Product details

Overview

BSR16/DG/B4VL from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT-23 package, V_CEO = –60 V, I_C = –800 mA, h_FE = 100–300 at I_C = –150 mA, f_T = 100 MHz, used in low-power switching and linear amplification circuits in consumer power management modules.

For engineers reviewing the BSR16/DG/B4VL datasheet, BSR16/DG/B4VL pinout, BSR16/DG/B4VL application, or BSR16/DG/B4VL equivalent, key selection criteria include DC current gain consistency across temperature, safe operating area under pulsed load conditions, and SOT-23 thermal resistance performance in space-constrained PCB layouts.

Technical Context

This PNP transistor operates with emitter-grounded configuration and supports continuous collector current up to 800 mA at T_amb = 25 °C. Its DC current gain (h_FE) is specified between 100 and 300 at I_C = –150 mA and V_CE = –2 V, with transition frequency f_T of 100 MHz confirming suitability for audio-frequency amplification and moderate-speed switching.

The device features a maximum collector-emitter breakdown voltage V_CEO of –60 V and a saturation voltage V_CE(sat) of –0.15 V at I_C = –500 mA and I_B = –50 mA, enabling efficient operation in low-dropout switch-mode control paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–60 V: Maximum reverse-biased collector-emitter voltage before avalanche breakdown; defines safe operating range in high-side switch configurations.
I_C (max)	–800 mA: Continuous DC collector current rating at 25 °C ambient; sets upper limit for steady-state load drive capability.
h_FE	100–300 @ I_C = –150 mA: DC current gain spread indicating predictable base drive requirements for consistent switching thresholds.
f_T	100 MHz: Transition frequency confirming usable bandwidth for audio preamplifier stages and PWM signal buffering up to ~10 MHz.
V_CE(sat)	–0.15 V @ I_C = –500 mA, I_B = –50 mA: Low saturation voltage minimizes conduction loss in active-low logic-level switching applications.
P_tot	250 mW @ T_amb = 25 °C: Total power dissipation limit defining thermal derating curve for PCB trace copper and ambient airflow constraints.

Pinout & Package

SOT-23 plastic surface-mount package with standard 3-pin layout (Emitter, Base, Collector), JEDEC TO-236AB compliant, footprint compatible with automated pick-and-place equipment and reflow soldering profiles per IPC-J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-impedance return path; determines polarity of bias network and current direction in common-emitter stage.
2 (Base)	Control input	Receives forward-biased current to enable conduction; requires series resistor to limit I_B and ensure h_FE-based I_C scaling.
3 (Collector)	Output current source	Supplies load current when saturated; connected to positive rail in high-side switch topology or to load in common-emitter amplifier.

Key Features

Feature	Design Value
High h_FE consistency	100–300 range at standardized test conditions enables stable base resistor selection across production lots.
Low V_CE(sat)	–0.15 V at I_C = –500 mA reduces power loss by >30% versus comparable PNP transistors with V_CE(sat) > –0.22 V.
100 MHz f_T	Supports clean signal amplification up to 10 MHz without phase distortion, suitable for PWM gate drive buffering.
SOT-23 thermal resistance	R_θJA = 375 K/W allows 150 mW dissipation at 50 °C ambient without heatsink in standard FR-4 layout.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching and amplification applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40/DG/B4VL	Higher h_FE (250–630), same V_CEO and package; lower f_T (80 MHz).	Better for low-base-drive precision current sources; less suitable for >5 MHz signal buffering.	Select when tighter h_FE tolerance is required and bandwidth demand is ≤5 MHz.
MMBT3906LT1G	Lower I_C (–200 mA), same V_CEO, smaller h_FE range (100–300), higher R_θJA (400 K/W).	Only suitable for sub-200 mA loads; limited thermal headroom in compact enclosures.	Choose only for cost-sensitive, low-current signal inversion where 800 mA capability is unnecessary.

Compared with BC807-40/DG/B4VL and MMBT3906LT1G, BSR16/DG/B4VL offers optimal balance of current drive, gain consistency, and RF performance in SOT-23 - making it preferred for 500–800 mA switching with minimal base drive overhead and stable AC response.

FAQ

What is the maximum allowable base current for reliable operation?

The absolute maximum base current is –200 mA, but design practice limits I_B to ≤–50 mA for continuous operation to avoid localized heating and h_FE degradation. At I_C = –500 mA, a typical design uses I_B = –5 mA (h_FE ≈ 100), ensuring saturation with margin across temperature.

Can BSR16/DG/B4VL be used in linear regulator pass transistor applications?

No - its P_tot = 250 mW and R_θJA = 375 K/W limit safe linear operation to ≤150 mW dissipation. For pass transistor use, thermal derating exceeds practical voltage drop × current combinations at ambient >40 °C without forced cooling.

Is this device qualified for automotive applications?

BSR16/DG/B4VL is not AEC-Q101 qualified. It meets industrial-grade reliability standards (JESD22-A108) but lacks the extended temperature testing, failure analysis, and traceability required for automotive ECUs or ADAS subsystems.

Does the SOT-23 package support hand-soldering repair?

Yes - the SOT-23 footprint is compatible with fine-tip soldering irons (≤0.5 mm tip) and hot-air rework stations (350–380 °C nozzle temp). Proper pad cleaning and flux application are essential to avoid tombstoning or solder bridging due to tight 0.95 mm pin pitch.
