Product details

Overview

BSR315PL6327HTSA1 from Infineon Technologies is a P-channel enhancement-mode logic-level SIPMOS® small-signal MOSFET in SC-59 (PG-SC59) package, rated for -60 V V_DS, 0.8 Ω R_DS(on) at V_GS = -4.5 V and I_D = -0.49 A, avalanche-rated, AEC-Q101 qualified, and RoHS/halogen-free compliant - used in automotive load switching and low-power DC-DC converter high-side control.

For engineers reviewing the BSR315PL6327HTSA1 datasheet, BSR315PL6327HTSA1 pinout, BSR315PL6327HTSA1 application, or BSR315PL6327HTSA1 equivalent, key selection criteria include logic-level gate drive compatibility with 3.3 V/5 V microcontrollers, -60 V blocking capability, 0.8 Ω on-resistance at -4.5 V, AEC-Q101 qualification for automotive use, and SC-59 footprint compatibility with SOT-23 layouts.

Technical Context

This device operates as a single P-channel MOSFET with enhancement-mode threshold behavior (V_GS(th) = -1.0 to -2.0 V), designed for low-voltage logic-driven switching where gate drive voltage is constrained to ≤5 V. Its R_DS(on) remains stable across T_j = 25–150 °C, and it features integrated avalanche energy rating (E_AS = 24 mJ at I_D = 0.62 A).

The SC-59 package provides thermal resistance R_thJA = 250 K/W (minimal footprint, steady state), and its dynamic parameters include C_iss = 176 pF, t_r = 46 ns, and Q_g = 6 nC - enabling fast, efficient switching in space-constrained automotive and industrial control circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - supports 48 V automotive systems and industrial 24–48 V rails without derating
R_DS(on) max	0.8 Ω @ V_GS = -4.5 V, I_D = -0.49 A - enables low conduction loss in 3.3 V/5 V logic-controlled switches
I_D continuous	-0.62 A @ T_A = 25 °C - suitable for LED drivers, sensor biasing, and low-current power path control
V_GS(th)	-1.0 to -2.0 V - ensures reliable turn-on with standard logic-level outputs (e.g., MCU GPIO)
E_AS	24 mJ - withstands inductive load switching transients without external snubbers in automotive solenoid control
Q_g	6 nC - allows fast switching with low gate driver current demand (e.g., <1 mA peak at 1 MHz)
C_iss	176 pF - limits capacitive loading on driving MCU pins while maintaining EMI control

Pinout & Package

The BSR315PL6327HTSA1 is housed in an SC-59 (PG-SC59) surface-mount package - identical footprint and pinning to industry-standard SOT-23 and SuperSOT-23, enabling drop-in PCB layout reuse.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Source terminal of P-channel MOSFET	Connected to higher potential rail (e.g., battery +); defines reference for gate drive and current return path
2 (Gate)	Control electrode	Receives logic-level voltage (≤5 V); requires no level-shifting for direct MCU interface
3 (Drain)	Current output terminal	Switches load to ground; handles bidirectional current during body diode conduction in flyback paths

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = -4.5 V, eliminating need for gate driver ICs in 3.3 V/5 V systems
AEC-Q101 qualification	Validated for automotive temperature range (-40 to +150 °C) and mechanical stress per JESD47
Avalanche energy rating	24 mJ single-pulse rating enables robust operation in inductive load switching without external protection
Halogen-free & RoHS	Complies with IEC61249-2-21 and EU RoHS Directive 2011/65/EU for eco-compliant manufacturing
SOT-23 footprint compatibility	SC-59 package allows reuse of existing SOT-23 land patterns and pick-and-place tooling

Applications

IC Role / Device Role / Timing Role: Low-leakage power enable switch isolating sensor supply during sleep mode.

Use Value: I_DSS ≤ -1 µA at 25 °C and -100 µA at 150 °C minimizes standby current drain in battery-powered edge nodes.

LED Lighting Driver

Low-Power DC-DC Converter

Use Scenario: Constant-current dimming control for automotive interior LEDs using PWM.

IC Role / Device Role / Timing Role: Synchronous rectifier and current sink switch in buck-based LED driver stage.

Use Value: Fast t_r/t_f (46/30 ns) and low Q_g (6 nC) support >100 kHz PWM without gate driver overhead.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2053LK-7	V_DS = -20 V, R_DS(on) = 0.35 Ω @ -4.5 V - lower voltage rating, lower on-resistance	Not suitable for 48 V systems; limited to ≤12 V loads	Select only for low-voltage consumer electronics where -60 V capability is unnecessary
FDV303P	V_DS = -30 V, R_DS(on) = 1.3 Ω @ -4.5 V - higher on-resistance, no AEC-Q101 qualification	Lacks automotive qualification and avalanche rating; intended for commercial-grade applications	Acceptable for cost-sensitive industrial prototypes but not for production automotive designs

Compared with DMN2053LK-7 and FDV303P, the BSR315PL6327HTSA1 uniquely combines -60 V rating, AEC-Q101 compliance, and 0.8 Ω R_DS(on) at -4.5 V - making it the only option qualified for safety-critical 48 V automotive switching where both voltage margin and logic-level drive are mandatory.

FAQ

Is BSR315PL6327HTSA1 pin-compatible with standard SOT-23 discrete MOSFETs?

Yes - the SC-59 package has identical footprint and pinout (Source-Gate-Drain on pins 1–2–3) to SOT-23 and SuperSOT-23, allowing direct PCB layout reuse without redesign. Mechanical dimensions and solder pad spacing match JEDEC TO-236AB standards.

What is the maximum junction temperature and thermal derating behavior?

The BSR315PL6327HTSA1 supports T_j up to +150 °C. At T_A = 70 °C, continuous drain current derates to -0.49 A; R_DS(on) increases by ~30% from 25 °C to 150 °C per published curves (Rev 1.06, page 6). Thermal resistance R_thJA is 250 K/W under minimal footprint conditions.

Does this part include an integrated body diode, and what are its characteristics?

Yes - it features a monolithic parasitic body diode with I_S = -0.56 A continuous forward current, V_SD = -0.82 to -1.2 V at I_F = -0.62 A and T_j = 25 °C, and t_rr = 32–48 ns. This enables freewheeling in inductive loads and synchronous rectification in buck topologies.

Can BSR315PL6327HTSA1 be used in linear (analog) regulation mode?

No - it is optimized for switching operation only. The R_DS(on) variation with V_GS and temperature, combined with limited SOA in linear region (see page 4 Safe Operating Area chart), makes it unsuitable for sustained linear regulation. Use only in saturated on/off states.
