Product details

Overview

BS107P from Diodes Incorporated is a 200V N-channel enhancement-mode vertical DMOSFET in E-Line (TO-92 compatible) package, rated for 120mA continuous drain current, 23Ω R_DS(ON) at V_GS = 2.6V, and 500mW power dissipation-used in low-power switching and load control circuits such as LED drivers and sensor interface stages.

For engineers reviewing the BS107P datasheet, BS107P pinout, BS107P application, or BS107P equivalent, key selection criteria include its 200V V_DSS, low-threshold gate drive compatibility (V_GS(TH) = 1.0–3.0V), thermal resistance (R_θJA = 200°C/W), and AEC-Q101-qualified reliability for automotive-grade variants.

Technical Context

This DMOSFET employs a vertical conduction structure optimized for high-voltage blocking with low on-resistance in a through-hole TO-92-compatible outline. Its 200V breakdown voltage and 120mA ID rating target space-constrained, low-current switching where gate drive simplicity and thermal stability are critical.

The device operates with a gate threshold voltage range of 1.0–3.0V and delivers 15–23Ω R_DS(ON) at 2.6V gate bias-enabling direct interfacing with 3.3V logic or microcontroller GPIOs without level-shifting. Dynamic parameters (e.g., t_D(ON) = 7ns, C_iss = 85pF) confirm suitability for medium-speed switching up to ~1MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	200 V - Sustains 200V drain-source blocking without avalanche conduction under normal operation.
R_DS(ON)	15–23 Ω @ V_GS = 2.6V - Enables efficient low-current switching with minimal I²R loss at logic-level gate drive.
I_D (continuous)	120 mA - Supports steady-state loads such as indicator LEDs, small solenoids, or signal-path switches.
P_D	500 mW - Limits maximum power handling on standard FR-4 PCB with minimum pad layout and still-air cooling.
V_GS(TH)	1.0–3.0 V - Ensures reliable turn-on from 3.3V or 5V digital outputs without external gate drivers.
R_θJA	200 °C/W - Defines junction-to-ambient thermal rise per watt; requires derating above +25°C ambient.
C_iss	85 pF - Input capacitance impacts gate drive current requirements and switching speed in PWM applications.

Applications

LED Indicator Control

Low-Power Sensor Interface

Use Scenario: Driving discrete status LEDs in automotive instrument clusters or industrial HMI panels.

IC Role / Device Role: Low-side switch controlling LED anode-to-VCC current path.

Use Value: 120mA rating supports multi-LED strings; 23Ω R_DS(ON) limits voltage drop to <3V at 120mA, preserving brightness.

Use Scenario: Enabling/disabling analog sensor biasing (e.g., thermistor or photodiode networks) during sleep cycles.

IC Role / Device Role: Power-gating switch isolating sensor supply to reduce system quiescent current.

Use Value: 30nA I_DSS ensures sub-µA leakage during off-state, extending battery life in portable monitoring devices.

Microcontroller Peripheral Driver

Small-Signal Load Switch

Use Scenario: Direct GPIO-driven actuation of piezoelectric buzzers or miniature relays in embedded control modules.

IC Role / Device Role: Voltage-controlled current switch interfacing between MCU output and inductive load.

Use Value: 2A pulsed drain rating accommodates relay coil inrush; 7ns t_D(ON) enables precise timing in feedback-controlled tone generation.

Use Scenario: Isolating auxiliary circuitry (e.g., display backlight or USB port power) in consumer electronics.

IC Role / Device Role: High-side or low-side power switch managing domain-specific power domains.

Use Value: 500mW P_D and 200°C/W R_θJA allow safe operation at 120mA in compact PCB layouts without heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-current MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVN2110A	V_DSS = 60V, R_DS(ON) = 10Ω @ V_GS = 5V, TO-92 package	Lower voltage rating limits use to ≤24V systems; lower R_DS(ON) reduces conduction loss at higher gate drive.	Select when operating below 60V and prioritizing on-resistance over voltage margin.
DMN2004LK-7	V_DSS = 20V, R_DS(ON) = 3.5Ω @ V_GS = 4.5V, SOT-23 package	SMT-only, lower voltage, significantly lower R_DS(ON); unsuitable for >20V or through-hole assembly.	Choose for high-density PCBs requiring surface-mount integration and sub-20V operation.

Compared with ZVN2110A and DMN2004LK-7, BS107P uniquely balances 200V blocking capability with logic-level gate drive in a through-hole package-making it irreplaceable in cost-sensitive, medium-voltage, low-current applications requiring manual assembly or legacy board compatibility.

FAQ

What is the maximum gate-source voltage for BS107P?

The absolute maximum gate-source voltage (V_GS) is ±20V. Exceeding this rating risks permanent gate oxide damage. For reliable operation, gate drive should be limited to ≤±15V, with typical use at 2.6V–5V to achieve specified R_DS(ON) while maintaining margin against transient overshoot.

Can BS107P be used in automotive applications?

Yes-the BS107P is qualified to JEDEC standards referenced in AEC-Q101 and manufactured in IATF 16949-certified facilities. While the standard BS107P is not automotive-grade marked, its Q-suffix automotive variants (e.g., BS107Q) are available and PPAP-capable for qualified automotive designs.

What is the thermal resistance from junction to leads (R_θJL) for BS107P?

R_θJL is 71°C/W, measured from junction to solder-point at the seating plane (2.5mm from package bottom along the drain lead). This value supports more accurate thermal modeling than R_θJA when the device is soldered to a copper pour or heatsinked lead.

How does BS107P's R_DS(ON) vary with temperature?

R_DS(ON) increases with junction temperature-typical positive temperature coefficient behavior. At 100°C, R_DS(ON) is approximately 1.5× the 25°C value (i.e., ~22–35Ω at V_GS = 2.6V), requiring thermal derating in sustained high-temperature operation.
