Infineon Technologies BC807-40E6359

Overview

BC807-40E6359 from Nexperia is a PNP silicon general-purpose audio-frequency transistor with h_FE = 250–630 (IC = 100 mA, V_CE = 1 V), V_CEO = 45 V, I_C = 500 mA, and V_CE(sat) ≤ 0.7 V at IC = 500 mA/IB = 50 mA. It operates in SOT23 package and serves as a medium-power switching or linear amplification device in low-voltage DC control circuits.

For engineers reviewing the BC807-40E6359 datasheet, BC807-40E6359 pinout, BC807-40E6359 application, or BC807-40E6359 equivalent, key selection criteria include guaranteed high-current gain group (h_FE ≥ 250), low saturation voltage for efficient switching, AEC-Q101 qualification for automotive-grade reliability, and RoHS-compliant lead-free packaging.

Technical Context

This PNP bipolar junction transistor uses epitaxial planar technology to deliver stable DC current gain across temperature (−40 °C to 150 °C) and collector current (10 mA to 500 mA). Its f_T = 200 MHz enables use in AF amplification and moderate-speed switching up to ~10 MHz.

The device features low thermal resistance (R_thJS ≤ 215 K/W) in SOT23, supports pulsed operation up to 1 A peak (I_CM), and maintains V_BE(sat) ≤ 1.2 V under heavy drive-enabling direct interface with microcontroller GPIOs without external base resistors in some configurations.

FAQ

Is BC807-40E6359 pin-compatible with BC807-16 or BC807-25?

Yes-BC807-40E6359 shares identical SOT23 pinout (E-B-C) and mechanical footprint with all BC807 variants. Only the h_FE group differs: BC807-16 (h_FE = 100–160), BC807-25 (160–250), and BC807-40 (250–630). Substitution is electrically valid if circuit gain margin accommodates lower h_FE.

What is the maximum allowable junction temperature and how is it enforced?

The absolute maximum junction temperature is 150 °C. This limit is enforced through thermal derating: total power dissipation must be reduced linearly above 79 °C case temperature (P_tot = 330 mW at T_S ≤ 79 °C, down to 0 mW at 150 °C), per the derating curve in Figure 7 of the datasheet.

Can BC807-40E6359 replace BC808-40 in a 24 V system?

No-BC808-40 has V_CEO = 25 V and is rated for ≤24 V nominal systems with tight transient margins. BC807-40E6359 has V_CEO = 45 V and is safe in the same 24 V environment but not functionally interchangeable due to different breakdown ratings and gain curves; substitution requires validation of worst-case V_CB stress.

Does BC807-40E6359 support pulsed operation beyond its DC current rating?

Yes-it supports peak collector current I_CM = 1000 mA for pulse widths < 300 µs and duty cycle < 2%. This enables short-duration surge handling (e.g., motor startup, relay coil energization) without exceeding thermal limits, provided average power remains within the 330 mW DC rating at the operating case temperature.
