Product details
Overview
APT13003SU-G1 from Diodes Incorporated is a 450V NPN high-voltage power transistor in TO92 (Type C) package, rated for 1.3A continuous collector current, 700V collector-emitter breakdown (BVCES), and 9V emitter-base breakdown (BVEBO); used in low-power AC-DC SMPS for LED lighting and mobile device battery chargers.
For engineers reviewing the APT13003SU-G1 datasheet, APT13003SU-G1 pinout, APT13003SU-G1 application, or APT13003SU-G1 equivalent, key selection criteria include safe operating area at 125V clamp voltage, DC current gain (hFE = 13–30 at IC = 0.5–1.0A), VCE(sat) ≤ 0.6V, thermal resistance RθJA = 113.6°C/W, and RoHS-compliant green molding compound.
Technical Context
This NPN bipolar junction transistor operates in linear and switching modes with guaranteed BVCES ≥ 700V and BVCEO ≥ 450V, enabling use in flyback and buck-derived topologies where high-voltage blocking and moderate current handling are required. Its TO92 package supports through-hole mounting with 200mg mass and UL 94V-0 flammability rating.
Electrical behavior is characterized by hFE = 13–30 (IC = 0.5–1.0A, VCE = 2V), VCE(sat) ≤ 0.6V (IC = 1A, IB = 0.25A), and fT = 4MHz (IC = 0.1A, VCE = 10V), supporting operation up to several hundred kHz in SMPS designs while maintaining thermal stability across –65°C to +150°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 450V - Maximum collector-emitter voltage before avalanche under open-base condition; defines primary voltage rating for SMPS switch node placement. |
| BVCES | 700V - Collector-emitter breakdown with base shorted to emitter; enables robustness against voltage transients in discontinuous conduction mode. |
| IC (cont.) | 1.3A - Continuous collector current limit; sets maximum average output power capability in 20–50W AC-DC converters. |
| VCE(sat) | ≤0.6V @ IC=1A, IB=0.25A - Low saturation voltage reduces conduction loss and improves efficiency in low-duty-cycle switching applications. |
| RθJA | 113.6°C/W - Junction-to-ambient thermal resistance in free-air; determines required PCB copper area and heatsinking for 1.1W PD derating. |
| hFE | 13–30 @ IC=0.5–1.0A - DC current gain range impacts base drive design margin and switching speed trade-offs in discrete BJT-based controllers. |
Pinout & Package
APT13003SU-G1 uses TO92 (Type C) package with molded plastic case, matte tin-plated terminals, and flat-face orientation. Pin identification follows standard TO92 layout: Emitter (E), Collector (C), Base (B) - viewed from flat side with leads down, left-to-right order is E-C-B.
| 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 loop. |
| C (Collector) | High-voltage switch node | Connected to transformer primary or rectified input rail; must maintain ≥0.5mm creepage to adjacent traces per high-voltage safety standards. |
| B (Base) | Control input | Driven by resistor-coupled controller IC or optocoupler feedback; requires ≥0.25A peak drive for full saturation at 1A collector current. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | BVCES ≥ 700V ensures reliable operation under 400VDC bus surges common in universal-input offline SMPS. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets IEC 61249-2-21 and automotive environmental requirements. |
| RoHS-compliant finish | Matte tin plating on leads satisfies MIL-STD-202 solderability and EU Directive 2015/863/EU (RoHS 3) compliance. |
| Thermal performance | RθJC = 83.3°C/W enables direct PCB copper pad conduction cooling without external heatsink in <1.5W dissipation applications. |
Applications
| LED Lighting Power Supply | Smartphone Battery Charger |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-voltage power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD13003G | Same TO92 package, identical BVCEO (450V) and IC (1.3A), but BVCES = 600V (vs. 700V) and hFE min = 10 (vs. 13). | Limited surge immunity in 230VAC+ environments; requires tighter input clamping in high-line applications. | Select when cost is prioritized over transient robustness and design margin is verified via SOA analysis. |
| 2SC4110 | TO92, BVCEO = 400V, IC = 1.0A, hFE = 10–20, RθJA = 125°C/W - lower voltage/current ratings and higher thermal resistance. | Suitable only for 115VAC-only or low-power (<8W) designs; not recommended for universal-input or LED driver use. | Choose only for legacy replacement in existing 115VAC-only products with validated thermal margin and no line-voltage upgrade plans. |
Compared with MJD13003G and 2SC4110, APT13003SU-G1 provides superior 700V BVCES headroom for transient suppression, higher minimum hFE for consistent base drive, and lower RθJA for improved thermal headroom-making it preferred for new universal-input SMPS designs above 10W.

FAQ
Is APT13003SU-G1 still in active production?
No - APT13003SU-G1 is marked obsolete in Diodes' official documentation (DS36307 Rev. 4-4, June 2021). However, Aetrix Electronics maintains legacy inventory with full traceability and offers extended supply support including last-time buy coordination and cross-reference assistance for qualified replacements.
What is the correct pinout orientation for APT13003SU-G1 in TO92 package?
When viewing the flat face of the TO92 package with leads pointing downward, the left-to-right pin order is Emitter (E), Collector (C), Base (B). This matches Diodes' official schematic diagram and mechanical outline drawing for Type C TO92 devices.
Can APT13003SU-G1 replace MJD13003 in existing designs?
Yes - APT13003SU-G1 shares identical TO92 footprint, pinout, and electrical ratings (VCEO, IC, hFE range), with enhanced BVCES (700V vs. 600V) and lower RθJA (113.6°C/W vs. ~120°C/W). No PCB or schematic changes are needed; improved surge margin may allow reduction of snubber components.
Does APT13003SU-G1 meet AEC-Q101 for automotive use?
No - the datasheet explicitly states that APT13003SU-G1 is not AEC-Q101 qualified. For automotive applications, Diodes recommends contacting their sales team for PPAP-capable, IATF 16949-manufactured alternatives such as the APT13003Q series, which undergo stress testing per AEC-Q101 Rev D.
