onsemi SBC807-16LT3

Overview

SBC807-16LT3 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-5 board at 25°C. It delivers h_FE = 100–250 at I_C = −100 mA/V_CE = −1.0 V and supports low-saturation switching in discrete bias networks and level-shifting circuits.

For engineers reviewing the SBC807-16LT3 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed DC current gain range, V_CE(sat) ≤ −0.7 V at I_C/I_B = 10, thermal resistance of 556°C/W, and Pb-free SOT-23 tape-and-reel packaging (10,000 units).

Technical Context

The SBC807-16LT3 operates as a medium-current PNP bipolar junction transistor optimized for linear amplification and saturated switching. Its base-emitter junction withstands −5.0 V reverse voltage, collector-base up to −50 V, and it maintains stable h_FE across −55°C to +150°C junction temperature range.

Designed for use in low-voltage analog signal conditioning and digital logic interface circuits, the device exhibits f_T = 100 MHz at I_C = −10 mA/V_CE = −5.0 V and C_obo = 10 pF at V_CB = −10 V, enabling reliable performance in audio preamp stages and microcontroller GPIO driver stages.

FAQ

What is the maximum collector current rating for the SBC807-16LT3?

The SBC807-16LT3 has a maximum continuous collector current rating of −500 mA at T_A = 25°C. This value decreases with rising ambient temperature per the derating factor of 1.8 mW/°C for FR-5 board mounting. Exceeding this limit risks thermal runaway and permanent degradation of h_FE and V_CE(sat) in the SBC807-16LT3.

Does the SBC807-16LT3 support lead-free soldering processes?

Yes, the SBC807-16LT3 is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles with peak temperatures up to 260°C. Its SOT-23 package meets JEDEC J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to assembly. This applies specifically to the SBC807-16LT3 variant as shipped in 10,000-unit tape-and-reel format.

What is the guaranteed DC current gain (h_FE) range for the SBC807-16LT3?

The SBC807-16LT3 guarantees h_FE between 100 and 250 when tested at I_C = −100 mA and V_CE = −1.0 V. This binning ensures predictable biasing in amplifier and switch designs without post-manufacture sorting. The SBC807-16LT3 does not guarantee h_FE at higher currents-performance at I_C = −500 mA is characterized but not binned.

Can the SBC807-16LT3 be used as a direct replacement for BC807-16LT1?

Yes, the SBC807-16LT3 is functionally identical to BC807-16LT1 in electrical parameters, thermal characteristics, and pinout. The only differences are packaging quantity (10,000 vs. 3,000 per reel) and absence of alphanumeric marking (5A1) on the SBC807-16LT3 die. No PCB layout or schematic changes are required when substituting SBC807-16LT3 for BC807-16LT1.

What is the thermal resistance (R_JA) of the SBC807-16LT3 on a standard FR-5 PCB?

The SBC807-16LT3 has a junction-to-ambient thermal resistance of 556°C/W when mounted on a 1.0 × 0.75 × 0.062 inch FR-5 board at T_A = 25°C. This value assumes no copper pour or thermal vias. For designs dissipating >100 mW, thermal simulation or empirical measurement using the SBC807-16LT3 is recommended to validate safe operating area.
