Product details
Overview
BSS169L6327HTSA1 from Infineon Technologies is an N-channel depletion-mode SIPMOS® small-signal transistor in PG-SOT-23 package, rated for 100 V VDS, 12 Ω max RDS(on) at VGS = 0 V, and 90 mA IDSS; used in voltage-controlled constant-current sources and high-voltage level-shift circuits requiring dv/dt immunity.
For engineers reviewing the BSS169L6327HTSA1 datasheet, BSS169L6327HTSA1 pinout, BSS169L6327HTSA1 application, or BSS169L6327HTSA1 equivalent, key selection criteria include depletion-mode gate threshold (–2.2 V typ), 6 kV/µs dv/dt rating, VGS(th) banding (L-band: –2.3 to –2.1 V), and integrated body diode with 25.6 ns trr.
Technical Context
This device operates as a normally-on switch requiring negative gate bias to turn off, enabling fail-safe operation in power sequencing and analog bias networks. Its depletion-mode behavior, combined with low gate charge (Qg = 2.1–2.8 nC) and 51–68 pF Ciss, supports fast switching in low-power linear and switching applications up to 100 V.
The integrated body diode exhibits 0.79–1.2 V VSD at 0.17 A and 20.5–25.6 ns reverse recovery time, making it suitable for synchronous rectification and flyback snubber paths where controlled reverse conduction is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - maximum blocking voltage before avalanche; defines safe operating range in high-side bias and level-shift topologies |
| RDS(on) max | 12 Ω at VGS = 0 V - sets on-state power loss and current capability in constant-current source designs |
| IDSS min | 90 mA - guaranteed minimum drain current at zero gate bias; critical for setting reference currents without external bias |
| VGS(th) | –2.2 V typical (L-band: –2.3 to –2.1 V) - precise negative threshold enables predictable turn-off voltage in analog control loops |
| dv/dt rating | 6 kV/µs - ensures immunity to parasitic turn-on in high-dv/dt environments like relay drivers and motor commutation circuits |
| trr | 20.5–25.6 ns - enables efficient reverse recovery in low-frequency flyback and clamp circuits with minimal switching loss |
| Qg | 2.1–2.8 nC - determines gate drive energy requirement and switching speed in PWM-controlled bias networks |
Pinout & Package
Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, 3-pin plastic case with standard footprint per Infineon Rev. 1.6 drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Drain) | High-voltage current output terminal | Connected to load or supply rail; handles full 100 V blocking and 0.17 A continuous current |
| 2 (Gate) | Depletion-mode control input | Receives negative bias (≤ –2.1 V) to reduce ID; zero-bias default state enables fail-safe "always-on" behavior |
| 3 (Source) | Reference node and body diode anode | Serves as common return path; internal diode cathode connects to drain, enabling bidirectional current flow in clamp configurations |
Key Features
| Feature | Design Value |
|---|---|
| Depletion-mode operation | Guarantees conduction at VGS = 0 V, eliminating need for active gate bias in standby or fault-tolerant circuits |
| VGS(th) band sorting (L-band) | Enables tighter current matching across production lots for precision analog current sources and matched-pair bias networks |
| dv/dt immunity (6 kV/µs) | Prevents false triggering during fast transients in relay coil drivers, solenoid controls, and industrial I/O protection stages |
| Integrated body diode | Supports bidirectional current handling without external diode; optimized for 25.6 ns trr and 0.79 V VSD at 0.17 A |
| Pb-free & RoHS-compliant plating | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); suitable for lead-free reflow and high-reliability industrial assembly |
Applications
| Constant-Current Bias Source | High-Voltage Level Shifter |
|---|---|
Use Scenario: Generating stable 90–100 mA reference current for op-amp biasing, LED driver references, or sensor excitation in 24–48 V industrial systems. IC Role / Device Role / Timing Role: Depletion-mode transistor acting as self-biased current sink with no external gate drive required. Use Value: Eliminates precision resistor and voltage reference; leverages guaranteed IDSS,min = 90 mA and tight VGS(th) banding for ±5% current tolerance. | Use Scenario: Translating logic-level signals to 100 V domains in PLC output modules, solid-state relays, and motor phase control. IC Role / Device Role / Timing Role: High-side level-shifting switch with inherent dv/dt immunity preventing spurious turn-on during bus transients. Use Value: 6 kV/µs rating and 100 V VDS enable direct interface to 48 V/72 V DC buses without additional snubbing or isolation. |
| Failsafe Power Sequencing | Analog Clamp Circuit |
Use Scenario: Enabling automatic power-up of auxiliary rails when main supply reaches regulation, e.g., in telecom power management and FPGA configuration sequencers. IC Role / Device Role / Timing Role: Normally-on switch that conducts until gate is actively pulled negative by supervisor IC or microcontroller. Use Value: Inherent fail-safe behavior ensures default power delivery; L-band VGS(th) allows predictable turn-off timing with standard logic-level drivers. | Use Scenario: Clamping inductive kickback from solenoids, relays, or stepper motor windings in automotive body electronics and industrial actuators. IC Role / Device Role / Timing Role: Bidirectional clamp using integrated body diode and controlled RDS(on) to limit voltage overshoot. Use Value: 25.6 ns trr and 12 Ω RDS(on) provide fast, low-loss clamping with <1.2 V forward drop and minimal ringback. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar depletion-mode MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LK-7 | VDS = 20 V, RDS(on) = 3.5 Ω @ VGS = 0 V, IDSS = 200 mA - lower voltage, higher current, no dv/dt rating | Not suitable for >24 V level shifting or 100 V clamp circuits; limited to low-voltage bias and signal switching | Select only for sub-24 V systems requiring higher IDSS and lower RDS(on) |
| BSS138W-7-F | VDS = 50 V, RDS(on) = 3.5 Ω @ VGS = 0 V, IDSS = 100 mA - medium voltage, no dv/dt spec, different VGS(th) distribution | Lacks 6 kV/µs immunity; unsuitable for high-dv/dt relay/solenoid drivers; requires gate pull-down redesign | Choose only when dv/dt immunity is not required and 50 V blocking suffices |
Compared with DMN2004LK-7 and BSS138W-7-F, BSS169L6327HTSA1 uniquely delivers 100 V blocking, 6 kV/µs dv/dt immunity, and factory-sorted VGS(th) bands-making it irreplaceable in industrial-level shifters and failsafe bias networks where voltage margin and transient robustness are non-negotiable.

FAQ
What is the gate threshold voltage range for BSS169L6327HTSA1?
The BSS169L6327HTSA1 is sorted into VGS(th) bands per reel label; the L-band specifies –2.3 V to –2.1 V at VDS = 3 V and ID = 50 µA. This banding is confirmed in Infineon's Rev. 1.6 datasheet page 2, and each reel contains only transistors from one band.
Does BSS169L6327HTSA1 have a built-in body diode?
Yes, it integrates a monolithic body diode with 0.79–1.2 V forward voltage at 0.17 A and 20.5–25.6 ns reverse recovery time. The diode anode connects to the source pin and cathode to the drain, enabling bidirectional current flow in clamp and freewheeling applications.
Can BSS169L6327HTSA1 be used in place of an enhancement-mode MOSFET?
No-it is a depletion-mode device that conducts at VGS = 0 V and requires negative gate bias to turn off. Substituting it for an enhancement-mode MOSFET would invert logic behavior and risk unintended conduction unless gate drive circuitry is redesigned for negative bias control.
Is the PG-SOT-23 package compatible with standard SMT reflow profiles?
Yes-the PG-SOT-23 package meets IPC-J-STD-020 MSL1 classification and is qualified for lead-free reflow with peak temperatures up to 260 °C. Thermal resistance RthJA is 350 K/W on minimal footprint, confirming suitability for standard PCB layouts and automated assembly.
