Product details

Overview

ST13007D from STMicroelectronics is a high-voltage fast-switching NPN power transistor with integrated freewheeling diode, rated for V_CEO = 400 V, I_C = 8 A, P_tot = 80 W at T_c ≤ 25 °C, and characterized up to 125 °C junction temperature. It targets electronic transformers for halogen lamps and switch-mode power supplies requiring robust RBSOA and tight dynamic parameter spread.

For engineers reviewing the ST13007D datasheet, ST13007D pinout, ST13007D application, or ST13007D equivalent, key selection criteria include its 400 V sustaining voltage, 1.7 µs storage time at 25 °C, 2.5 V diode forward voltage at 3 A, 18–40 h_FE range at 2 A/5 V, and TO-220 package thermal resistance of 1.56 °C/W (junction-to-case).

Technical Context

This device employs Multi Epitaxial Planar technology with a Cellular Emitter structure to achieve very high switching speed and low spread in dynamic parameters. Its integrated freewheeling diode enables self-contained inductive load handling without external clamping components.

Rated for operation up to 150 °C junction temperature and fully characterized at 125 °C, it delivers stable gain preselection (h_FE = 18–40), tight storage time (1.7–2.3 µs), and low leakage (ICES = 10 µA at 700 V, 25 °C) - critical for reliable SMPS and transformer driver designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	400 V - Sustaining voltage under open-base condition; defines maximum safe collector-emitter blocking capability in switching applications.
I_C	8 A continuous - Maximum DC collector current at T_c ≤ 25 °C; supports high-power halogen lamp drivers and mid-range SMPS output stages.
h_FE	18–40 at I_C = 2 A, V_CE = 5 V - Preselected DC current gain range ensures consistent base drive design across production lots.
t_s	1.7–2.3 µs at T_c = 25–125 °C - Storage time under inductive load (V_CL = 250 V, L = 200 µH); directly impacts minimum off-time and switching frequency limit.
V_f	2.5 V at I_C = 3 A - Forward voltage of integrated freewheeling diode; reduces component count and PCB area in flyback/forward converter snubberless topologies.
R_thj-case	1.56 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing for 80 W dissipation at case temperature ≤ 25 °C.

Pinout & Package

ST13007D is housed in a standard TO-220 package (3-pin, straight lead, insulated tab), with pin 1 = emitter, pin 2 = base, pin 3 = collector. The metal tab is electrically connected to the collector and must be isolated from heatsink unless system grounding permits.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current return path for collector current	Low-inductance emitter connection essential for minimizing switching oscillation in high-dI/dt applications.
Pin 2 (Base)	Control terminal for minority carrier injection	Requires precise current-limited drive (I_B ≤ 4 A peak) to ensure saturation without overdrive-induced storage delay.
Pin 3 (Collector)	Main high-voltage current path and thermal interface	Collector-connected tab provides primary heat conduction path; requires insulating washer if heatsink is grounded.

Key Features

Feature	Design Value
Integrated freewheeling diode	Eliminates need for external clamp diode in inductive switching circuits, reducing BOM count and layout complexity.
Tight storage time range (1.7–2.3 µs)	Enables predictable timing control in fixed-frequency SMPS, minimizing risk of cross-conduction in half-bridge configurations.
Full characterization at 125 °C	Guarantees parametric stability under sustained high-temperature operation typical in enclosed lighting and power adapter enclosures.
Large RBSOA (Reverse Biased Safe Operating Area)	Supports reliable operation during transient overvoltage events in transformer-coupled topologies without secondary snubbers.
Low lot-to-lot parameter spread	Reduces need for post-production binning or adaptive base drive tuning in high-volume manufacturing.

Applications

Halogen Lamp Electronic Transformers

Offline Switch-Mode Power Supplies

Use Scenario: High-frequency AC generation (20–50 kHz) to drive 12 V/20–50 W halogen lamps via step-down ferrite transformer.

IC Role / Device Role / Timing Role: Main switching transistor in push-pull or half-bridge topology; handles 400 V blocking and 8 A peak current during each half-cycle.

Use Value: Integrated diode replaces external recovery diode; tight t_s ensures clean dead-time control and prevents transformer core saturation.

Use Scenario: Primary-side switch in 30–100 W offline flyback converters powering LED drivers or industrial controls.

IC Role / Device Role / Timing Role: High-voltage NPN switch operating in discontinuous conduction mode (DCM) with V_CE stress up to 400 V during MOSFET-replacement retrofit designs.

Use Value: 150 °C max junction rating and RBSOA compliance allow reliable operation without derating in compact, thermally constrained enclosures.

DC-DC Converter Output Stages

Industrial Motor Control Drivers

Use Scenario: Low-side switch in isolated 24–48 V input DC-DC converters delivering 5–12 V at up to 6 A for PLC I/O modules.

IC Role / Device Role / Timing Role: Fast-switching NPN in synchronous rectifier-assisted topology; leverages low V_CE(sat) (≤1.5 V at 5 A) to minimize conduction loss.

Use Value: Tight h_FE range (18–40) simplifies base resistor selection across production batches, improving yield in automated assembly.

Use Scenario: Gate driver stage or auxiliary power switch in 24–48 V brushed DC motor controllers for HVAC actuators and valve positioners.

IC Role / Device Role / Timing Role: High-current, high-voltage switch controlling motor winding current with integrated diode for back-EMF recirculation.

Use Value: 16 A peak collector current rating and 120 W power capability support short-duration stall conditions without thermal runaway.

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
ST13005D	V_CEO = 400 V, I_C = 5 A, P_tot = 50 W - lower current/power rating, identical pinout and gain range.	Suitable only for ≤30 W halogen transformers or low-power SMPS where peak current stays below 5 A.	Select when thermal budget or cost constraints require reduced die size and lower dissipation capability.
BU508AF	V_CEO = 1500 V, I_C = 10 A, no integrated diode - higher voltage rating but requires external freewheeling diode.	Better suited for high-input-voltage (>600 VAC) SMPS or CRT flyback applications where 700 V blocking is mandatory.	Choose when system-level voltage transients exceed 400 V or when discrete diode placement improves thermal management.

Compared with ST13005D, ST13007D delivers +60% continuous current and +60% power handling in the same TO-220 footprint; versus BU508AF, it trades 1100 V headroom for integrated diode functionality and tighter dynamic parameter control - optimizing for cost-sensitive, thermally constrained 400 V applications.

FAQ

Is the ST13007D pin-compatible with other TO-220 NPN transistors like the 2N3055?

No. While both use TO-220 packages, ST13007D has emitter-base-collector pinout (E-B-C), whereas 2N3055 uses emitter-collector-base (E-C-B). Incorrect insertion risks immediate failure. Always verify pin assignment using the official STMicroelectronics mechanical drawing (P011CI) before PCB layout or assembly.

Can the integrated diode be used as the main freewheeling path in a flyback converter?

Yes - the integrated diode is rated for 3 A forward current with V_f = 2.5 V and is fully characterized for inductive switching. It is intended for this purpose, eliminating external diode requirements in space-constrained flyback designs operating below 5 A peak secondary current.

What is the maximum allowable case temperature for continuous 8 A operation?

At I_C = 8 A and P_tot = 80 W, the maximum case temperature is 25 °C (per Absolute Maximum Ratings). To sustain 8 A continuously at higher ambient temperatures, active cooling or derating per the published derating curve (Figure 3 in datasheet) is required - e.g., 40 W at T_c = 100 °C.

Does ST13007D support base-emitter reverse biasing for faster turn-off?

Yes - the datasheet specifies V_EB0 = 9 V and characterizes switching with V_BE(off) = –5 V. Applying –5 V during turn-off reduces storage time by extracting minority carriers more rapidly, improving efficiency in high-frequency (>20 kHz) applications.
