Product details
Overview
APT13005STF-G1 from Diodes Incorporated is a 450V NPN high-voltage power transistor in TO-126 package, rated for 3.2A continuous collector current, 700V collector-emitter breakdown (BVCES), and 9V emitter-base breakdown (BVEBO); used in low-power AC-DC SMPS for mobile phone chargers and LED lighting.
For engineers reviewing the APT13005STF-G1 datasheet, APT13005STF-G1 pinout, APT13005STF-G1 application, or APT13005STF-G1 equivalent, key selection criteria include safe operating area at 125°C, VCE(sat) ≤ 1.0V at IC = 3A/IB = 0.75A, hFE ≥ 20 at IC = 1A, and RoHS-compliant lead-free finish with UL 94V-0 molding compound.
Technical Context
This NPN bipolar junction transistor operates as a switching element in offline flyback and buck-derived topologies, supporting DC blocking and unidirectional current control with base-driven turn-on/turn-off. Its 700V BVCES rating enables robust operation under transient overvoltage conditions common in universal-input AC-DC converters.
Thermal performance is defined by RθJC = 6.25°C/W (TO-126), enabling 20W dissipation at TC = 25°C. The device exhibits fT = 4MHz and switching times of ton = 0.7µs, ts = 4.5µs, tf = 0.8µs under standardized resistive-load test conditions (VCC = 125V, IB1 = –IB2 = 0.4A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 450V - Maximum collector-emitter voltage before avalanche under open-base condition; defines primary DC blocking capability in SMPS primary switches. |
| BVCES | 700V - Collector-emitter breakdown with base shorted to emitter; ensures margin against voltage spikes during switching transitions. |
| IC (cont) | 3.2A - Continuous collector current rating; sets maximum average output power capability in linear or pulse-width modulated operation. |
| VCE(sat) | 1.0V max at IC = 3A, IB = 0.75A - Saturation voltage directly impacts conduction loss and thermal load in hard-switched applications. |
| hFE | 20–35 at IC = 1–2A - DC current gain range determines required base drive strength and influences gate driver sizing in discrete BJT-based designs. |
| RθJC | 6.25°C/W - Junction-to-case thermal resistance; defines heatsink interface requirement for maintaining TJ ≤ 150°C at rated power. |
| ESD HBM | 8000V - Human Body Model ESD rating per JESD22-A114; indicates robustness during board assembly and handling. |
Pinout & Package
APT13005STF-G1 is housed in a TO-126 molded plastic package with matte tin-plated terminals, UL 94V-0 flammability rating, and approximate weight of 400mg. Pin identification is standardized across Diodes' TO-126 power transistors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current-carrying terminal connected to high-side switch node | Electrically tied to internal die substrate; requires minimum creepage distance per IEC 62368-1 for >400V applications. |
| Emitter (E) | Current return path and reference node for base drive | Serves as power ground reference; must be low-inductance connection to minimize switching noise coupling. |
| Base (B) | Control input for forward-biased junction | Requires current-limited drive (IB ≤ 1.6A continuous) to ensure reliable saturation without thermal runaway. |
Key Features
| Feature | Design Value |
|---|---|
| High voltage blocking | 700V BVCES enables use in 230VAC universal-input SMPS without external snubbers in many designs. |
| Lead-free & green compliance | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive and industrial environmental mandates. |
| Thermal robustness | Rated for operation from –65°C to +150°C junction temperature, supporting extended life in enclosed LED drivers. |
| Standardized pinout | TO-126 footprint matches legacy designs and simplifies drop-in replacement evaluation for obsolete parts. |

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 |
|---|---|---|---|
| APT13003STF-G1 | Lower VCEO (400V) and IC (2.0A); identical TO-126 package and pinout | Restricted to 115VAC-only or low-power 230VAC designs with reduced safety margin | Select only when system peak voltage remains below 350V and average load current ≤ 1.8A. |
| MJD13005G | Same VCEO (450V) and IC (3.0A), but TO-252 package and higher RθJC (7.5°C/W) | Requires larger PCB footprint and enhanced thermal relief for equivalent power dissipation | Prefer when surface-mount assembly is mandatory and thermal management allows for lower power derating. |
Compared with APT13005STF-G1, APT13003STF-G1 trades voltage headroom for cost reduction in low-line applications, while MJD13005G offers SMT compatibility at the expense of thermal efficiency and requires revised layout for thermal vias and copper area.

FAQ
Is APT13005STF-G1 still in active production?
No, APT13005STF-G1 is officially obsolete and discontinued per Diodes Incorporated's product change notice. Aetrix Electronics maintains limited legacy stock with full traceability and supports last-time buy programs for qualified customers with documented end-of-life transition plans.
What is the difference between APT13005STF-G1 and APT13005SU-G1?
APT13005SU-G1 uses the same die but is packaged in TO-126 with GU13005S marking and shipped in bulk (4000 units/box), whereas APT13005STF-G1 is TO-126 with APT13005STF-G1 marking and shipped in tubes (3600 units/box); both share identical electrical specs and thermal ratings.
Can APT13005STF-G1 replace MJE13005 in existing designs?
Yes - APT13005STF-G1 shares identical TO-126 pinout, VCEO (450V), IC (3.2A), and hFE range with MJE13005, and exceeds it in BVCES (700V vs. 600V) and ESD HBM (8kV vs. 2kV), making it a direct functional upgrade with improved surge tolerance.
Does APT13005STF-G1 meet AEC-Q101 requirements for automotive use?
No - while Diodes offers AEC-Q101-qualified variants in the same family (e.g., APT13005S-AQ), APT13005STF-G1 is not certified to AEC-Q101. It lacks PPAP documentation, IATF 16949-controlled manufacturing records, and automotive-grade stress test reports required for automotive applications.
