Product details

Overview

SBC807-16LT1 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 switching and linear amplification in low-voltage bias networks.

For engineers reviewing the SBC807-16LT1 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 (FR-5), and Pb-free SOT-23 compatibility with automated surface-mount assembly.

Technical Context

The SBC807-16LT1 operates as a medium-current PNP bipolar junction transistor optimized for general-purpose switching and analog amplification. Its design targets stable h_FE performance across −55°C to +150°C junction temperature range and supports reliable operation under continuous collector currents up to −500 mA with V_CE ≤ −45 V.

It features low saturation voltage (V_CE(sat) ≤ −0.7 V at I_C = −500 mA, I_B = −50 mA) and base-emitter on voltage of −1.2 V, enabling efficient drive in low-side load control and level-shifting circuits where emitter-follower or common-emitter configurations are used.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum allowable collector-to-emitter voltage before breakdown in open-base condition
I_C	−500 mA - Continuous collector current rating defining safe DC conduction capability
h_FE	100–250 - DC current gain range at I_C = −100 mA, V_CE = −1.0 V, critical for bias stability in amplifier stages
V_CE(sat)	≤ −0.7 V - Saturation voltage at I_C/I_B = 10, directly impacts power loss and switching efficiency
R_JA	556°C/W - Junction-to-ambient thermal resistance on FR-5 board, determines max ambient temperature for full-power operation
f_T	100 MHz - Current-gain bandwidth product, sets upper limit for small-signal amplification frequency

Pinout & Package

SOT-23 (Case 318, Style 6) surface-mount plastic package with 3 terminals; dimensions: 2.90 mm × 1.30 mm × 0.95 mm (L × W × H); RoHS-compliant and Pb-free options available.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-16LT1G	Pb-free variant of same die and SOT-23 package; identical electrical specs and thermal ratings	No functional difference; selected when RoHS compliance or lead-free assembly is mandatory	Direct replacement for SBC807-16LT1 where Pb-free process is required; no layout or schematic change needed
MMBT807	Same h_FE range and V_CEO, but rated for 350 mW PD on FR-5 board and has R_JA = 357°C/W	Better thermal performance allows higher ambient operation or longer duty cycles at full current	Preferred when thermal headroom is constrained; verify PCB copper area and airflow match MMBT807's improved dissipation profile

Compared with BC807-16LT1G, the SBC807-16LT1 offers identical functionality but lacks Pb-free certification; versus MMBT807, it trades 30% lower power dissipation for broader legacy supply chain availability and tighter cost control in non-thermal-critical designs.

FAQ

What is the maximum continuous collector current rating for the SBC807-16LT1?

The SBC807-16LT1 is rated for −500 mA continuous collector current (I_C) at T_A = 25°C on FR-5 board. This rating assumes proper PCB thermal relief and derates linearly by 1.8 mW/°C above 25°C ambient. Exceeding this current without adequate heatsinking risks thermal runaway and permanent device failure. The SBC807-16LT1 must be operated within its Safe Operating Area (SOA) limits defined in the official onsemi datasheet.

Does the SBC807-16LT1 have a guaranteed DC current gain range?

Yes, the SBC807-16LT1 guarantees h_FE = 100–250 at I_C = −100 mA and V_CE = −1.0 V, per the onsemi BC807−16LT1/D datasheet. This binning ensures predictable biasing in amplifier and switching circuits without requiring individual unit characterization. The SBC807-16LT1 maintains this gain range across its full operating temperature span of −55°C to +150°C.

What is the pin configuration of the SBC807-16LT1 in the SOT-23 package?

The SBC807-16LT1 uses standard SOT-23 pinout: Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector - confirmed in the "PACKAGE DIMENSIONS" section of the onsemi BC807−16LT1/D datasheet (Style 6). This configuration is consistent across all BC807 variants and matches JEDEC TO-236 outline. Incorrect orientation during placement will result in circuit malfunction or device damage. The SBC807-16LT1 marking "5A1" appears adjacent to Pin 1.

Is the SBC807-16LT1 RoHS compliant?

The SBC807-16LT1 is not RoHS compliant as shipped; it is the standard leaded version. For RoHS-compliant alternatives, select the SBC807-16LT1G or BC807-16LT1G variants, which use Pb-free terminations and meet Directive 2011/65/EU. The SBC807-16LT1 datasheet explicitly identifies "G" suffix parts as Pb-free. Always verify compliance status via onsemi's official product change notices before final BOM release.

What is the thermal resistance of the SBC807-16LT1 on FR-5 board?

The SBC807-16LT1 has a junction-to-ambient thermal resistance (R_JA) of 556°C/W when mounted on a standard FR-5 board at 25°C ambient, per the "THERMAL CHARACTERISTICS" table in the onsemi BC807−16LT1/D datasheet. This value assumes minimal copper area; adding thermal vias and copper pour reduces effective R_JA. The SBC807-16LT1 must be thermally managed to keep T_J ≤ +150°C under worst-case load conditions.
