Diodes Incorporated BC807-16-7-F

Overview

BC807-16-7-F from Diodes Incorporated is a 45 V, -500 mA PNP small-signal transistor in SOT23 package, featuring h_FE = 100–250 at I_C = -100 mA, V_CE(sat) = -0.7 V at I_C = -500 mA/I_B = -50 mA, and f_T = 100 MHz. It serves as a general-purpose switching and audio-frequency amplifier device in compact power management and signal conditioning circuits.

For engineers reviewing the BC807-16-7-F datasheet, BC807-16-7-F pinout, BC807-16-7-F application, or BC807-16-7-F equivalent, key selection criteria include guaranteed DC current gain across operating current range, low saturation voltage under high drive conditions, thermal performance on standard FR4 PCBs, and automotive-grade alternatives for mission-critical designs.

Technical Context

This PNP bipolar junction transistor uses epitaxial planar die construction to ensure stable gain and low leakage across -55°C to +150°C ambient operation. Its complementary NPN counterpart is BC817-16, enabling matched pair design in push-pull stages and differential amplifiers.

The device operates with V_CEO = -45 V, V_CB0 = -50 V, and V_EB0 = -5.0 V, supporting robust reverse-bias margin in low-voltage rail-switching applications. Thermal resistance R_θJA is 403°C/W on minimum pad layout and 357°C/W on 15 mm × 15 mm FR4, defining practical power handling limits in space-constrained layouts.

FAQ

What is the maximum operating temperature for BC807-16-7-F?

The BC807-16-7-F has an operating junction temperature range of -55°C to +150°C, with storage temperature matching that span. Its thermal resistance R_θJA = 403°C/W on standard FR4 means at 310 mW dissipation and 25°C ambient, junction temperature reaches approximately 153°C-thus derating is required above 25°C ambient to stay within 150°C limit.

Is BC807-16-7-F pin-compatible with BC807-25-7-F or BC807-40-7-F?

Yes-BC807-16-7-F, BC807-25-7-F, and BC807-40-7-F share identical SOT23 package, pinout, and absolute maximum ratings; only DC current gain (h_FE) differs (100–250 vs. 160–400 vs. 250–600). Substitution is electrically valid if the circuit's gain tolerance accommodates the selected grade.

Does BC807-16-7-F support pulsed operation beyond its continuous current rating?

Yes-its peak collector current I_CM is rated at -1.0 A, and pulse testing conditions specify ≤300 µs pulse width with ≤2% duty cycle. This enables short-duration surge handling in motor startup or relay driving, provided average power remains within 310 mW and thermal limits are observed.

How does the "K5A" marking on BC807-16-7-F relate to its specifications?

"K5A" is the top-side package marking code identifying the BC807-16 variant per Diodes' ordering matrix. It does not encode electrical parameters but confirms the part's gain bin (h_FE = 100–250), package type (SOT23), and manufacturing lot traceability-distinct from K5B (BC807-25) and K5C (BC807-40).
