Product details
Overview
BS107PSTOB 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 RDS(ON) at VGS = 2.6V, and 500mW power dissipation-used in low-power switching and signal-level load control in automotive body electronics and industrial sensor interfaces.
For engineers reviewing the BS107PSTOB datasheet, BS107PSTOB pinout, BS107PSTOB application, or BS107PSTOB equivalent, key selection factors include its 200V VDSS, 1.0–3.0V gate threshold, 71°C/W junction-to-leads thermal resistance, and AEC-Q101-qualified automotive-grade compatibility via Q-suffix variants.
Technical Context
This DMOSFET employs a vertical structure optimized for high-voltage blocking with low on-resistance in a through-hole package. Its 200V breakdown voltage and 120mA ID rating target low-current, medium-voltage switching where thermal management is constrained by PCB layout and ambient conditions.
Gate drive is compatible with 2.6V logic-level signals, enabling direct interface with microcontrollers and comparators. Dynamic parameters-including 7ns turn-on delay, 8ns rise time, and 85pF input capacitance-are specified under 25V VDD and 250mA ID, supporting reliable operation in pulse-width modulated loads below 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 200 V - Sustains up to 200V drain-source voltage without breakdown, suitable for 12–48V system rails with margin. |
| RDS(ON) | 15–23 Ω @ VGS=2.6V - Enables ~30mW conduction loss at 120mA, critical for thermally limited PCBs. |
| ID (continuous) | 120 mA - Maximum steady-state load current; derated above 25°C per 200°C/W RθJA. |
| VGS(TH) | 1.0–3.0 V - Ensures reliable turn-on with 3.3V or 5V logic outputs without external level-shifting. |
| PD | 500 mW - Power limit under still-air conditions on minimum pad layout; requires thermal relief for sustained operation. |
| Ciss | 85 pF - Input capacitance affects gate drive strength requirements and switching speed in PWM circuits. |
| tD(ON) | 7 ns - Fast turn-on delay supports high-frequency switching up to ~10MHz in low-duty-cycle applications. |
Pinout & Package
E-Line (TO-92 compatible) molded plastic package with matte tin-plated leads; 0.159g weight; UL 94V-0 flammability rating; flat-face orientation with ejection mark and part marking "BS107" on rounded face.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Receives logic-level voltage to modulate channel conductivity; requires <10nA leakage handling in high-impedance bias networks. |
| D (Drain) | High-side current path | Connected to load supply rail; carries full switched current and must be routed with thermal relief for 500mW dissipation. |
| S (Source) | Reference node / return path | Typically tied to ground or low-side shunt; establishes VGS reference and impacts gate drive loop inverting configuration. |
Key Features
| Feature | Design Value |
|---|---|
| 200V VDSS rating | Supports operation across 24V/36V/48V industrial and automotive battery systems with safety margin. |
| 120mA ID continuous | Matches typical current draw of LED arrays, small solenoids, and sensor biasing circuits. |
| 23Ω RDS(ON) @ 2.6V | Enables direct drive from low-voltage MCUs without gate drivers in space-constrained designs. |
| AEC-Q101 qualified variant available | Q-suffix parts meet automotive change control, PPAP, and IATF 16949 manufacturing requirements. |
| Halogen & antimony free | Complies with green electronics standards (<900ppm Br/Cl, <1000ppm Sb) for RoHS 3 and export compliance. |
Applications
| Automotive Interior Lighting | Industrial Sensor Biasing |
|---|---|
Use Scenario: Switching 12V LED strips in door modules and map lights with PWM dimming. IC Role / Device Role: Low-side load switch controlling current path to LED anode. Use Value: 200V rating prevents failure during load dump transients; 120mA rating matches typical 3–5 LED strings. | Use Scenario: Providing stable bias current to RTD or thermistor bridges in factory-floor temperature sensors. IC Role / Device Role: Precision current source switch enabling ratiometric measurement. Use Value: 1.0–3.0V VGS(TH) allows clean turn-on with 3.3V DAC outputs; low IDSS ensures minimal offset error. |
| Low-Power Relay Drivers | Smart Meter Load Control |
Use Scenario: Driving coil of miniature 5V/12V relays in HVAC control panels. IC Role / Device Role: Solid-state replacement for mechanical relay contacts in low-energy switching. Use Value: 7ns tD(ON) and 8ns tR support fast relay actuation timing; 500mW PD accommodates brief inrush currents. | Use Scenario: Controlling auxiliary loads (e.g., tamper alarms, status LEDs) in Class 0.5S electricity meters. IC Role / Device Role: Isolated load switch managed by metrology MCU with watchdog supervision. Use Value: RθJL = 71°C/W enables predictable thermal behavior on meter PCBs with limited copper area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN2110A | VDSS = 60V, RDS(ON) = 10Ω @ 5V, TO-92 package | Limited to ≤24V systems; lower on-resistance but insufficient for 48V load-dump immunity | Select only for cost-sensitive 5–12V non-automotive applications where voltage margin is not required. |
| DMN2004LK-7 | VDSS = 20V, RDS(ON) = 3.5Ω @ 4.5V, SOT-23 package | Surface-mount, higher current capability, but incompatible with 200V transient environments | Prefer for space-constrained PCBs operating strictly below 12V with high efficiency demands. |
Compared with ZVN2110A and DMN2004LK-7, BS107PSTOB uniquely balances 200V robustness, through-hole reliability, and logic-level gate drive-making it optimal for automotive-adjacent and industrial 24–48V systems where transient immunity and serviceability matter.

FAQ
What is the maximum safe operating voltage for BS107PSTOB in automotive environments?
The BS107PSTOB has a 200V VDSS rating and is designed to withstand automotive load-dump transients up to 130V (per AEC-Q101 stress testing). For long-term reliability in 12V/24V systems, it is recommended to maintain VDS ≤ 100V during normal operation, reserving margin for ISO 7637-2 Pulse 5a events.
Can BS107PSTOB be driven directly by a 3.3V microcontroller GPIO?
Yes-its 1.0–3.0V gate threshold voltage and 23Ω RDS(ON) at VGS = 2.6V ensure full enhancement with standard 3.3V logic outputs. No external gate driver is needed for 120mA loads, though series gate resistance (≥100Ω) is advised to suppress ringing in high-di/dt layouts.
How does the E-Line package compare thermally to standard TO-92?
The E-Line package shares TO-92 pinout and footprint but features optimized leadframe geometry yielding 71°C/W RθJL-significantly better than typical TO-92's >150°C/W. This improves power handling in confined spaces, especially when soldered to internal PCB copper layers for enhanced heat spreading.
Is BS107PSTOB suitable for linear (analog) operation?
No-it is characterized and qualified for switching operation only. The device lacks guaranteed Safe Operating Area (SOA) curves for linear mode, and its 500mW power limit assumes pulsed or intermittent duty cycles. Linear use risks thermal runaway due to positive temperature coefficient of RDS(ON) and absence of SOA validation.
