Product details
Overview
BS250KL-TR1-E3 from Vishay Siliconix is a P-channel enhancement-mode TrenchFET® power MOSFET rated for −60 V drain-source voltage, 6 Ω rDS(on) at VGS = −10 V, and −0.27 A continuous drain current at 25 °C. It serves as a low-side load switch in battery-powered systems, relay/solenoid drivers, and DC-DC converter synchronous rectification.
For engineers reviewing the BS250KL-TR1-E3 datasheet, BS250KL-TR1-E3 pinout, BS250KL-TR1-E3 application, or BS250KL-TR1-E3 equivalent, key selection criteria include its −1 to −3 V gate threshold, ESD protection (2000 V HBM), TO-92 package thermal resistance (156 °C/W), and verified performance in motor control and lamp driving circuits.
Technical Context
This device operates as a normally-off P-channel switch requiring negative gate drive relative to source. Its trench-based silicon structure enables low on-resistance with minimal gate charge (Qg = 1.7–3 nC) and fast switching (tr = 15.5–25 ns, tf = 12.5–20 ns).
It features an integrated body diode with VSD = −0.9 to −1.4 V at IS = −200 mA and exhibits stable rDS(on) over temperature (normalized to 1.2× at 125 °C), supporting reliable operation in industrial ambient conditions up to 70 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | −60 V - supports input rails up to 48 V DC without derating in off-state |
| rDS(on) | 6 Ω @ VGS = −10 V - delivers ≤60 mW conduction loss at −100 mA load |
| VGS(th) | −1 to −3 V - ensures full enhancement with standard logic-level negative gate drive |
| ID Continuous | −0.27 A @ 25 °C - suitable for sub-300 mA loads with PCB copper heatsinking |
| Qg | 1.7–3 nC - enables efficient gate driving with low-power controllers |
| RthJA | 156 °C/W - requires minimum 0.5 cm² 2-oz copper pad for safe 0.51 W dissipation at 70 °C ambient |
| ESD Rating | 2000 V HBM - protects against handling damage during manual assembly and board test |
Pinout & Package
BS250KL-TR1-E3 is housed in a TO-226AA (TO-92) plastic package with 3 leads. The package is surface-mount compatible when used with lead-form variant TO-92-18RM, and features standard through-hole mounting per JEDEC TO-92 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Lead 1) | Source (S) | Main current return path; connected to system ground or high-side rail in high-side switch configurations |
| 2 (Lead 2) | Drain (D) | Load connection node; carries full switched current and must be routed with adequate trace width |
| 3 (Lead 3) | Gate (G) | Control input; requires negative voltage relative to source to turn on; sensitive to ESD |
Key Features
| Feature | Design Value |
|---|---|
| TrenchFET® technology | Enables 6 Ω rDS(on) in TO-92 - rare for −60 V P-channel devices in this package |
| ESD protection | 2000 V HBM - eliminates need for external ESD clamps in low-complexity designs |
| Low gate threshold | −1 to −3 V - allows direct interface with microcontroller GPIOs using simple level-shifting resistors |
| Body diode integration | VSD = −0.9 to −1.4 V - supports freewheeling in inductive loads like relays and solenoids |
| Thermal stability | rDS(on) increases only 20% at 125 °C - maintains predictable power loss across operating range |
Applications
| Relay/Solenoid Driver | Lamp & Display Control |
|---|---|
Use Scenario: Driving 12 V automotive relays or 24 V industrial solenoids with microcontroller output. IC Role / Device Role / Timing Role: Low-side P-channel switch controlling coil current path to ground. Use Value: −0.27 A rating and −60 V breakdown safely handle back-EMF spikes up to 40 V, eliminating need for external flyback diodes in many cases. | Use Scenario: Dimming or on/off control of LED arrays and vacuum fluorescent displays in portable instruments. IC Role / Device Role / Timing Role: Constant-current sink or PWM-controlled load switch. Use Value: Low rDS(on) minimizes voltage drop across the switch, preserving display brightness and reducing thermal stress on PCB traces. |

Use Scenario: Power sequencing and load isolation in handheld medical monitors and IoT sensors powered by Li-ion cells. IC Role / Device Role / Timing Role: Reverse-polarity and load-disconnect protection switch. Use Value: −1 to −3 V VGS(th) allows clean turn-on with single-cell 3.3 V supply and simple resistor divider gate bias. | Use Scenario: Synchronous rectification or auxiliary gate drive in buck/boost converters under 1 W output. IC Role / Device Role / Timing Role: Secondary-side switch replacing Schottky diode to improve efficiency. Use Value: 6 Ω rDS(on) reduces conduction loss by >40% vs. typical 0.4 V Schottky at 100 mA, increasing light-load efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TP0610KL-TR1 | Same die, identical electrical specs, different marking and ordering code | No functional difference; used interchangeably in same designs | Select TP0610KL-TR1 if sourcing from legacy BOMs or distributor stock with that part number |
| DMN2011UW-7 | −20 V VDS, 2.5 Ω rDS(on) @ −4.5 V, SOT-323 package, lower voltage rating | Not suitable for 48 V systems; better for 3.3/5 V logic-driven loads | Choose DMN2011UW-7 only for low-voltage, space-constrained designs where −60 V rating is unnecessary |
Compared with TP0610KL-TR1, BS250KL-TR1-E3 offers identical performance but distinct traceability and packaging; versus DMN2011UW-7, it trades higher voltage capability and TO-92 thermal mass for larger footprint and lower max current - making BS250KL-TR1-E3 optimal for robust 24–48 V industrial switching where reliability outweighs miniaturization.

FAQ
What is the maximum continuous drain current for BS250KL-TR1-E3 at 70 °C ambient?
The BS250KL-TR1-E3 supports −0.22 A continuous drain current at 70 °C ambient temperature, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-92 package and must be applied when designing for sustained operation above 25 °C. Always verify junction temperature using RthJA = 156 °C/W and actual power dissipation in your layout.
Is BS250KL-TR1-E3 pin-compatible with TP0610KL-TR1?
Yes - BS250KL-TR1-E3 and TP0610KL-TR1 share identical TO-92 pinout (Source, Drain, Gate on leads 1–2–3), electrical specifications, and thermal characteristics. They differ only in marking and ordering code; both are manufactured by Vishay Siliconix from the same die and process, and may be substituted without PCB modification.
Does BS250KL-TR1-E3 require a gate resistor for microcontroller drive?
A series gate resistor (typically 10–100 Ω) is recommended when driving BS250KL-TR1-E3 from a microcontroller GPIO to limit peak gate current and damp ringing. While not strictly required for functionality, it improves EMI performance and prevents potential latch-up in weak-drive scenarios - especially important given the device's 285 Ω internal gate resistance and 1.7–3 nC Qg.
Can BS250KL-TR1-E3 be used in high-side switch configurations?
Yes - BS250KL-TR1-E3 is a P-channel MOSFET optimized for high-side switching. To operate correctly, the gate must be driven negative relative to the source (e.g., source tied to VIN, gate pulled to ground to turn on). Its −60 V VDS rating and −1 to −3 V VGS(th) make it suitable for 24–48 V high-side loads, provided gate drive circuitry accommodates the required voltage swing.
What is the safe operating area (SOA) limitation for BS250KL-TR1-E3 in pulse applications?
The BS250KL-TR1-E3 SOA curve shows pulse drain current is limited to −1.0 A for durations ≤1 ms at VDS = −30 V. At longer pulses or higher voltages, operation must stay within the rDS(on)-limited, BVDSS-limited, or ID(on)-limited boundaries shown in the datasheet Figure 12. Exceeding these risks thermal runaway or avalanche failure.
