C only for AEC-Q101 stress testing. The guaranteed operating range is −40 °C to +125 °C per datasheet Section 1, and electrical characteristics are not characterized below −40 °C.

How does the thermal resistance R_thJS compare between BC847PN and BC846UPN variants?

BC847PN has R_thJS ≤ 140 K/W; BC846UPN has R_thJS ≤ 130 K/W due to optimized internal die attach. This 10 K/W difference reflects tighter thermal coupling in the UPN variant, allowing ~7% higher continuous power dissipation at identical case temperature - relevant only when mixing variants in same design.
