onsemi SBC807-16LT3G

Overview

SBC807-16LT3G from onsemi is a PNP silicon general-purpose transistor in SOT-23 package, rated for −45 V V_CEO, −500 mA I_C, and 225 mW power dissipation on FR-4 board; it delivers h_FE = 100–250 at I_C = −100 mA, V_CE = −1.0 V, and is widely used in low-voltage switching and signal amplification circuits in automotive body control modules.

For engineers reviewing the SBC807-16LT3G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed AEC-Q101 qualification, Pb-free/RoHS-compliant packaging, verified DC current gain range, saturation voltage under high-current drive, and thermal derating behavior on standard PCB substrates.

Technical Context

This device operates as a medium-current PNP bipolar junction transistor optimized for linear amplification and saturated switching. Its electrical behavior is defined by V_CEO = −45 V, V_CE(sat) ≤ −0.7 V at I_C = −500 mA/I_B = −50 mA, and f_T = 100 MHz at I_C = −10 mA/V_CE = −5 V, supporting stable operation across −55°C to +150°C junction temperature.

The SBC807-16LT3G shares the BC807 family's SOT-23 footprint and thermal characteristics but is distinguished by its specific h_FE bin (100–250), tighter V_BE(on) ≤ −1.2 V specification, and AEC-Q101 qualification-making it suitable for automotive-grade load switching where reliability under thermal stress and ESD immunity are critical.

FAQ

What is the maximum continuous collector current rating for SBC807-16LT3G?

The SBC807-16LT3G has a maximum continuous collector current (I_C) rating of −500 mA dc at T_A = 25°C. This rating assumes proper PCB thermal management-derating applies above 25°C at 1.8 mW/°C on FR-4 board. Exceeding this current without adequate heatsinking risks thermal runaway and permanent device failure. Always verify actual board-level thermal performance using the published R_JA = 436 °C/W value in your layout.

Is SBC807-16LT3G qualified for automotive applications?

Yes, SBC807-16LT3G is AEC-Q101 qualified and PPAP capable, as confirmed in the official onsemi datasheet (Rev. 17, March 2023). The "S" prefix denotes automotive-grade screening, including stress testing for temperature cycling, humidity, and mechanical shock. This makes SBC807-16LT3G suitable for use in non-safety-critical automotive subsystems such as interior lighting, HVAC controls, and body electronics where long-term reliability under harsh conditions is required.

What is the DC current gain (h_FE) range for SBC807-16LT3G?

The SBC807-16LT3G exhibits a DC current gain (h_FE) range of 100 to 250 when tested at I_C = −100 mA and V_CE = −1.0 V. This binning is consistent across the BC807-16 variant and is guaranteed per datasheet specifications. For design purposes, h_FE(min) = 100 should be used to size base drive resistors, ensuring saturation under worst-case conditions across temperature and process variation.

Does SBC807-16LT3G have a specified current-gain bandwidth product (f_T)?

Yes, the SBC807-16LT3G has a minimum current-gain bandwidth product (f_T) of 100 MHz, measured at I_C = −10 mA, V_CE = −5.0 V, and f = 100 MHz. This parameter confirms suitability for low-frequency RF buffering, audio pre-amplification, and fast-switching digital interface applications-but not for RF power amplification or GHz-range signal processing. Actual f_T may vary with bias point and temperature.

What is the pin configuration of SBC807-16LT3G in the SOT-23 package?

SBC807-16LT3G uses the standard SOT-23 (Case 318) pinout: Pin 1 is Collector, Pin 2 is Base, and Pin 3 is Emitter-viewed from the top with marking dot at top-left corner. This matches JEDEC MO-178 and is identical to BC807-16LT1G and other BC807 variants. Correct orientation is critical: reverse mounting causes immediate circuit malfunction or device damage due to polarity inversion in PNP operation.
