Product details

Overview

NSVBC847BLT3G from onsemi is an NPN general-purpose bipolar junction transistor in SOT-23 package, rated for 45 V_CEO, 100 mA continuous collector current, and 225 mW power dissipation on FR-5 board. It features h_FE = 200–450 at I_C = 2 mA, V_CE(sat) ≤ 0.25 V at I_C = 10 mA/I_B = 0.5 mA, and is AEC-Q101 qualified for automotive signal switching applications.

For engineers reviewing the NSVBC847BLT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its guaranteed DC current gain range, low saturation voltage under defined drive conditions, thermal performance on standard PCBs, and automotive qualification status - all critical for reliable discrete amplification and switching in space-constrained control circuits.

Technical Context

This device operates as a silicon NPN BJT optimized for linear amplification and saturated switching in low-power analog and digital interface circuits. Its f_T = 100 MHz supports RF-capable small-signal amplification up to VHF band, while C_obo = 4.5 pF enables stable high-frequency biasing.

Designed for operation across −55°C to +150°C junction temperature, it delivers consistent h_FE behavior over temperature (±1.0 mV/°C V_BE tempco) and maintains safe operating area integrity up to 100 V_CE/0.1 A with thermal derating of 1.8 mW/°C above 25°C on FR-5 board.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe DC bias headroom in switching applications.
I_C (continuous)	100 mA - Absolute maximum steady-state collector current; sets upper limit for load-driving capability in relay drivers or LED interfaces.
h_FE	200–450 @ I_C = 2 mA, V_CE = 5 V - Guaranteed DC current gain range ensures predictable base drive requirements in amplifier and switch designs.
V_CE(sat)	≤ 0.25 V @ I_C = 10 mA, I_B = 0.5 mA - Low saturation voltage minimizes conduction loss and self-heating in digital logic-level switching.
f_T	100 MHz - Transition frequency confirms usable bandwidth for small-signal amplification up to ~10 MHz with gain margin.
P_D (FR-5)	225 mW @ T_A = 25°C - Power handling capacity on standard epoxy PCB; requires thermal derating above ambient for sustained operation.
R_JA	556 °C/W - Junction-to-ambient thermal resistance on FR-5 board; determines temperature rise per watt dissipated in layout planning.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847BLT3G	No NSV prefix; not AEC-Q101 qualified; identical electrical specs and SOT-23 package.	Intended for commercial/industrial use only; unsuitable for automotive production programs requiring PPAP documentation.	Select BC847BLT3G only if automotive qualification is not required and cost sensitivity outweighs supply chain traceability needs.
MMBT3904LT1G	Higher V_CEO = 40 V (vs. 45 V), h_FE = 100–300 @ I_C = 10 mA, same SOT-23 footprint but different pinout (E-B-C vs. B-E-C).	Requires PCB layout revision due to reversed emitter/base pin assignment; not drop-in compatible.	Choose MMBT3904LT1G only after verifying pinout compatibility and validating gain performance at target operating point.

Compared with NSVBC847BLT3G, BC847BLT3G offers identical electrical behavior but lacks automotive qualification and traceability, while MMBT3904LT1G demands mechanical redesign due to non-matching pinout - making NSVBC847BLT3G the sole option meeting AEC-Q101, SOT-23 B-E-C pinout, and 45 V/100 mA specification simultaneously.

FAQ

What is the maximum collector-emitter voltage rating for NSVBC847BLT3G?

The NSVBC847BLT3G has a maximum collector-emitter voltage (V_CEO) rating of 45 V under open-base conditions. This value is specified in the Maximum Ratings table of the official onsemi datasheet (Rev. 20, June 2024) and defines the absolute upper limit for DC bias across the collector and emitter terminals before breakdown occurs. Exceeding this voltage risks permanent device damage.

Is NSVBC847BLT3G pin-compatible with BC847BLT3G?

Yes, NSVBC847BLT3G is pin-compatible with BC847BLT3G - both use SOT-23 package with identical pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. The NSV prefix indicates automotive qualification (AEC-Q101, PPAP capable), while BC847BLT3G is the commercial-grade variant. Electrical specifications are identical; only qualification and traceability differ.

What is the guaranteed DC current gain (h_FE) range for NSVBC847BLT3G at I_C = 2 mA?

The NSVBC847BLT3G guarantees h_FE = 200 to 450 when tested at I_C = 2 mA and V_CE = 5 V, per the Electrical Characteristics table in the onsemi datasheet. This range reflects the "B" gain group within the BC847 family and ensures predictable base drive requirements for amplifier and switching designs across manufacturing lots.

Does NSVBC847BLT3G support reflow soldering without moisture preconditioning?

Yes, NSVBC847BLT3G has Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking. No floor-life limitation or pre-reflow bake cycle is required, simplifying assembly logistics and eliminating risk of popcorning during lead-free reflow profiles.

What is the thermal resistance (R_JA) of NSVBC847BLT3G on FR-5 board?

The NSVBC847BLT3G exhibits a junction-to-ambient thermal resistance (R_JA) of 556 °C/W when mounted on a standard FR-5 PCB (1.0 × 0.75 × 0.062 in) at T_A = 25°C. This value, specified in the Thermal Characteristics table, enables accurate junction temperature estimation using ΔT = P_D × R_JA for thermal design validation.
