Product details

Overview

STB13005-1 from STMicroelectronics is a high-voltage fast-switching NPN power transistor in TO-262 (I2PAK) package, rated for V_CEO = 400 V, I_C = 4 A, P_tot = 75 W at T_c = 25°C, with t_s = 1.5 µs and t_f = 0.2 µs under resistive load switching. It serves as the main switching element in electronic ballasts for fluorescent lighting and offline SMPS.

For engineers reviewing the STB13005-1 datasheet, STB13005-1 pinout, STB13005-1 application, or STB13005-1 equivalent, key selection criteria include its 400 V collector-emitter sustaining voltage, low 0.5 V V_CE(sat) at I_C = 1 A / I_B = 0.2 A, cellular emitter structure enabling wide RBSOA, and pre-selected h_FE groups (A: 15–32, B: 27–45) for consistent gain matching in production.

Technical Context

This device employs high-voltage multi-epitaxial planar technology to achieve fast switching while maintaining robust safe operating area. Its cellular emitter layout and planar edge termination jointly optimize dynamic performance and ruggedness under inductive and resistive loads.

It is designed for hard-switched topologies requiring reliable turn-off at high V_CE, with specified t_s and t_f measured using standardized inductive test circuits (IB1 = –IB2 = 0.4 A, V_CC = 125 V, t_p = 30 µs). The 9 V V_EB0 rating supports stable base drive integrity during transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	400 V - Sustaining voltage with open base; defines maximum off-state blocking capability in SMPS primary switches
I_C	4 A continuous - Maximum DC collector current at T_c = 25°C; sets thermal design baseline for heatsink sizing
P_tot	75 W at T_c = 25°C - Total power dissipation limit; requires active thermal management above ~50°C case temperature
t_s / t_f	1.5 µs / 0.2 µs - Storage and fall times under resistive load; enables >100 kHz switching in ballast designs
V_CE(sat)	0.5 V @ I_C = 1 A, I_B = 0.2 A - Low saturation voltage reduces conduction loss and self-heating in linear/switching regions
h_FE	15–45 (grouped) - Pre-selected DC current gain bins ensure predictable base drive requirements across production lots

Pinout & Package

Package: TO-262 (I2PAK), through-hole, tube packaging (suffix "-1"). Three-terminal power package with isolated mounting flange (collector-connected tab).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitter terminal	Low-impedance current return path; directly connected to PCB ground plane in most SMPS layouts
2 (Collector)	Collector terminal	Internally bonded to metal tab; electrically and thermally coupled to heatsink; must be insulated if heatsink is grounded
3 (Base)	Base control terminal	High-impedance input for current-driven switching; requires external base resistor to limit I_B ≤ 2 A peak

Key Features

Feature	Design Value
Cellular emitter + planar edge termination	Enables simultaneous high-speed switching and wide RBSOA-critical for reliability in repetitive overcurrent events
Low dynamic parameter spread	Ensures consistent t_s, t_f, and V_CE(sat) across manufacturing lots-reduces need for post-production binning
Pre-selected h_FE groups (A/B)	Guarantees matched DC gain within ±15% tolerance-simplifies base drive design for parallel operation or batch production
ECOPACK® lead-free construction	Meets RoHS and JEDEC JESD97 second-level interconnect standards-supports environmentally compliant industrial assembly

Applications

Electronic Ballast

Offline SMPS

Use Scenario: High-frequency AC-to-AC conversion driving 36–40 W fluorescent lamps in commercial lighting fixtures.

IC Role / Device Role / Timing Role: Main switch in half-bridge resonant inverter stage; operates at 25–65 kHz with zero-voltage switching assist.

Use Scenario: Primary-side switch in 60–100 W universal-input flyback converters for industrial power supplies.

IC Role / Device Role / Timing Role: Hard-switched NPN transistor controlling energy transfer from bulk capacitor to transformer primary.

Use Value: 75 W P_tot rating allows full-load operation with modest heatsinking; low V_CE(sat) improves efficiency at 50–75% load.

Inductive Heater Driver

DC Motor Commutation

Use Scenario: Medium-power (≤80 W) induction heating module for small kitchen appliances.

IC Role / Device Role / Timing Role: Switching element in Class-E resonant oscillator driving series-LC tank at 100–200 kHz.

Use Value: Cellular emitter structure maintains stable gain and SOA under high di/dt; 150 °C T_J(max) supports compact enclosure thermal design.

IC Role / Device Role / Timing Role: Low-side switch in H-bridge configuration handling bidirectional current up to 4 A peak.

Use Value: 8 A I_CM peak rating accommodates motor stall currents; 9 V V_EB0 prevents base-emitter breakdown during back-EMF spikes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage NPN power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STB13004-1	V_CEO = 300 V, P_tot = 65 W, t_f = 0.3 µs - lower voltage rating and slower switching	Suitable only for ≤250 V DC bus applications; not recommended for 400 V fluorescent ballasts	Select when cost sensitivity outweighs 100 V headroom requirement and switching frequency remains <50 kHz
BU508A	V_CEO = 1500 V, I_C = 8 A, t_f = 0.5 µs - higher voltage but significantly slower and less gain-stable	Used in CRT flybacks and legacy TV power supplies; lacks pre-selected h_FE grouping	Choose only for ultra-high-voltage legacy replacements where SOA margin is prioritized over switching speed

Compared with STB13004-1 and BU508A, the STB13005-1 uniquely balances 400 V blocking, sub-µs switching, and factory-gain binning-making it optimal for modern electronic ballasts and compact SMPS where thermal density and lot-to-lot consistency are critical.

FAQ

Is the STB13005-1 RoHS-compliant?

Yes. The STB13005-1 is manufactured in an ECOPACK® package with lead-free second-level interconnect, fully compliant with RoHS Directive 2011/65/EU and JEDEC Standard JESD97. The inner box label specifies the lead-free status and soldering profile limits.

What is the thermal resistance R_thJC for the I2PAK package?

The junction-to-case thermal resistance (R_thJC) is 1.67 °C/W, measured from die to the mounting surface of the collector tab. This value assumes full contact between the tab and a flat, smooth, thermally conductive heatsink with appropriate thermal interface material.

Can STB13005-1 be used in parallel configurations?

Yes, but only with matched h_FE groups (A+A or B+B) and individual base resistors. The pre-selected gain bins reduce current imbalance, and the wide RBSOA supports stable sharing under transient overload-however, forced-air cooling is recommended for >2 devices in parallel.

Does the "-1" suffix indicate tape-and-reel packaging?

No. The "-1" suffix denotes tube packaging for through-hole mounting. ST uses "-TR" for tape-and-reel variants. Tube packaging facilitates manual or wave-solder assembly and is standard for high-power discrete transistors like the STB13005 series.
