Diodes Incorporated BC807-16W-7

Overview

BC807-16W-7 from Diodes Incorporated is a 45 V, -500 mA PNP small-signal transistor in SOT323 package, featuring h_FE = 100–250 at I_C = -100 mA, V_CE = -1.0 V, V_CE(sat) = -700 mV at I_C = -500 mA/I_B = -50 mA, and f_T = 100 MHz - used for switching and audio-frequency amplification in space-constrained consumer and industrial PCBs.

For engineers reviewing the BC807-16W-7 datasheet, BC807-16W-7 pinout, BC807-16W-7 application, or BC807-16W-7 equivalent, key selection criteria include guaranteed DC current gain range, low saturation voltage under high-current drive, thermal resistance (R_θJA = 625 °C/W), ESD robustness (HBM = 4 kV), and automotive-grade manufacturing capability (IATF 16949, AEC-Q101 capable).

Technical Context

This PNP bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage. Its complementary NPN counterpart is BC817-16W, enabling matched pair design in push-pull or differential stages. The device operates across -65 °C to +150 °C with guaranteed breakdown ratings: V_CEO = -45 V, V_EBO = -6 V, and I_CES ≤ -100 nA at V_CE = -45 V.

Designed for automatic insertion and reflow-compatible assembly, it uses matte tin-plated leads per MIL-STD-202, Method 208, and meets J-STD-020 moisture sensitivity Level 1. Its SOT323 footprint supports high-density layouts while maintaining thermal performance via optimized pad layout (1 oz copper, single-sided FR4).

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous collector current for BC807-16W-7?

The BC807-16W-7 is rated for -500 mA continuous collector current (I_C) at T_A = +25 °C with proper PCB thermal management. Derating is required above +25 °C per the R_θJA = 625 °C/W specification; at +70 °C ambient, maximum I_C drops to approximately -320 mA to maintain junction temperature below 150 °C.

Is BC807-16W-7 suitable for automotive applications?

Yes - BC807-16W-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 out-of-box, Diodes offers AEC-Q101 qualification upon request for specific lots, making it suitable for automotive body electronics, infotainment, and lighting control modules.

How does the SOT323 package affect thermal performance?

The SOT323 package delivers compact size (2.15 mm × 2.10 mm) but has higher thermal resistance: R_θJA = 625 °C/W on minimum recommended 1 oz copper FR4. To sustain full -500 mA current, keep ambient temperature ≤ +55 °C or enhance copper area and thermal vias - unlike larger SOT-23 variants which achieve ~400 °C/W.

What is the meaning of the "K5A" marking on BC807-16W-7?

"K5A" is the top-side laser marking code: "K5" identifies the BC807-16W device type, and "A" denotes the gain bin (h_FE = 100–250). Date code follows separately (e.g., "N9" = 2026, September) per Diodes' standard marking scheme defined in DS30577.
