Product details

Overview

BSP220,115 from NXP Semiconductors (formerly Philips) is a P-channel enhancement-mode vertical D-MOS transistor in SOT223 package, designed for high-speed switching in relay and line transformer driver circuits. It features −200 V drain-source voltage rating, 225 mA DC drain current, 12 Ω R_DS(on) at −I_D = 200 mA / −V_GS = 10 V, 2.8 V gate-source threshold voltage, and 1.5 W total power dissipation at T_amb = 25 °C.

For engineers reviewing the BSP220,115 datasheet, BSP220,115 pinout, BSP220,115 application, or BSP220,115 equivalent, this part is selected for low-voltage logic-level P-channel switching where compact footprint, fast turn-off (20–30 ns), and direct CMOS/TTL interface capability are required in industrial control and telecom line drivers.

Technical Context

This device operates as a normally-off P-channel MOSFET with vertical D-MOS architecture optimized for low on-resistance and high-speed switching. Its gate-source threshold voltage range (0.8–2.8 V) enables reliable turn-on from standard logic outputs, while absence of secondary breakdown supports robust pulsed operation.

Thermal design relies on the exposed drain pad in SOT223 - requiring ≥6 cm² copper area on epoxy PCB for rated 1.5 W dissipation. Junction-to-ambient thermal resistance is 83.3 K/W under specified mounting conditions, and capacitance profile (C_iss = 65–90 pF, C_oss = 20–30 pF) supports stable high-frequency switching up to several MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
−V_DS	200 V - supports isolation and drive in 100–170 V AC line-derived circuits without derating.
−I_D (DC)	225 mA - sufficient for driving small relays, LED arrays, or bias networks in telecom interfaces.
R_DS(on)	12 Ω max at −200 mA/−10 V - ensures <1.2 V drop at full rated current, minimizing conduction loss.
−V_GS(th)	0.8–2.8 V - guarantees turn-on with 3.3 V or 5 V logic, including margin for temperature drift.
t_off	20–30 ns - enables clean switching in >10 MHz PWM or pulse transformer applications.
C_iss	65–90 pF - limits gate drive current demand and supports fast edge rates with low-impedance drivers.
P_tot	1.5 W at T_amb = 25 °C - defines maximum continuous power handling under standard PCB layout conditions.

Pinout & Package

SOT223 package with exposed drain pad for thermal conduction; 4-pin surface-mount outline featuring integrated heat-sink capability via large copper area requirement (≥6 cm²).

Pin/Terminal	Circuit Role	Design Meaning
1	Gate	High-impedance MOSFET control input; requires no continuous current, only capacitive charge/discharge.
2	Drain	Main high-side switching node; electrically and thermally connected to exposed metal pad on package underside.
3	Source	Reference terminal for gate drive and load return path; tied to system ground or negative rail in high-side configuration.
4	Drain	Second drain connection - paralleled internally with Pin 2 to enhance current capacity and thermal spreading.

Key Features

Feature	Design Value
Low R_DS(on)	12 Ω max enables <250 mW conduction loss at 200 mA, reducing thermal stress in space-constrained designs.
Direct CMOS/TTL interface	Threshold voltage range (0.8–2.8 V) ensures compatibility with 3.3 V and 5 V logic families without level-shifting.
No secondary breakdown	Vertical D-MOS structure eliminates safe operating area (SOA) limitations during transient overloads.
High-speed switching	20–30 ns turn-off time supports clean signal edges in pulse transformers and solid-state relay timing circuits.

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
DMG2305U-7	R_DS(on) = 45 mΩ @ −4.5 V (vs. 12 Ω @ −10 V); SOT-23 package; lower voltage rating (−20 V).	Not suitable for 100+ V line-derived circuits; limited to low-voltage logic control only.	Select only when replacing in 3.3 V systems with <20 V supply and strict size constraints.
SI2305DS-T1-E3	R_DS(on) = 55 mΩ @ −4.5 V; SOT-23; −20 V V_DS; higher gate charge than BSP220.	Cannot replace in high-voltage relay or transformer driver roles due to voltage limitation.	Prefer for battery-powered portable devices where ultra-low on-resistance at low V_GS is critical.

Compared with DMG2305U-7 and SI2305DS-T1-E3, the BSP220,115 uniquely supports 200 V blocking and delivers usable R_DS(on) at −10 V gate drive - making it irreplaceable in legacy telecom and industrial line-powered switching where voltage headroom and thermal robustness are non-negotiable.

FAQ

What is the maximum continuous drain current for BSP220,115?

The BSP220,115 supports a maximum DC drain current of 225 mA at T_amb = 25 °C with proper PCB copper area (≥6 cm² for the drain pad). At elevated ambient temperatures, current must be reduced per the derating curve - e.g., ~150 mA at 70 °C - to maintain junction temperature below 150 °C.

Can BSP220,115 be driven directly by a 3.3 V microcontroller GPIO?

Yes - its gate-source threshold voltage ranges from 0.8 V to 2.8 V, ensuring reliable turn-on with 3.3 V logic. However, R_DS(on) is specified at −10 V V_GS; at 3.3 V, on-resistance increases significantly (typical ~40–60 Ω), limiting usable current to ~50 mA for low-loss operation.

Why does BSP220,115 have four pins in SOT223 but only three terminals?

Pin 2 and Pin 4 are both internally connected to the drain and share the same exposed metal pad on the package underside. This dual-drain configuration improves current handling and thermal spreading without requiring additional internal routing - a mechanical redundancy for reliability and manufacturability.

Is BSP220,115 suitable for automotive applications?

No - it is not qualified to AEC-Q101 or any automotive-grade reliability standard. The datasheet explicitly excludes life-support and safety-critical applications, and its 150 °C maximum junction temperature and lack of automotive qualification make it unsuitable for under-hood or ADAS systems.
