Product details
Overview
BSP135 E6906 from Infineon Technologies is an N-channel enhancement-mode MOSFET in SOT-223 package, rated for 60 V VDS, 1.3 A continuous drain current, and 1.2 W power dissipation at TA = 25°C. It features low gate charge (Qg = 4.5 nC), fast switching, and is optimized for low-voltage DC-DC converter synchronous rectification and load switching in automotive body electronics.
For engineers reviewing the BSP135 E6906 datasheet, BSP135 E6906 pinout, BSP135 E6906 application, or BSP135 E6906 equivalent, key selection criteria include its RDS(on) of 350 mΩ @ VGS = 10 V, thermal resistance RthJA = 125 K/W, and AEC-Q101 qualification - critical for under-hood automotive power management designs.
Technical Context
This discrete MOSFET operates as a single N-channel silicon power switch with logic-level gate drive compatibility (VGS(th) = 1–2.5 V). Its planar trench process enables stable performance across -55°C to +150°C junction temperature range and supports pulsed drain currents up to 5.2 A.
The device integrates intrinsic body diode with reverse recovery time trr = 45 ns and Qrr = 25 nC, making it suitable for freewheeling and synchronous rectifier roles in buck converters and LED drivers where efficiency and EMI control matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum blocking voltage before avalanche; sets upper limit for input rail in 12/24 V automotive systems. |
| RDS(on) @ VGS = 10 V | 350 mΩ - Conduction loss contributor; determines I²R heating at 1.3 A nominal load. |
| ID (continuous) | 1.3 A - Safe steady-state current at TA = 25°C with PCB heatsinking; derates to ~0.7 A at 100°C ambient. |
| Qg | 4.5 nC - Gate charge required for full turn-on; directly impacts switching loss and driver sizing in PWM applications. |
| RthJA | 125 K/W - Junction-to-ambient thermal resistance on standard FR4; defines temperature rise per watt dissipated without added copper. |
| VGS(th) | 1–2.5 V - Threshold voltage range; ensures reliable turn-on with 3.3 V or 5 V microcontroller GPIOs. |
Pinout & Package
Package: SOT-223 (TO-261AA), surface-mount, 4-pin variant with tab-connected drain for thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives gate drive signal; high-impedance input requiring <4.5 nC charge for full enhancement. |
| 2 (Source) | Reference node | Common return path for load current; tied to ground or low-side reference in high-side switch configurations. |
| 3 (Drain) | Power output terminal | Connected to internal die substrate and exposed tab; must be soldered to ≥1 cm² copper pour for thermal management. |
| 4 (Tab / Drain) | Thermal & electrical connection | Electrically identical to Pin 3; provides primary heat path to PCB; not isolated from drain. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Low RDS(on) × Qg figure-of-merit | 1.58 Ω·nC - Balances conduction and switching losses for high-efficiency 100–500 kHz DC-DC operation. |
| Fast body diode recovery | trr = 45 ns - Reduces reverse recovery spikes and associated EMI in hard-switched topologies. |
| Enhancement-mode only | No inherent leakage at VGS = 0 V - Ensures fail-safe off-state in unpowered or floating gate conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP1NK60ZFP (STMicroelectronics) | 600 V rating, 0.8 A ID, higher RDS(on) (7 Ω), TO-92 package | Designed for HV flyback snubbers, not automotive low-voltage loads | Not suitable for 12 V systems due to excessive conduction loss and package thermal limitation. |
| DMN2004LK-7 (Diodes Inc.) | 20 V VDS, 4.2 A ID, RDS(on) = 30 mΩ @ 4.5 V, SOT-23 package | Optimized for USB-powered portable devices, not automotive ambient or reliability requirements | Lacks AEC-Q101 qualification and thermal robustness for under-hood deployment. |
Compared with STP1NK60ZFP and DMN2004LK-7, BSP135 E6906 uniquely balances 60 V rating, AEC-Q101 compliance, SOT-223 thermal capability, and logic-level gate drive - making it the only viable choice for cost-sensitive, space-constrained 12 V automotive load switches requiring production-grade reliability.

FAQ
Is BSP135 E6906 pin-compatible with BSP125 or BSP115?
No. BSP135 E6906 uses SOT-223 with drain-connected tab, while BSP125 (SOT-23) and BSP115 (SOT-223 but different pin 1 assignment) have distinct pinouts and thermal footprints. Mechanical and electrical substitution requires PCB redesign and thermal validation.
What is the maximum safe operating frequency when used as a synchronous rectifier?
At 1.3 A load and 12 V input, BSP135 E6906 supports up to 500 kHz switching with adequate gate drive (≥100 mA peak) and PCB thermal relief. Above this, switching losses dominate due to Qg = 4.5 nC and tf/tr ≈ 15 ns, risking thermal runaway without active cooling.
Does BSP135 E6906 require a gate resistor in automotive 12 V applications?
Yes - a 10–22 Ω series gate resistor is recommended to dampen ringing caused by PCB trace inductance and MOSFET input capacitance (Ciss = 180 pF), especially when driven by fast MCU GPIOs. This prevents false turn-on and EMI emissions in noisy vehicle environments.
Can BSP135 E6906 be used in linear regulator mode?
No. Its SOA curve limits linear operation to <0.15 W at 25°C ambient. At VDS = 5 V and ID = 0.3 A, junction temperature exceeds 150°C within milliseconds without forced cooling - making it unsuitable for pass-element use.
