Product details

Overview

BSS192,135 from Nexperia is a P-channel enhancement-mode vertical D-MOSFET in SOT89 (SC-62) package, rated for −240 V drain-source voltage, 10 Ω typical R_DS(on) at V_GS = −10 V and I_D = −200 mA, and optimized for high-side load switching in industrial control circuits.

For engineers reviewing the BSS192,135 datasheet, BSS192,135 pinout, BSS192,135 application, or BSS192,135 equivalent, this device serves as a medium-power discrete switch with fast turn-on/turn-off times (t_d(on) = 3.2 ns, t_f = 7 ns), low gate charge (Q_G(tot) = 1.9 nC), and robust thermal performance on FR4 PCBs.

Technical Context

This P-channel MOSFET operates in enhancement mode with a gate-source threshold voltage range of −0.8 V to −2.8 V at T_j = 25 °C and supports direct interface with CMOS/TTL logic due to its −10 V gate drive compatibility. Its vertical D-MOS structure enables high breakdown voltage without secondary breakdown limitations.

It delivers stable R_DS(on) up to 150 °C junction temperature (21 Ω max), features low output capacitance (C_oss = 20–30 pF), and maintains safe operating area integrity under pulsed drain currents up to −800 mA (tp ≤ 10 µs).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	−240 V - Withstands high-voltage DC rails in industrial power supplies and relay drivers.
R_DS(on)	10 Ω typ @ V_GS = −10 V, I_D = −200 mA - Enables <100 mW conduction loss at 200 mA load current.
Q_G(tot)	1.9 nC typ - Reduces gate drive power and allows efficient switching at >1 MHz frequencies.
t_f	7 ns typ @ V_DS = −50 V, I_D = −250 mA - Supports clean, low-overshoot transitions in high-speed line drivers.
T_j max	150 °C - Permits operation in enclosed industrial enclosures without active cooling.
I_D cont	−200 mA @ T_amb = 25 °C - Sufficient for driving small solenoids, LED arrays, or logic-level loads.
C_iss	55–90 pF - Minimizes Miller effect and improves noise immunity in high-dV/dt environments.

Pinout & Package

SOT89 (SC-62) plastic surface-mounted package with exposed die pad for enhanced thermal transfer; 3-lead configuration, single-sided copper FR4 mounting pad (1 cm²) recommended.

Pin/Terminal	Circuit Role	Design Meaning
1	Source (S)	Reference node for gate drive; connects to system ground or negative rail in high-side configurations.
2	Drain (D)	High-voltage load connection point; thermally coupled to exposed pad for 4–10 K/W junction-to-solder-point resistance.
3	Gate (G)	CMOS/TTL-compatible control input; requires −10 V for full enhancement; gate leakage <100 nA ensures low standby current.

Key Features

Feature	Design Value
No secondary breakdown	Enables reliable operation under inductive load switching without derating or snubbers.
Direct CMOS/TTL interface	Eliminates level-shifting circuitry when driven by 3.3 V or 5 V microcontrollers.
Very fast switching	Combined t_d(on) + t_r + t_d(off) + t_f < 40 ns ensures minimal transition losses in PWM applications.
Low R_DS(on) drift with temperature	R_DS(on) increases only ~2.1× from 25 °C to 150 °C, supporting stable performance across ambient ranges.
Source-drain diode V_SD	0.86–1.2 V @ I_S = −200 mA - Provides intrinsic freewheeling path for inductive loads without external diode.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2053LK-7	R_DS(on) = 4.5 Ω @ V_GS = −4.5 V; SOT-23 package; lower voltage rating (−20 V)	Better suited for low-voltage logic-level switching; unsuitable for >−60 V rails	Select when gate drive is limited to −4.5 V and V_DS < −20 V; not drop-in for BSS192,135's −240 V use cases.
IPD250N06L3-1R2	R_DS(on) = 1.2 mΩ @ V_GS = −10 V; TO-252 package; 60 V rating; higher current (250 A)	Designed for high-current automotive power stages; over-engineered for 200 mA loads	Choose only if board space allows TO-252 and system requires <1 mΩ conduction loss; excessive cost and size for BSS192,135 applications.

Compared with DMN2053LK-7 and IPD250N06L3-1R2, the BSS192,135 uniquely balances ultra-high voltage capability (−240 V), medium-power SOT89 form factor, and logic-compatible gate drive-making it irreplaceable in industrial high-side switching where voltage margin and thermal footprint are critical.

FAQ

What is the maximum continuous drain current for BSS192,135 at 100 °C ambient?

The maximum continuous drain current is −120 mA at T_amb = 100 °C, per Table 5 Limiting Values. This reflects thermal derating due to reduced heat dissipation at elevated ambient temperatures on standard FR4 PCBs with 1 cm² drain pad.

Does BSS192,135 require a gate resistor for stability?

A gate resistor (typically 10–100 Ω) is recommended to dampen ringing caused by gate loop inductance and MOSFET input capacitance. The device's low Q_G (1.9 nC) and fast switching make it susceptible to oscillation without proper gate control.

Can BSS192,135 be used in linear (analog) regulation mode?

No-it is not characterized or guaranteed for linear operation. The datasheet specifies only switching parameters and safe operating area under pulsed conditions; no SOA curves or thermal resistance data support sustained linear bias.

What is the thermal resistance from junction to solder point (R_th(j-sp)) for BSS192,135?

R_th(j-sp) is 4–10 K/W, per Table 6 Thermal Characteristics. This value assumes mounting on FR4 PCB with standard footprint and reflects efficient heat transfer from die to PCB copper via the exposed drain pad.
