Product details
Overview
BSP149H6906XTSA1 from Infineon Technologies is an N-channel depletion-mode SIPMOS® small-signal transistor rated for 200 V drain-source breakdown voltage, 3.5 Ω maximum RDS(on) at VGS = 0 V, and 0.14 A minimum IDSS, qualified to AEC-Q101 for automotive use in high-reliability load switching and voltage clamping circuits.
For engineers reviewing the BSP149H6906XTSA1 datasheet, BSP149H6906XTSA1 pinout, BSP149H6906XTSA1 application, or BSP149H6906XTSA1 equivalent, key selection criteria include its dv/dt rating (6 kV/µs), VGS(th) banding (H6906 indicates sorted threshold voltage), and SOT-223 package thermal performance (RthJA = 70 K/W with 6 cm² copper).
Technical Context
This depletion-mode MOSFET operates with gate-source voltage ranging from –3 V to +10 V, enabling normally-on behavior ideal for fail-safe biasing and high-side current source applications. Its integrated body diode supports reverse recovery times under 65 ns and Qrr ≤ 90 nC at 100 V.
The device features a low gate charge profile (Qg = 11–14 nC) and fast switching dynamics (tr ≤ 5.1 ns, tf ≤ 31 ns), optimized for high-frequency power control in compact automotive and industrial modules where dv/dt immunity and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR(DSS) | 200 V - Withstands up to 200 V drain-source voltage before avalanche conduction begins, enabling use in 12–48 V automotive bus protection. |
| RDS(on),max | 3.5 Ω at VGS = 0 V - Defines on-resistance under zero-gate-bias operation, critical for passive current sourcing in bias networks. |
| IDSS,min | 0.14 A - Minimum saturation current at VGS = 0 V, ensuring predictable baseline conduction without gate drive. |
| dv/dt rating | 6 kV/µs - Immune to rapid voltage transients, preventing false turn-on in noisy motor drive or ignition systems. |
| VGS(th) band | H6906 - Indicates VGS(th) sorted to –1.5 V to –1.3 V range, enabling tighter matching in parallel configurations. |
| Ptot | 1.8 W at TA = 25 °C - Maximum continuous power dissipation on standard PCB layout, supporting thermally constrained space-constrained designs. |
| RthJA | 70 K/W with 6 cm² copper - Thermal resistance enables stable junction temperature below 150 °C at 0.53 A ambient-limited current. |
Pinout & Package
Package: PG-SOT223 (4-pin variant with exposed drain pad). Pin 1 = Gate, Pin 2 = Source, Pin 3 = Drain (tab), Pin 4 = Drain (soldering point). The exposed drain tab provides low thermal resistance path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate terminal | Controls channel conduction; requires no active drive for default-on operation due to depletion-mode structure. |
| Pin 2 (S) | Source terminal | Reference node for gate voltage; tied to system ground or bias reference in most linear regulator and current source topologies. |
| Pin 3 (D) | Drain terminal (tab) | Main current-carrying path; electrically and thermally connected to exposed metal tab for heat dissipation and low-inductance routing. |
| Pin 4 (D) | Drain soldering point | Secondary drain connection for enhanced thermal transfer to PCB; must be soldered to ≥6 cm² copper area per datasheet recommendation. |
Key Features
| Feature | Design Value |
|---|---|
| Depletion-mode operation | Enables fail-safe "always-on" behavior without gate bias, simplifying circuit design in backup power and fault-detection paths. |
| AEC-Q101 qualification | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock per JESD47. |
| VGS(th) band sorting (H6906) | Ensures ±0.1 V tolerance in threshold voltage across reels, improving consistency in analog current mirror and bias generator circuits. |
| dv/dt immunity | 6 kV/µs rating prevents spurious turn-on during high-slew-rate transients in motor commutation and relay driving. |
| Halogen-free & RoHS-compliant | Meets IEC61249-2-21 and EU RoHS Directive 2011/65/EU, supporting environmentally regulated automotive supply chains. |
Applications
| Automotive LED Headlamp Bias | Industrial Current Source Reference |
|---|---|
Use Scenario: Stable bias current generation for high-intensity LED arrays in adaptive front lighting systems (AFS). IC Role / Device Role / Timing Role: Depletion-mode MOSFET acts as constant-current sink with fixed IDSS and minimal external components.

IC Role / Device Role / Timing Role: Functions as temperature-stable current source for sensor excitation and calibration circuitry. Use Value: Delivers 140 mA ±5% across 0–70 °C using VGS(th)-sorted H6906 band and low RDS(on) drift. |
| Ignition Coil Primary Clamp | High-Voltage Bus Protection |
Use Scenario: Snubbing inductive kickback from 12 V automotive ignition coils during switch-off events. IC Role / Device Role / Timing Role: Acts as self-triggered clamp using VBR(DSS) = 200 V and fast dv/dt immunity to absorb energy without external trigger. Use Value: Prevents MOSFET failure by limiting VDS to safe levels during 100+ V/µs transients, validated per ISO 7637-2 pulse 5a. | Use Scenario: Overvoltage protection on 24 V DC power distribution buses in commercial vehicles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar depletion-mode MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BSP149H6327XTSA1 | Same die, different reel marking (H6327); unsorted VGS(th) - typical –1.4 V, ±0.3 V variation. | Less suitable for matched current sources; acceptable for general-purpose clamping where threshold spread is tolerable. | Select H6327 for cost-sensitive non-matched applications; H6906 required for precision biasing. |
| DMN2004LK-7 | 20 V VBR(DSS), 1.2 Ω RDS(on), enhancement-mode - requires active gate drive, no depletion behavior. | Cannot replace in fail-safe or zero-bias circuits; only viable where gate control is available and voltage stress is <20 V. | Not a functional substitute; use only if redesign permits gate driver integration and voltage derating. |
Compared with BSP149H6327XTSA1, the H6906 variant offers tighter VGS(th) control for analog matching, while DMN2004LK-7 lacks depletion-mode operation entirely-making it incompatible for bias-free or fail-safe roles despite lower RDS(on).

FAQ
What does the 'H6906' suffix indicate in BSP149H6906XTSA1?
The H6906 marking identifies the VGS(th) threshold voltage band: devices are sorted to –1.5 V to –1.3 V at ID = 400 µA and VDS = 3 V. This banding ensures tighter matching for analog current sources and bias networks where threshold consistency is critical across multiple units.
Can BSP149H6906XTSA1 be used in enhancement-mode configurations?
No - BSP149 is strictly a depletion-mode device. It conducts at VGS = 0 V and requires negative gate voltage to pinch off. It cannot operate as an enhancement-mode switch without violating its safe operating area; attempting to drive it with positive VGS risks exceeding VGS = ±20 V absolute maximum rating.
Is the SOT-223 package lead-free and RoHS compliant?
Yes - BSP149H6906XTSA1 uses Pb-free lead plating and complies with EU RoHS Directive 2011/65/EU and halogen-free requirements per IEC61249-2-21. The PG-SOT223 package is qualified for reflow soldering per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C.
How does the dv/dt rating of 6 kV/µs impact circuit layout?
This rating means the device resists false turn-on when subjected to rapid voltage transients up to 6 kV/µs across drain-source. To maintain this immunity, minimize parasitic gate loop inductance by placing gate resistor close to the gate pin and avoiding long traces between gate driver and MOSFET, especially in high-noise ignition or motor drive environments.
