Product details
Overview
APD245VG-G1 from BCD Semiconductor Manufacturing Limited is a 45 V, 2.0 A Schottky barrier rectifier in DO-15 package with low 0.5 V forward voltage at 2.0 A, 50 A surge capability, and −65 °C to +125 °C operating junction temperature-used for polarity protection and free-wheeling in DC-DC converters.
For engineers reviewing the APD245VG-G1 datasheet, APD245VG-G1 pinout, APD245VG-G1 application, or APD245VG-G1 equivalent, key selection criteria include forward voltage drop at rated current, peak surge rating, thermal resistance (52 °C/W), reverse leakage at 100 °C, and green RoHS-compliant packaging.
Technical Context
This Schottky diode uses a metal-semiconductor junction to achieve fast switching and minimal conduction loss. Its 0.5 V VF at 2.0 A enables high-efficiency rectification in low-voltage power stages, while the 50 A IFSM rating supports transient overload handling in inverter and converter topologies.
The device operates across −65 °C to +125 °C with 0.5 mA IR at 25 °C and 10 mA at 100 °C, confirming stable blocking performance under thermal stress. Its DO-15 package provides standardized axial lead mounting and 52 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 36 V nominal systems. |
| IF(AV) | 2.0 A - Average forward current rating; defines continuous DC output capability in rectifier paths. |
| VF @ 2.0 A | 0.5 V - Forward voltage drop; directly determines conduction loss (1.0 W at 2.0 A) and thermal load. |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance. |
| θJA | 52 °C/W - Junction-to-ambient thermal resistance (DO-15); used to calculate junction temperature rise under load. |
| IR @ 45 V | 0.5 mA @ 25 °C / 10 mA @ 100 °C - Reverse leakage; impacts standby power and high-temp reliability. |
| TJ Range | −65 °C to +125 °C - Operating junction temperature range; validates use in automotive under-hood and industrial environments. |
Pinout & Package
APD245VG-G1 is housed in a DO-15 axial-leaded plastic package with cathode indicated by a band marking. The device has two terminals: anode and cathode, with no internal complexity or control logic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connects to lower-potential side of circuit; current flows into anode during forward bias. |
| Cathode | Output terminal for forward conduction | Marked with band; connects to higher-potential side; defines polarity protection orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.5 V at 2.0 A reduces conduction loss by >30% vs. standard PN rectifiers at same current. |
| High surge capability | 50 A non-repetitive peak surge withstand enables robustness against inductive kickback and startup transients. |
| Green RoHS-compliant packaging | "G1" suffix denotes halogen-free, lead-free, and environmentally compliant DO-15 housing per EU directives. |
| Wide temperature operation | −65 °C to +125 °C junction range supports deployment in unregulated ambient environments without derating. |
Applications
| DC-DC Converter Output Rectification | Polarity Protection |
|---|---|
Use Scenario: Secondary-side synchronous or Schottky rectification in isolated 5–24 V buck-derived DC-DC modules. IC Role / Device Role / Timing Role: Unidirectional current path with minimal forward loss and zero recovery time. Use Value: Enables >92% efficiency at 2 A output by limiting VF-related dissipation to 1.0 W. | Use Scenario: Input protection on 12 V/24 V industrial power supplies subject to accidental reverse battery connection. IC Role / Device Role / Timing Role: Blocking element placed in series with positive rail; conducts only during correct polarity. Use Value: Prevents damage to downstream regulators and controllers without adding active circuitry or delay. |
| Free-Wheeling Diode | Low-Voltage Inverter Snubber |
Use Scenario: Flyback path for inductive loads (e.g., solenoids, relays) driven by N-channel MOSFETs in 12–36 V systems. IC Role / Device Role / Timing Role: Provides low-loss recirculation path during switch-off, clamping inductive voltage spikes. Use Value: Limits VDS overshoot to <55 V using 45 V VRRM margin, reducing MOSFET stress and EMI. | Use Scenario: Snubbing commutation edges in 48 V-class motor drive inverters operating at 20–100 kHz. IC Role / Device Role / Timing Role: Fast-recovery passive clamp absorbing turn-off energy from bridge-leg inductance. Use Value: Suppresses ringing without RC network losses, leveraging near-zero reverse recovery charge (QRR ≈ 0). |

FAQ
What is the cathode identification method for APD245VG-G1?
The cathode is marked by a distinct color band on the DO-15 body, aligned with the cathode terminal as shown in Figure 2 of the datasheet. This band must be oriented toward the positive side of the load in polarity protection configurations.
Can APD245VG-G1 replace a standard PN rectifier like 1N5819?
Yes-APD245VG-G1 matches 1N5819's 40 V VRRM and 1 A IF(AV) rating but exceeds it with 2.0 A average current, 45 V rating, and lower 0.5 V VF. It is a direct upgrade where higher current and tighter thermal margins are needed.
Is APD245VG-G1 suitable for surface-mount assembly?
No-APD245VG-G1 uses the through-hole DO-15 axial package and is not compatible with SMT reflow or pick-and-place. For SMT equivalents, consider DO-214AC variants like APD245VRTR-G1.
What is the maximum allowable PCB trace width for 2.0 A continuous operation?
At 2.0 A and 70 °C ambient, a 1.5 mm (60 mil) wide external copper trace (1 oz/ft²) with 10 mm length achieves <10 °C rise. Internal layers require ≥2.0 mm width; thermal vias near pads improve θJA performance beyond the rated 52 °C/W.
