Product details

Overview

APT13005DT-G1 from Diodes Incorporated is a 450V NPN high-voltage power transistor in TO220AB Type C (TO220-3(2)) non-isolated package, featuring BV_CEO = 450 V, BVCES = 700 V, I_C = 4 A continuous, integrated anti-parallel diode, and anti-saturation logic-designed for low-power AC-DC SMPS in LED lighting and mobile device battery chargers.

For engineers reviewing the APT13005DT-G1 datasheet, APT13005DT-G1 pinout, APT13005DT-G1 application, or APT13005DT-G1 equivalent, key selection criteria include high-voltage blocking capability (700 V BVCES), thermal resistance (R_θJC = 1.67 °C/W), safe operating area robustness, integrated freewheeling diode functionality, and RoHS-compliant green packaging for automotive-qualified designs.

Technical Context

This NPN bipolar junction transistor operates as a primary-side switching element in flyback and forward converters, where its 700 V BVCES rating enables reliable operation under voltage transients and leakage inductance spikes. Its integrated anti-parallel diode eliminates external snubber diode requirements in inductive load switching.

The anti-saturation feature limits V_CE(sat) to ≤0.9 V at I_C = 4 A / I_B = 1 A, reducing conduction loss while maintaining fast turn-off via controlled base drive. Thermal performance is optimized for PCB-mounted heatsinking with R_θJC = 1.67 °C/W in the TO220AB Type C package.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	450 V - Sustains 450 V collector-emitter voltage before breakdown; enables use in 230 VAC input SMPS with margin.
V_CES	700 V - Withstands 700 V with base open; critical for handling voltage spikes in discontinuous conduction mode.
I_C	4 A - Continuous collector current rating; supports up to ~25 W output in compact AC-DC adapters.
R_θJC	1.67 °C/W - Junction-to-case thermal resistance; allows 75 W power dissipation at T_C = 25 °C.
V_CE(sat)	0.9 V @ I_C = 4 A, I_B = 1 A - Low saturation voltage reduces conduction loss and self-heating in high-duty-cycle operation.
f_T	4 MHz - Transition frequency supports switching up to ~100 kHz with adequate gain margin in driver circuits.
h_FE	15–35 @ I_C = 1–2 A - Moderate DC current gain enables stable base-driven operation without excessive drive power.

Pinout & Package

APT13005DT-G1 uses the TO220AB Type C (TO220-3(2)) non-isolated plastic package with matte tin-plated leads, UL 94V-0 molding compound, and 2000 mg typical weight. Mounting tab is electrically connected to collector.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically tied to metal tab; requires insulated mounting hardware when referenced to non-ground potentials.
Base	Control input	Receives current-limited drive signal to switch transistor between cutoff and saturation regions.
Emitter	Power return path	Serves as common reference for load current; connects to ground or low-side return in flyback primary circuits.

Key Features

Feature	Design Value
Integrated anti-parallel diode	Eliminates need for external freewheeling diode in inductive switching applications, reducing BOM count and PCB area.
Anti-saturation logic	Prevents deep saturation, enabling faster turn-off and lower storage time (t_s = 4.0 µs) without external Baker clamp.
700 V BVCES rating	Provides 55% voltage headroom above 450 V V_CEO, improving reliability in high-leakage-inductance transformer designs.
RoHS & Halogen-free compliance	Meets EU RoHS 3 (2015/863/EU) and Diodes' "Green" standard (<900 ppm Br/Cl, <1000 ppm Sb), supporting automotive PPAP submissions.
ESD HBM rating	8 kV human-body-model ESD tolerance simplifies handling and assembly in non-ESD-protected production environments.

Applications

Battery Charger for Smartphones

LED Lighting Power Supply

Use Scenario: Compact wall-adaptor design converting 90–264 VAC to 5 V/2 A USB output.

IC Role / Device Role / Timing Role: Primary-side NPN switch in quasi-resonant flyback topology, operating at 65 kHz with valley-switching control.

Use Value: Integrated anti-parallel diode replaces discrete D1, reducing component count by one; 700 V BVCES prevents failure during line surge events.

Use Scenario: Constant-current driver for 12–24 V LED strings in commercial downlights.

IC Role / Device Role / Timing Role: Main switching transistor in isolated buck-boost converter, delivering 350 mA at 36 V with ±3% regulation.

Use Value: 4 A I_C rating supports 15 W output with margin; R_θJC = 1.67 °C/W enables heatsink-free operation up to 40°C ambient.

DVD/STB Power Supply

Industrial Sensor Interface PSU

Use Scenario: Dual-output (5 V/1 A, 12 V/0.5 A) standby + main SMPS in set-top box.

IC Role / Device Role / Timing Role: High-voltage switch in auxiliary winding-regulated standby circuit, operating continuously at light load.

Use Value: 9 V V_EBO rating ensures stable base-emitter junction behavior during brownout conditions; low V_CE(sat) minimizes no-load power loss.

Use Scenario: 24 VAC-to-12 VDC isolated supply powering analog sensor front-ends in factory automation nodes.

IC Role / Device Role / Timing Role: Primary-side switch in low-noise forward converter with synchronous rectification on secondary side.

Use Value: Anti-saturation design reduces t_s to 4.0 µs, enabling clean turn-off edge and minimizing EMI in noise-sensitive measurement circuits.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
APT13003DT-G1	Lower V_CEO = 400 V, same TO220AB Type C package, I_C = 3 A	Not suitable for 230 VAC mains with high leakage inductance; limited to 12–18 W designs	Select only if system peak V_CE remains below 360 V and thermal budget permits higher R_θJC.
MJD13005G	Same V_CEO/V_CES ratings but TO220AB Type BR (isolated tab), no integrated diode, h_FE min = 8	Requires external freewheeling diode and insulating washer; less compact layout	Choose when isolation between tab and PCB is mandatory, or when discrete diode placement improves thermal management.

Compared with APT13005DT-G1, APT13003DT-G1 trades voltage margin for lower cost in sub-20 W applications, while MJD13005G offers mechanical isolation at the expense of added components and board space-making APT13005DT-G1 optimal for cost-, size-, and reliability-constrained 20–25 W AC-DC systems.

FAQ

Is APT13005DT-G1 still in active production?

No-APT13005DT-G1 is marked obsolete per Diodes' DS36463 Rev. 3-4 (June 2021). However, Aetrix Electronics maintains legacy inventory and supports last-time-buy programs with full traceability, documentation, and extended lifecycle coordination for ongoing production runs.

Can APT13005DT-G1 be used in AEC-Q101 qualified designs?

APT13005DT-G1 itself is not AEC-Q101 certified, but Diodes states that automotive-qualified versions (with PPAP capability and IATF 16949 manufacturing) are available upon request. Customers must contact Diodes directly or through Aetrix to obtain change-controlled automotive-grade variants.

What is the maximum recommended switching frequency for this transistor?

Based on f_T = 4 MHz and measured switching times (t_on = 0.7 µs, t_s = 4.0 µs, t_f = 0.8 µs), the practical upper limit is ~100 kHz in hard-switched topologies. For quasi-resonant or zero-voltage-switching designs, operation up to 130 kHz is feasible with proper gate drive optimization.

Does the integrated anti-parallel diode have specified reverse recovery characteristics?

No reverse recovery time (t_rr) or Q_rr is specified in the datasheet. The diode is intended for low-frequency freewheeling (≤100 kHz); for high-frequency or high-dI/dt applications, external ultrafast diodes may be required to avoid excessive loss or oscillation.
