Product details
Overview
IRF5850TRPBF from Infineon Technologies (formerly International Rectifier) is a dual P-channel enhancement-mode MOSFET in TSOP-6 package, rated for -20 V VDS, 0.135 Ω RDS(on) at VGS = -4.5 V and ID = -2.2 A, with integrated body diodes and low gate charge (Qg = 3.6 nC typ). It enables compact high-efficiency load switching in portable battery-powered systems.
For engineers reviewing the IRF5850TRPBF datasheet, IRF5850TRPBF pinout, IRF5850TRPBF application, or IRF5850TRPBF equivalent, key selection criteria include its dual-channel P-MOS topology, thermal resistance (RθJA = 130 °C/W), pulsed current capability (-9.0 A), and lead-free/halogen-free TSOP-6 footprint optimized for space-constrained PCB layouts.
Technical Context
This device integrates two identical P-channel HEXFET power MOSFETs in a single TSOP-6 package, sharing source terminals internally to support dual independent high-side switch configurations. Its gate threshold voltage range (-0.45 V to -1.2 V) ensures reliable turn-on with standard logic-level drive down to -2.5 V.
Designed for bidirectional load control and reverse-polarity protection, it features low RDS(on) temperature coefficient (0.011 V/°C), fast switching (tr = 14 ns, tf = 28 ns), and body diode parameters validated at -0.96 A (VSD = -1.2 V, trr = 23–35 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20 V - Maximum drain-source blocking voltage for high-side switch placement in ≤20 V rail systems. |
| RDS(on) | 0.135 Ω @ VGS = -4.5 V, ID = -2.2 A - Enables <150 mW conduction loss per channel at full rated current. |
| ID (cont) | -2.2 A @ TA = 25°C - Sustained current per channel without derating; supports dual 2.2 A loads in same footprint as one SOT-23. |
| Qg | 3.6 nC (typ) - Low total gate charge reduces driver power demand and enables efficient 1 MHz-class switching. |
| RθJA | 130 °C/W - Thermal resistance measured on FR-4 board; defines maximum power dissipation before junction exceeds 150°C. |
| VGS(th) | -0.45 to -1.2 V - Ensures guaranteed turn-on with -2.5 V logic signals and stable operation across temperature. |
| tr/tf | 14 ns / 28 ns - Fast edge rates minimize switching losses in DC-DC and load-switching applications. |
Pinout & Package
TSOP-6 surface-mount package (3.05 mm × 1.6 mm × 1.0 mm), thermally enhanced with exposed drain pad. Dual die configuration shares Source (S) pins (pins 2 & 5); Gate (G) and Drain (D) are independently accessible per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Gate 1 (G1) | Controls first P-MOS channel; accepts logic-level negative gate drive relative to source. |
| Pin 2 | Source 1 (S1) | Common source node for Channel 1; electrically tied to Pin 5 for dual-source configuration. |
| Pin 3 | Drain 1 (D1) | High-side output terminal for Channel 1; connects to load supply rail. |
| Pin 4 | Drain 2 (D2) | High-side output terminal for Channel 2; independent of D1 for dual-load isolation. |
| Pin 5 | Source 2 (S2) | Common source node for Channel 2; internally bonded to Pin 2 for shared-source operation. |
| Pin 6 | Gate 2 (G2) | Controls second P-MOS channel; fully independent gate input for asynchronous switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual P-channel integration | Two matched -20 V, 0.135 Ω MOSFETs in single TSOP-6 - replaces two discrete SOT-23 devices, saving >40% board area. |
| Ultra-low RDS(on) | 0.135 Ω @ -4.5 V - Reduces conduction loss by >30% vs. comparable P-MOSFETs at 2 A load current. |
| Low gate charge | Qg = 3.6 nC - Enables efficient driving from microcontroller GPIOs without external buffer stages. |
| Lead-free & halogen-free | RoHS-compliant construction with Cu-wire bonding - meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1). |
| Body diode performance | VSD = -1.2 V @ -0.96 A, trr = 23 ns - Supports synchronous rectification and reverse-current blocking in battery paths. |
Applications
| Battery Protection Circuit | USB Power Delivery Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7851DP-T1-GE3 | Higher RDS(on) (0.22 Ω @ -4.5 V), larger SO-8 package, higher Qg (6.5 nC) | Less suitable for space-constrained designs; better thermal handling (RθJA = 62 °C/W) | Prefer when board layout allows SO-8 and higher thermal mass is needed for sustained >1.5 A loads. |
| DMC3025LSD-13 | Lower VDS (-12 V), smaller 2×2 mm WDFN, lower RDS(on) (0.095 Ω), but no dual-source tie | Requires separate source routing; unsuitable for shared-source OR-ing topologies | Choose when independent source connections are acceptable and 12 V max system voltage applies. |
Compared with Si7851DP-T1-GE3 and DMC3025LSD-13, IRF5850TRPBF uniquely combines dual-source integration, ultra-low RDS(on), and TSOP-6 footprint-making it optimal for compact, dual-rail battery management where board area and conduction loss are critical.

FAQ
What is the maximum continuous drain current per channel at 70°C ambient?
The IRF5850TRPBF supports -1.8 A continuous drain current per channel at TA = 70°C with VGS = -4.5 V, based on its 0.62 W power dissipation rating and 130 °C/W thermal resistance. Derating follows linear 7.7 mW/°C beyond 70°C ambient.
Can the two channels be used independently with separate source connections?
No-the TSOP-6 pinout ties Source 1 (Pin 2) and Source 2 (Pin 5) internally; they share a common source node. Independent source routing is not supported. For isolated sources, discrete single-channel P-MOSFETs must be used.
Is the body diode rated for reverse recovery in synchronous rectification?
Yes-the body diode has characterized reverse recovery time (trr = 23–35 ns) and charge (Qrr = 7.7–12 nC) at di/dt = -100 A/μs, making it suitable for moderate-frequency (<500 kHz) synchronous rectification in buck converters and OR-ing circuits.
Does IRF5850TRPBF require gate resistors for EMI control in high-speed switching?
Yes-gate resistors (typically 5–22 Ω) are recommended to dampen ringing caused by parasitic inductance in gate loops. The device's low Qg (3.6 nC) and fast tr/tf make it susceptible to oscillation without controlled gate drive impedance.
