Product details
Overview
BS107PSTZ 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, LED biasing, and signal-level load control in industrial sensor interfaces and automotive body electronics.
For engineers reviewing the BS107PSTZ datasheet, BS107PSTZ pinout, BS107PSTZ application, or BS107PSTZ equivalent, key selection criteria include its 200V VDSS, low gate threshold (1.0–3.0V), TO-92-compatible E-Line joggled lead configuration, JEDEC-qualified reliability, and suitability for space-constrained 12V/24V DC control circuits requiring <200mW thermal budget.
Technical Context
This DMOSFET employs vertical channel architecture enabling high breakdown voltage with low on-resistance in a through-hole plastic package. Its 1.0–3.0V gate threshold supports direct drive from microcontroller GPIOs, while 200V VDSS and 30nA IDSS at 130V ensure robust off-state blocking in inductive load switching.
Thermal design is constrained by RθJA = 200°C/W (on FR-4 with 12mm leads) and RθJL = 71°C/W to solder point, limiting steady-state operation to ≤125°C junction temperature under 500mW dissipation-making it suitable for non-heatsinked, intermittent-duty applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 200 V - Withstands up to 200V drain-source voltage before avalanche conduction, enabling use in 12V/24V systems with voltage transients. |
| RDS(ON) | 15–23 Ω @ VGS=2.6V - Low on-resistance allows efficient switching of ≤120mA loads without external gate drivers. |
| ID | 120 mA continuous - Maximum steady-state current rating; pulsed capability extends to 2A for short durations. |
| PD | 500 mW - Power limit under standard mounting; requires PCB pad layout per datasheet Note 5 for thermal compliance. |
| VGS(TH) | 1.0–3.0 V - Gate turn-on threshold compatible with 3.3V and 5V logic outputs, eliminating need for level-shifting. |
| Ciss | 85 pF - Input capacitance determines gate drive energy and switching speed in low-frequency (<100kHz) applications. |
| RθJA | 200 °C/W - Junction-to-ambient thermal resistance defines maximum ambient temperature for safe operation at full power. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control electrode; accepts 0–20V gate-source voltage; threshold activation begins at 1.0V. |

Key Features
| Feature | Design Value |

| E-Line (TO-92 Compatible) Package | Enables drop-in replacement in legacy through-hole designs while supporting automated tape-and-reel assembly. |
Applications
| LED Driver Circuit | Low-Voltage Sensor Bias |
|---|---|
Use Scenario: Constant-current switching for indicator LEDs in automotive dashboards and industrial HMI panels. IC Role / Device Role / Timing Role: Low-side switch controlling LED anode current path with PWM dimming capability. Use Value: 23Ω RDS(ON) limits voltage drop to <2.8V at 120mA, preserving headroom for 12V supply rails. |
Use Scenario: Providing stable bias current to analog sensors (e.g., thermistors, photodiodes) in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Precision current source enabled by low gate leakage (<10nA) and stable VGS(TH). Use Value: 30nA IDSS at 130V ensures minimal off-state leakage, critical for µA-level sensor bias accuracy. |
| Small Relay Driver | Microcontroller GPIO Expander |
Use Scenario: Driving 5–12V coil relays in programmable logic controllers and home automation hubs. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relay contacts in low-duty-cycle control paths. Use Value: 2A pulsed drain rating accommodates relay inrush currents; 200V VDSS suppresses coil flyback spikes. |
Use Scenario: Extending MCU I/O count by switching discrete loads (e.g., status indicators, buzzer drivers) from limited GPIO pins. IC Role / Device Role / Timing Role: Level-translating buffer for 3.3V/5V GPIOs controlling higher-voltage peripherals. Use Value: 1.0–3.0V VGS(TH) ensures full enhancement with standard logic outputs, eliminating external driver ICs. |
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 | RDS(ON) = 10Ω @ VGS=4.5V; VDSS = 60V; TO-92 package | Limited to ≤60V systems; lower on-resistance improves efficiency but reduces transient margin | Select when operating below 48V and prioritizing conduction loss over voltage headroom |
| BS170 | RDS(ON) = 5Ω @ VGS=10V; VDSS = 60V; same E-Line footprint | Requires higher gate drive (≥5V); unsuitable for 200V transient environments | Choose only for cost-sensitive 5V logic-driven applications where voltage stress is strictly controlled |
Compared with ZVN2110A and BS170, BS107PSTZ uniquely balances 200V ruggedness with logic-level gate drive and JEDEC reliability-making it the only option qualified for automotive body electronics where both voltage margin and GPIO compatibility are mandatory.

FAQ
Is BS107PSTZ suitable for automotive applications?
Yes-BS107PSTZ is JEDEC-qualified per AEC-Q101 references and manufactured in IATF 16949-certified facilities. While the standard part lacks formal PPAP documentation, its construction, testing, and thermal specs align with automotive body electronics requirements such as LED lighting and sensor biasing. For full AEC-Q101 certification, specify the Q-suffix variant.
What is the difference between BS107P and BS107PSTZ?
BS107P uses straight leads and ships in loose boxes (4,000 units), while BS107PSTZ features joggled leads optimized for tape-and-reel automated assembly and ships in ammo boxes (2,000 units). Both share identical electrical specifications, package outline (E-Line), and marking code (BS107).
Can BS107PSTZ replace BS170 in existing designs?
Only with circuit review: BS107PSTZ has higher RDS(ON) (15–23Ω vs. 5Ω) and higher VDSS (200V vs. 60V), making it less efficient at low voltages but far more robust against transients. It will function electrically but may require gate drive adjustment and thermal reassessment in high-duty-cycle 5V applications.
What is the maximum safe operating temperature for BS107PSTZ?
The absolute maximum junction temperature is +150°C. With RθJA = 200°C/W and PD = 500mW, ambient temperature must remain ≤125°C for safe continuous operation. Derating is required above 25°C ambient-e.g., max power drops to ~375mW at 70°C ambient per linear derating curve in DS33012.
