Product details
Overview
BSS315PL6327HTSA1 from Infineon Technologies is a P-channel enhancement-mode MOSFET in SOT-23 package, rated for -20 V drain-source voltage, -2.9 A continuous drain current at TC = 25 °C, and 110 mΩ maximum RDS(on) at VGS = -4.5 V. It serves as a low-side load switch in portable power management circuits.
For engineers reviewing the BSS315PL6327HTSA1 datasheet, BSS315PL6327HTSA1 pinout, BSS315PL6327HTSA1 application, or BSS315PL6327HTSA1 equivalent, key selection criteria include guaranteed RDS(on) at logic-level gate drive, specified reverse diode recovery time, and thermal resistance (RthJA = 250 K/W) for PCB-constrained space.
Technical Context
This MOSFET employs trench-stop technology to achieve low on-resistance with fast switching characteristics. Its gate threshold voltage (VGS(th)) is tightly specified between –0.5 V and –1.2 V, enabling reliable turn-on with 1.8 V–3.3 V microcontroller I/O.
The integrated body diode exhibits trr = 35 ns and Qrr = 12 nC at IF = –2.9 A, supporting efficient flyback energy recovery in DC-DC converter synchronous rectification and LED driver high-side return paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | –20 V: Maximum allowable drain-to-source voltage under blocking conditions; defines safe operating range in 3.3 V/5 V rail-switching applications. |
| ID (cont) | –2.9 A @ TC = 25 °C: Continuous current capability with standard SOT-23 copper pad layout; derates to ~1.8 A at 70 °C ambient. |
| RDS(on) | 110 mΩ max @ VGS = –4.5 V: Ensures <100 mW conduction loss at 1 A load; validated per JEDEC JESD47 stress testing. |
| Qg | 6.2 nC: Total gate charge determining drive strength requirement; enables <100 ns turn-on with 10 mA gate driver. |
| trr | 35 ns: Reverse recovery time of intrinsic body diode; critical for minimizing switching loss in buck converter freewheeling stage. |
| RthJA | 250 K/W: Junction-to-ambient thermal resistance on 1-in² FR4 with 2 oz Cu; sets maximum power dissipation limit at 320 mW in still air. |
Pinout & Package
Supplied in SOT-23 (TO-236) plastic surface-mount package with standard 3-pin configuration and 1.3 mm pitch. Moisture sensitivity level (MSL) is 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Receives logic-level voltage to modulate channel conductivity; requires no external pull-down for default-off operation. |
| 2 (Source) | Reference node | Connected to system ground or higher-potential rail depending on low/high-side topology; defines VGS reference. |
| 3 (Drain) | Power output | Switches load current path; routed to avoid coupling noise into sensitive analog sections due to dV/dt sensitivity. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Guaranteed turn-on with 1.8 V microcontroller GPIO; eliminates need for level-shifting circuitry in battery-powered systems. |
| Low gate charge (Qg) | 6.2 nC enables fast switching with minimal driver power consumption-critical for duty-cycled power gating in wearables. |
| Specified body diode recovery | trr = 35 ns and Qrr = 12 nC allow predictable snubber design and reduced EMI in discontinuous conduction mode converters. |
| Robust avalanche rating | Rated for single-pulse avalanche energy EAS = 35 mJ; withstands inductive kickback during hot-plug events without failure. |
Applications
| USB Port Power Switching | Load Switch in IoT Sensor Node |
|---|---|
Use Scenario: Enables/disables 5 V USB VBUS to peripheral devices under firmware control while meeting USB-IF inrush current limits. IC Role / Device Role / Timing Role: Low-side power switch controlling VBUS path; operates in static on/off states with <1 µs transition time. Use Value: RDS(on) ≤ 110 mΩ ensures <30 mV drop at 250 mA, preserving downstream voltage margin; MSL-1 rating supports reflow-only assembly. | Use Scenario: Powers BLE radio and environmental sensors only during active measurement cycles to extend coin-cell battery life beyond 2 years. IC Role / Device Role / Timing Role: Load switch isolating supply to subsystem; driven by MCU GPIO with configurable enable timing. Use Value: Qg = 6.2 nC allows full turn-on within 100 ns using standard 10 mA IO, minimizing wake-up latency and leakage-induced sleep current. |
| Reverse Polarity Protection | LED Backlight Dimming Control |
Use Scenario: Placed in series with input rail to block reverse-connected batteries or adapters in handheld medical instruments. IC Role / Device Role / Timing Role: P-channel pass element configured as ideal diode; conducts only when VIN > VOUT + |VGS(th)|. Use Value: VGS(th) range (–0.5 V to –1.2 V) ensures consistent turn-on across temperature and process variation; RDS(on) minimizes forward drop. | Use Scenario: Controls current path to white LED string in automotive instrument cluster backlight, synchronized with PWM dimming signal. IC Role / Device Role / Timing Role: High-side current sink switch modulating LED return path; switched at 1–2 kHz to avoid audible noise. Use Value: trr = 35 ns prevents tail current overlap during PWM edges, reducing thermal stress and improving dimming linearity. |
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 | RDS(on) = 90 mΩ @ VGS = –4.5 V; Qg = 5.8 nC; SOT-23 package | Lower on-resistance improves efficiency at >1.5 A loads but has tighter VGS(th) tolerance (–0.7 V to –1.1 V) | Select when lower conduction loss is prioritized over gate drive margin at 1.8 V. |
| SI2301DDS-T1-BE3 | RDS(on) = 130 mΩ @ VGS = –4.5 V; Qg = 7.5 nC; same SOT-23 footprint | Higher gate charge increases driver demand; body diode trr not specified in datasheet | Choose for cost-sensitive designs where moderate RDS(on) and unspecified recovery are acceptable. |
Compared with DMN2053LK-7 and SI2301DDS-T1-BE3, BSS315PL6327HTSA1 offers balanced trade-offs: verified trr, robust VGS(th) range, and JEDEC-qualified reliability-making it preferred for safety-critical portable medical and industrial sensor nodes.

FAQ
What is the maximum pulsed drain current rating for BSS315PL6327HTSA1?
The device supports IDM = –8.7 A for pulse widths ≤ 10 µs with duty cycle ≤ 1%, as defined in the Absolute Maximum Ratings table. This rating assumes case temperature remains below 25 °C and accounts for transient thermal impedance limitations in the SOT-23 package.
Does BSS315PL6327HTSA1 have built-in ESD protection?
Yes, it features HBM ESD rating of ±2 kV per JESD22-A114, verified through standardized testing. No external TVS diode is required for typical board-level ESD immunity up to IEC 61000-4-2 Level 2 (±4 kV contact discharge), provided proper PCB layout practices are followed.
Can BSS315PL6327HTSA1 be used in linear regulation mode?
No-it is not characterized or qualified for linear (ohmic) operation. The Safe Operating Area (SOA) curve shows limited DC capability beyond 100 ms, and thermal runaway risk increases above VDS = –5 V at ID > –1 A due to positive temperature coefficient of RDS(on).
What is the recommended solder profile for BSS315PL6327HTSA1?
Reflow must comply with IPC/JEDEC J-STD-020D MSL-1 requirements: peak temperature 260 °C for ≤ 10 seconds, ramp-up rate ≤ 3 °C/s, and time above 217 °C limited to 60–150 seconds. Preheat dwell at 150–200 °C for 60–120 seconds ensures uniform heating of the SOT-23 body.
