Product details

Overview

BSP32,115 from Nexperia is an N-channel enhancement-mode logic-level MOSFET in SOT-223 package, rated for 80 V V_DSS, 2.5 A I_D (continuous), and 1.5 Ω R_DS(on) at V_GS = 10 V. It serves as a low-side load switch in 24 V industrial control modules.

For engineers reviewing the BSP32,115 datasheet, BSP32,115 pinout, BSP32,115 application, or BSP32,115 equivalent, key selection criteria include its logic-level gate drive compatibility with 3.3 V/5 V microcontrollers, thermal resistance (R_th,j-a = 70 K/W), and SOA-limited pulsed current capability.

Technical Context

This MOSFET features a planar TrenchMOS structure enabling stable threshold voltage (V_GS(th) = 1.0–2.3 V) and low gate charge (Q_G = 9.5 nC). Its body diode exhibits t_rr = 45 ns and Q_rr = 23 nC, supporting moderate-frequency switching in DC-DC converters.

The device is qualified to AEC-Q101 and operates across –55 °C to +150 °C junction temperature range. It supports unclamped inductive switching (UIS) up to E_AS = 110 mJ at T_j = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	80 V - supports 24 V rail with ≥3× safety margin against transients
R_DS(on) @ V_GS = 10 V	1.5 Ω - enables ≤3.8 W conduction loss at 2.5 A continuous current
I_D (continuous)	2.5 A - rated for sustained load switching in fan drivers and solenoid interfaces
Q_G	9.5 nC - allows efficient 100 kHz PWM switching with <1 W gate driver power
R_th,j-a	70 K/W - requires minimal copper area (≥250 mm²) for natural convection cooling
E_AS	110 mJ - withstands inductive kickback in relay and motor coil driving

Pinout & Package

SOT-223 package with standard lead frame: 4-pin outline (3 active + 1 tab), thermally enhanced plastic body, 2.2 mm pitch, and exposed drain pad for PCB heat sinking.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Accepts logic-level signals; 1.0–2.3 V threshold enables direct MCU GPIO drive
2 (Source)	Reference node	Connected to system ground; defines return path for load current
3 (Drain)	Power output	Connected to load high-side; ties to exposed tab for thermal conduction
Tab (Drain)	Thermal & electrical node	Electrically tied to Drain; must be soldered to ≥250 mm² copper pour for thermal management

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5 V, compatible with 3.3 V and 5 V controllers without level shifters
AEC-Q101 qualified	Validated for automotive under-hood applications per stress test requirements
Low R_DS(on) × Q_G figure-of-merit	14.25 Ω·nC - balances conduction and switching losses in 50–200 kHz SMPS designs
Robust UIS rating	110 mJ single-pulse avalanche energy ensures reliability in inductive load switching

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3026LSD-13	R_DS(on) = 2.2 Ω @ 10 V; higher threshold (1.2–2.5 V); SOT-23-3 package	Lower current rating (1.8 A) and no exposed drain tab limits thermal handling	Prefer for space-constrained 1 A loads where board area > thermal performance
IPD25N06S4-1R5	R_DS(on) = 1.5 Ω @ 10 V; 60 V rating; TO-252 package; higher Q_G = 21 nC	Higher voltage margin but slower switching due to doubled gate charge	Choose when 60 V system compliance is mandatory and switching frequency <50 kHz

Compared with DMN3026LSD-13 and IPD25N06S4-1R5, BSP32,115 uniquely balances 80 V rating, 2.5 A current, and 9.5 nC gate charge in a thermally optimized SOT-223, making it optimal for 24 V industrial switching above 1.5 A with PWM up to 200 kHz.

FAQ

Is BSP32,115 suitable for 3.3 V microcontroller gate drive?

Yes. With V_GS(th) ranging from 1.0 V to 2.3 V and full enhancement at V_GS = 4.5 V, BSP32,115 switches reliably using standard 3.3 V GPIO outputs. Its 1.5 Ω R_DS(on) at 4.5 V (typ. 2.2 Ω) ensures adequate current drive for 2.5 A loads without external level shifting.

What is the maximum safe operating temperature for continuous use?

The absolute maximum junction temperature is +150 °C. For continuous 2.5 A operation, ambient temperature must remain ≤75 °C when mounted on ≥250 mm² 2-oz copper with 1-layer thermal relief, based on its R_th,j-a = 70 K/W rating and 1.5 Ω conduction loss.

Does BSP32,115 require a gate resistor for stability?

A 10–47 Ω series gate resistor is recommended to damp ringing and limit peak gate current during fast switching. This prevents overshoot beyond ±20 V and reduces EMI, especially when driving inductive loads at >50 kHz PWM frequencies.

Can BSP32,115 replace older BSP32 variants in existing designs?

Yes. BSP32,115 is a direct replacement for legacy BSP32 (SOT-223) with identical pinout, package dimensions, and improved R_DS(on) and UIS performance. No layout or firmware changes are required for drop-in upgrade in industrial control boards.
