Product details

Overview

BSS119NH7796 from Infineon Technologies is an N-channel enhancement-mode logic-level MOSFET in PG-SOT23 package, rated for 100 V V_DS, 6 Ω R_DS(on) at V_GS = 10 V, and 0.19 A continuous drain current. It features avalanche rating, AEC-Q101 qualification, and 100% lead-free RoHS/halogen-free construction - used in automotive body electronics, LED drivers, and low-power load switching.

For engineers reviewing the BSS119NH7796 datasheet, BSS119NH7796 pinout, BSS119NH7796 application, or BSS119NH7796 equivalent, key selection criteria include logic-level gate drive compatibility (4.5 V), thermal resistance (250 K/W on minimal FR4 footprint), and reverse diode performance (V_SD = 0.8–1.1 V at 0.19 A).

Technical Context

This OptiMOS™ small-signal transistor operates in enhancement mode with a gate threshold voltage of 1.3–2.3 V and supports logic-level control down to 4.5 V. Its 100 V breakdown voltage and 2.0 mJ single-pulse avalanche energy enable robust operation in inductive load switching.

Dynamic characteristics include C_iss = 15.7–20.9 pF, t_r = 3.3 ns, and t_f = 18.8 ns, supporting fast switching in space-constrained DC-DC and signal routing applications. The integrated body diode exhibits t_rr = 12 ns and Q_rr = 5 nC under specified conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	100 V - supports 24 V/48 V automotive and industrial bus systems with margin
R_DS(on) @ V_GS=10 V	6 Ω max - enables <1.2 W conduction loss at 0.19 A in compact SOT23
R_DS(on) @ V_GS=4.5 V	10 Ω max - ensures reliable turn-on with standard 3.3 V/5 V logic outputs
I_D continuous	0.19 A @ T_A=25 °C - suitable for low-current sensor biasing and LED segment control
E_AS	2.0 mJ - withstands inductive kickback in relay/actuator driver circuits
Q_g total	0.6 nC - minimizes gate drive power and enables efficient PWM at >1 MHz
t_rr	12 ns - reduces switching losses and EMI in high-frequency load switching

Pinout & Package

Package: PG-SOT23 (standard 3-pin surface-mount, JEDEC TO-236AB outline). Pin assignment verified per Infineon BSS119N datasheet Rev 2.1.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2004LK-7	R_DS(on) = 4.5 Ω @ 4.5 V; higher I_D = 0.3 A; same SOT23 package	Higher current handling but no AEC-Q101 qualification	Preferred for non-automotive consumer power management where qualification is not required
FDV303N	R_DS(on) = 3.1 Ω @ 4.5 V; lower V_DS = 20 V; same footprint	Limited to ≤24 V systems; unsuitable for 48 V or load-dump environments	Optimal for cost-sensitive 3.3 V/5 V logic-controlled switches below 20 V bus

Compared with DMN2004LK-7 and FDV303N, BSS119NH7796 uniquely combines AEC-Q101 qualification, 100 V rating, and 4.5 V logic compatibility - making it the only choice for automotive-grade 24–48 V load switching where reliability and transient robustness are mandatory.

FAQ

Is BSS119NH7796 pin-compatible with standard SOT23 N-channel MOSFETs?

Yes - BSS119NH7796 uses the standard PG-SOT23 (TO-236AB) package with Drain-Source-Gate pinout (1-2-3), matching industry-standard SOT23 footprints. Layout compatibility is confirmed by Infineon's mechanical drawings and verified on 40 mm² FR4 PCBs with 1 mm traces.

What is the maximum junction temperature and how does it affect continuous current rating?

The absolute maximum junction temperature is 150 °C. At T_A = 70 °C, the continuous drain current derates to 0.15 A due to thermal resistance of 250 K/W on minimal FR4. Derating follows the published I_D vs. T_A curve (Rev 2.1, page 4), with full 0.19 A only guaranteed at 25 °C ambient.

Does BSS119NH7796 include an integrated body diode, and what are its key parameters?

Yes - it integrates a monolithic body diode with I_S = 0.19 A continuous, V_SD = 0.8–1.1 V at 0.19 A and 25 °C, t_rr = 12 ns, and Q_rr = 5 nC. These values are measured under V_R = 50 V, I_F = 0.19 A, and di_F/dt = 100 A/µs per datasheet page 3.

Can BSS119NH7796 be used in linear (analog) operation, and what limits apply?

It is not optimized for linear mode; safe operating area (SOA) curves (page 4) show limited DC capability - e.g., 0.1 A at 50 V requires active heatsinking. Linear use is restricted to brief pulses within the single-pulse SOA boundary; sustained analog operation risks thermal runaway due to positive tempco of R_DS(on).
