Product details

Overview

STN9360 from STMicroelectronics is a high-voltage fast-switching PNP power transistor in SOT-223 package, rated for V_CEO = −600 V, I_C = −0.5 A, and P_TOT = 1.6 W at T_a = 25 °C, with t_r = 45 ns and t_f = 160 ns under resistive load switching. It is designed for lighting ballasts and low-cost switch-mode power supplies operating up to 150 °C junction temperature.

For engineers reviewing the STN9360 datasheet, STN9360 pinout, STN9360 application, or STN9360 equivalent, key selection criteria include its −600 V blocking capability, cellular emitter structure enabling wide RBSOA, fast turn-off performance (t_f = 160 ns), and SOT-223 thermal resistance of 78 °C/W on 1 cm² PCB area.

Technical Context

This device employs high-voltage multi-epitaxial planar technology with planar edge termination to achieve stable breakdown and fast switching. Its cellular emitter design balances high voltage hold-off (V_CE(sus) = −600 V at I_C = −10 mA) and robust safe operating area under pulse conditions.

The transistor operates as a grounded-emitter, common-base configured switch in flyback and resonant lighting topologies. Base drive requirements are defined by V_BE(sat) = −1 V at I_C = −100 mA / I_B = −10 mA and h_FE = 120–200 across I_C = −1 to −20 mA at V_CE = −5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−600 V - supports primary-side switching in 230 VAC offline SMPS with ≥2× safety margin
I_C	−0.5 A continuous - suitable for <15 W lighting drivers and auxiliary supplies
t_f	160 ns - enables >100 kHz operation with low switching loss in hard-switched topologies
R_thJA	78 °C/W - requires minimal copper area (1 cm²) for thermal management in cost-sensitive designs
h_FE	120–200 @ I_C = −10 mA - allows direct TTL-compatible base drive without amplification
V_CE(sat)	−0.5 V @ I_C = −100 mA - limits conduction loss to <50 mW at rated current

Pinout & Package

STN9360 is housed in a standard SOT-223 package with exposed collector tab for thermal conduction and mechanical anchoring. Pin 1 is Emitter, Pin 2 is Base, Pin 3 is Collector (tab), and Pin 4 is Collector (second lead). The package complies with ECOPACK® environmental specifications.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current exit path for PNP operation	Connected to input rail or switched node; must handle full load current and reverse recovery stress
Pin 2 (Base)	Control terminal for minority carrier injection	Driven negative relative to emitter; requires −10 mA for full saturation at −100 mA collector current
Pin 3 (Collector, tab)	Main high-voltage output terminal	Electrically and thermally connected to PCB copper pour; provides primary heat dissipation path
Pin 4 (Collector, lead)	Secondary collector connection	Reduces lead inductance and improves current sharing during fast switching transitions

Key Features

Feature	Design Value
Cellular emitter structure	Enables simultaneous optimization of switching speed and ruggedness-supports wide RBSOA without sacrificing t_f
Planar edge termination	Ensures stable −600 V breakdown across temperature and process variation, critical for lighting surge immunity
High-voltage multi-epitaxial planar process	Delivers consistent V_CE(sus) and low leakage (I_CES ≤ −10 μA) after 1000-hour life testing
SOT-223 thermal design	Exposed collector tab achieves 78 °C/W R_thJA on minimal 1 cm² PCB copper-reduces need for heatsinks in space-constrained fixtures

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage PNP switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STN9360D	Same die, enhanced ECOPACK®2 compliance; identical electrical specs and pinout	No functional difference; qualified for stricter RoHS and halogen-free requirements	Select when regulatory compliance (e.g., China RoHS II, JEITA EG02) is mandatory
MJD44H11T4	Higher I_C = −8 A but slower t_f = 1.2 μs; V_CEO = −80 V only	Not suitable for 230 VAC primary-side switching; limited to low-voltage DC-DC converters	Only viable if system voltage ≤ 100 V and higher current handling is required

Compared with STN9360D, the base part offers identical performance with standard ECOPACK®; versus MJD44H11T4, it trades current capacity for high-voltage robustness and speed-making it uniquely suited for cost-sensitive 230 VAC lighting and SMPS primary switches.

FAQ

What is the maximum recommended gate/base drive current for reliable switching?

The STN9360 requires −10 mA base current for full saturation at −100 mA collector current, with peak base current rated at −0.5 A for pulses <5 ms. Exceeding −0.5 A risks metallization damage. For repetitive operation, sustained base current should remain ≤ −0.25 A per absolute maximum ratings table.

Can STN9360 be used in avalanche mode?

No. The STN9360 is not rated for repetitive avalanche operation. Its safe operating area curves assume non-avalanche switching with external snubbers or clamping. The −600 V rating applies only under specified test conditions (IB = 0); operation beyond V_CE(sus) risks irreversible degradation.

Is the SOT-223 package lead-free and RoHS compliant?

Yes. The STN9360 is manufactured in an ECOPACK®-compliant SOT-223 package, meeting RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1. Full compliance documentation is available via ST's quality portal using device marking "N9360".

How does thermal performance change when mounted on 2 cm² vs. 1 cm² copper?

Mounting on 2 cm² copper reduces R_thJA from 78 °C/W to approximately 52 °C/W, improving power handling by ~40%. This allows continuous I_C up to −0.7 A at T_a = 50 °C, provided solder joint integrity and board stack-up support uniform heat spreading.
