Product details
Overview
APT13005SU-G1 from Diodes Incorporated is a 450V NPN high-voltage power transistor in TO126 package, rated for 3.2A continuous collector current, 700V collector-emitter breakdown (BVCES), and 9V emitter-base breakdown. It serves as a switching element in low-power AC-DC SMPS for mobile phone chargers, LED lighting, and STB power supplies.
For engineers reviewing the APT13005SU-G1 datasheet, APT13005SU-G1 pinout, APT13005SU-G1 application, or APT13005SU-G1 equivalent, key selection criteria include VCEO/VCES ratings, hFE consistency at IC = 1–3A, VCE(sat) under defined IB drive, thermal resistance (RθJC = 6.25°C/W), and TO126 mechanical compatibility with heatsink mounting.
Technical Context
This NPN bipolar junction transistor operates in linear or saturated switching mode with guaranteed BVCEO ≥ 450V and BVCES ≥ 700V, enabling robust operation in flyback and RCD-clamped topologies. Its DC current gain (hFE) ranges from 20 to 35 at IC = 1A–2A with VCE = 5V, supporting stable base-driven control.
VCE(sat) remains ≤ 1.0V up to IC = 3A with IB = 0.75A, minimizing conduction loss in 60–100kHz SMPS designs. Transition frequency fT = 4MHz and COB = 35pF support predictable turn-on/turn-off timing (ton = 0.7µs, ts = 4.5µs, tf = 0.8µs) under resistive load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 450V - Maximum safe collector-emitter voltage under open-base condition; defines primary isolation rating in offline SMPS. |
| BVCES | 700V - Collector-emitter breakdown with base shorted to emitter; supports voltage margin during transient clamping. |
| IC (cont.) | 3.2A - Continuous collector current limit at TC = 25°C; sets maximum output power capability in TO126 package. |
| VCE(sat) | ≤1.0V @ IC = 3A, IB = 0.75A - Low saturation voltage reduces conduction loss and thermal stress in high-duty-cycle operation. |
| RθJC | 6.25°C/W - Junction-to-case thermal resistance; determines heatsink sizing requirement for 20W PD at TC = 25°C. |
| hFE | 20–35 @ IC = 1–2A - Sufficient DC gain for direct base drive without complex amplification; enables simple gate driver interface. |
| fT | 4MHz - Transition frequency limiting usable switching speed; suitable for <100kHz SMPS with controlled rise/fall times. |
Pinout & Package
APT13005SU-G1 uses the TO126 molded plastic package with matte tin-plated terminals, UL 94V-0 flammability rating, and 400mg typical weight. Pin configuration is fixed: Emitter (E), Collector (C), Base (B) - left-to-right when viewing front face with tab down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current return path to ground/reference rail | Low-impedance connection point; must be routed with minimal inductance in high-di/dt SMPS layouts. |
| C (Collector) | Main high-voltage current input/output node | Connected to transformer primary or RCD clamp; requires >2.5mm creepage clearance per IEC 62368-1. |
| B (Base) | Control terminal for forward-biased injection | Driven by optocoupler or controller IC; requires series resistor to limit IB peak and prevent overdrive. |
Key Features
| Feature | Design Value |
|---|---|
| High voltage blocking | Guaranteed BVCEO ≥ 450V and BVCES ≥ 700V - enables use in universal-input (85–265VAC) flyback converters without derating. |
| Lead-free & green compliance | RoHS 3 compliant, halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - meets automotive and industrial environmental mandates. |
| Thermal performance | RθJC = 6.25°C/W in TO126 - allows 20W dissipation with modest heatsinking, reducing system size vs. TO220 alternatives. |
| Robust ESD tolerance | HBM rating of 8kV - improves handling reliability during PCB assembly and rework without additional protection circuitry. |
Applications
| Mobile Phone Charger | DVD/STB Power Supply |

FAQ
Is APT13005SU-G1 still in active production?
No - APT13005SU-G1 is officially marked obsolete by Diodes Incorporated (DS42598 Rev. 1-4, February 2020). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for last-time buys and design migration paths.
What is the pin configuration for APT13005SU-G1 in TO126 package?
Viewing the front face with the mounting tab oriented downward, the pin order from left to right is Emitter (E), Collector (C), Base (B). The collector is internally connected to the metal tab, requiring electrical isolation when mounted to a heatsink.
Can APT13005SU-G1 replace a MOSFET in an existing flyback design?
It can functionally replace low-speed, low-frequency bipolar switches but not logic-level or high-frequency MOSFETs. Its 4MHz fT and µs-scale switching times suit ≤100kHz designs; gate drive must be converted to base-current drive with appropriate resistor sizing and saturation monitoring.
Does APT13005SU-G1 meet AEC-Q101 for automotive use?
No - the datasheet explicitly states that AEC-Q101 qualification applies only to parts "contacted separately" and does not extend to APT13005SU-G1. This device is intended for industrial and consumer power applications, not automotive-grade systems.
