Product details
Overview
APT13005DI-G1 from Diodes Incorporated is an obsolete 450V NPN high-voltage power transistor with integrated anti-parallel diode and anti-saturation feature, rated for 4A continuous collector current, 700V collector-emitter breakdown (BVCES), and housed in ITO220AB TYPE BR (TO220F) package. It serves as a switching element in low-power AC-DC SMPS for mobile phone chargers and LED lighting.
For engineers reviewing the APT13005DI-G1 datasheet, APT13005DI-G1 pinout, APT13005DI-G1 application, or APT13005DI-G1 equivalent, key selection factors include its 450V VCEO rating, integrated freewheeling diode, TO220F isolation, 28W thermal dissipation at TC=25°C, and BVEBO >9V for base protection in high-voltage flyback designs.
Technical Context
This device is a silicon NPN bipolar junction transistor optimized for high-voltage switching in offline flyback and forward converters. Its anti-saturation design limits VCE(sat) to ≤0.9V at IC=4A/IB=1A, while the integrated anti-parallel diode enables self-contained freewheeling without external components.
The ITO220AB TYPE BR (TO220F) package provides electrical isolation between collector and mounting tab, supporting safe operation in grounded-collector topologies. Thermal resistance RθJC is 4.5°C/W, enabling stable operation up to TJ=150°C when properly heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 450V - Maximum collector-emitter voltage before avalanche in open-base condition; defines safe operating ceiling in flyback primary switches. |
| BVCES | 700V - Collector-emitter breakdown with base shorted to emitter; supports robust surge tolerance during transient overvoltage events. |
| IC | 4A - Continuous DC collector current; sets maximum average power handling in linear or PWM-switched operation. |
| VCE(sat) | 0.9V @ IC=4A, IB=1A - Low saturation voltage reduces conduction loss and heat generation in high-duty-cycle applications. |
| RθJC | 4.5°C/W - Junction-to-case thermal resistance; determines minimum heatsink requirement for 28W power dissipation at TC=25°C. |
| hFE | 15–35 @ IC=1–2A - Moderate DC current gain range; supports direct base drive without complex amplification in cost-sensitive SMPS. |
| VEBO | 9V - Emitter-base reverse breakdown voltage; protects base-emitter junction against negative transients in inductive switching. |
Pinout & Package
APT13005DI-G1 uses the ITO220AB TYPE BR (TO220F) package, featuring electrically isolated collector tab for safe mounting to heatsinks without additional insulation. The case is molded plastic (UL 94V-0), with matte tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current sink terminal | Connected to ground or low-side return path; carries full load current and defines reference for base drive. |
| C (Collector) | High-voltage switch node | Electrically isolated tab in TO220F package; connects to primary winding of flyback transformer or DC bus rail. |
| B (Base) | Control input | Receives current-limited drive signal; requires ≥0.2A peak for full saturation at IC=1A, per datasheet test conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated anti-parallel diode | Eliminates need for external freewheeling diode in single-transistor flyback topologies, reducing BOM count and PCB area. |
| Anti-saturation design | Maintains low VCE(sat) under high-current switching, minimizing conduction losses and thermal stress during sustained on-time. |
| Isolated TO220F package | Enables direct mechanical mounting to grounded heatsinks without insulating washers, simplifying thermal management in compact AC-DC adapters. |
| RoHS-compliant & halogen-free | Meets EU RoHS 3 (2015/863/EU) and green compound requirements (<900ppm Br/Cl, <1000ppm Sb), supporting automotive and consumer compliance programs. |
Applications
| Mobile Phone Charger | DVD/STB Power Supply |

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 |
|---|---|---|---|
| APT13003DI-G1 | Lower VCEO (400V) and IC (3A); same TO220F package and integrated diode. | Suitable only for ≤100VDC bus or lower-power flybacks where 450V margin is not required. | Select when system input voltage is limited to 230VAC nominal with low surge exposure. |
| BU508AF | Higher VCEO (1000V), no integrated diode, TO3P package, higher RθJC (2.5°C/W). | Requires external freewheeling diode but supports higher-energy snubbers and wider input ranges. | Choose for 380VDC PFC front-end stages or industrial 3-phase rectified inputs. |
Compared with APT13005DI-G1, APT13003DI-G1 trades voltage headroom for lower cost in entry-level chargers, while BU508AF offers extended voltage capability at the expense of board space and discrete component count-making each suitable for distinct input-range and safety-margin requirements.

FAQ
Is APT13005DI-G1 still in active production?
No, APT13005DI-G1 is officially marked obsolete by Diodes Incorporated as of June 2021. However, Aetrix Electronics maintains legacy inventory with full traceability and offers controlled distribution for ongoing production runs and repair programs.
What is the difference between APT13005DI-G1 and APT13005DT-G1?
APT13005DI-G1 uses the ITO220AB TYPE BR (TO220F) package with electrically isolated collector tab, while APT13005DT-G1 uses the non-isolated TO220AB Type C (TO220-3(2)) package. This affects heatsink mounting requirements and creepage/clearance in high-voltage designs.
Can APT13005DI-G1 replace BU2508DF in a 12W charger design?
Only with circuit validation: BU2508DF has higher VCEO (800V) and different hFE profile. APT13005DI-G1's 450V rating may be insufficient for 230VAC + surge conditions unless derated per IEC 61000-4-5, and its integrated diode alters snubber design.
Does APT13005DI-G1 meet AEC-Q101 for automotive use?
No-though Diodes offers AEC-Q101 qualified variants in the same family (e.g., APT13005DQ-G1), the APT13005DI-G1 part number is not certified. Automotive designs require explicit PPAP documentation and IATF 16949 manufacturing evidence, which this variant lacks.
