Product details
Overview
APT13003SZTR-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. It serves as a switching element in low-power AC-DC SMPS for battery chargers, LED lighting, and STB/DVD power supplies.
For engineers reviewing the APT13003SZTR-G1 datasheet, APT13003SZTR-G1 pinout, APT13003SZTR-G1 application, or APT13003SZTR-G1 equivalent, key selection criteria include VCEO ≥ 450V, IC ≥ 1.3A, TO92 thermal resistance (RθJA = 113.6°C/W), and automotive-grade qualification readiness.
Technical Context
This NPN bipolar junction transistor operates in linear or saturated switching mode with DC current gain (hFE) of 13–30 at IC = 0.5A/1.0A and VCE = 2V. Its safe operating area supports 1.3A DC and 2.6A peak pulse under defined duty cycle constraints.
Designed for high-voltage isolation in compact SMPS topologies, it features 8000V HBM ESD rating and 4MHz transition frequency (fT), enabling stable operation in flyback and buck-derived converters up to ~100kHz switching frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 450V - Maximum collector-emitter voltage before avalanche conduction in open-base condition; defines primary voltage blocking capability in flyback snubber or primary switch roles. |
| BVCES | 700V - Collector-emitter breakdown with base shorted to emitter; enables robust overvoltage margin during transient clamping or inductive turn-off spikes. |
| IC (cont.) | 1.3A - Continuous collector current rating at TA = 25°C; sets maximum sustained output power in <1W SMPS designs with adequate heatsinking. |
| RθJA | 113.6°C/W - Junction-to-ambient thermal resistance in free-air; determines required derating above 25°C ambient (e.g., 0.5W max at 70°C). |
| hFE | 13–30 - DC current gain range across 0.5–1.0A; informs base drive design (e.g., IB ≥ 33mA needed for IC = 1A at hFE = 30). |
| VCE(sat) | 0.3–0.6V - Saturation voltage at IC = 0.5–1.0A; directly impacts conduction loss (e.g., ≤0.6W dissipation at 1A). |
| fT | 4MHz - Transition frequency; supports reliable switching in sub-100kHz SMPS without excessive storage time penalties. |
Pinout & Package
APT13003SZTR-G1 uses the TO92 (Type C) molded plastic package with joggled legs, 200mg mass, UL 94V-0 flammability rating, and matte tin terminals. Pin identification follows flat-face view: left-to-right = Emitter (E), Collector (C), Base (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 sets reference for base drive biasing. |
| C (Collector) | High-voltage output terminal | Interfaces with primary winding or HV rail; must maintain ≥0.5mm creepage to adjacent pins per high-voltage safety guidelines. |
| B (Base) | Control input terminal | Receives current-limited drive signal; requires series resistor to limit IB ≤ 0.65A and ensure saturation under worst-case hFE. |
Key Features
| Feature | Design Value |
|---|---|
| High voltage blocking | BVCEO = 450V and BVCES = 700V enable use in 230VAC-input SMPS without external clamping networks. |
| Lead-free & green compliance | RoHS 3 compliant with <900ppm Br/Cl and <1000ppm Sb; meets automotive change-control requirements upon request. |
| Robust ESD protection | 8000V HBM rating reduces risk of handling damage during manual assembly or rework in production environments. |
| Thermal performance | RθJC = 83.3°C/W allows localized heatsinking via PCB copper pour under the collector tab (TO92 Type C variant). |
Applications
| Mobile Phone Charger | DVD/STB Power Supply |
|---|---|
|
Use Scenario: 5–12W isolated flyback converter in wall-wart adapters for smartphones and tablets. IC Role / Device Role / Timing Role: Primary-side switching transistor controlling energy transfer to secondary winding. Use Value: 450V VCEO withstands reflected output voltage plus leakage spike; 1.3A IC supports typical 1A output at 5–12V. |
Use Scenario: Standby and main power supply in set-top boxes and DVD players with dual-rail outputs. IC Role / Device Role / Timing Role: Main switch in quasi-resonant or fixed-frequency flyback topology. Use Value: 700V BVCES provides margin against 400V DC bus transients; TO92 footprint simplifies layout in space-constrained chassis. |
| LED Lighting Driver | Industrial Control PSU |
|
Use Scenario: Constant-current offline LED driver for downlights and panel lights (10–25W). IC Role / Device Role / Timing Role: Primary switch regulating LED string current via primary-sense feedback. Use Value: 4MHz fT ensures clean gate drive response; 0.3V VCE(sat) minimizes conduction loss at 350–700mA LED currents. |
Use Scenario: Auxiliary 5V/12V supply for PLC I/O modules and sensor interface boards. IC Role / Device Role / Timing Role: Low-cost, discrete switching element in low-power auxiliary SMPS. Use Value: 8000V HBM ESD rating improves field reliability in electrically noisy industrial environments. |
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 VCEO (450V), but TO220 package (RθJA = 65°C/W); higher PD (1.8W) and ICM (4A). | Requires heatsink for >0.8A continuous; unsuitable for TO92 footprint replacement. | Select when thermal budget exceeds TO92 limits and board space permits TO220 mounting. |
| 2SC4110 | Lower VCEO (400V), same TO92 package; hFE = 10–20, RθJA = 125°C/W. | Not suitable for 230VAC inputs without derating; reduced safe operating area at high VCE. | Acceptable only in 115VAC-only or low-derate designs where 400V margin suffices. |
Compared with MJD13003G and 2SC4110, APT13003SZTR-G1 uniquely balances TO92 form factor, 450V/1.3A rating, and 8000V HBM robustness-making it optimal for cost-sensitive, space-constrained 230VAC SMPS where thermal load stays below 1W.

FAQ
Is APT13003SZTR-G1 still in active production?
No-Diodes Incorporated has marked APT13003S as obsolete (DS36307 Rev. 4, June 2021). Aetrix Electronics maintains legacy inventory and offers controlled distribution with full traceability, but no new wafer starts are planned. Customers should initiate redesign evaluation using qualified alternatives.
What is the correct pinout orientation for APT13003SZTR-G1 in TO92 (Type C)?
With the flat face toward the viewer and leads pointing downward, the left-to-right pin order is Emitter (E), Collector (C), Base (B). This matches the "Flat Face View" diagram on page 2 of DS36307 and is confirmed by Diodes' official package outline PL-001C.
Can APT13003SZTR-G1 be used in automotive applications?
While not pre-qualified to AEC-Q101, Diodes states that automotive-grade versions with PPAP capability and IATF 16949 manufacturing can be made available upon direct request. Standard APT13003SZTR-G1 is intended for commercial/industrial use only.
How does the 700V BVCES rating impact circuit protection design?
BVCES = 700V (with base-emitter shorted) provides critical margin against voltage overshoot during turn-off in inductive circuits. It allows omission of external TVS clamps in many 230VAC flyback designs where reflected voltage + leakage spike remains below 650V, reducing BOM count and cost.
