Product details
Overview
PD3SD2580-7 from Diodes Incorporated is a surface-mount fast switching diode in PowerDI®323 package, rated for 80 V peak repetitive reverse voltage, 250 mA forward continuous current, and 4.0 ns reverse recovery time. It serves as a high-speed signal or clamp diode in low-power analog and digital interface circuits, including USB data line protection and logic-level translation.
For engineers reviewing the PD3SD2580-7 datasheet, PD3SD2580-7 pinout, PD3SD2580-7 application, or PD3SD2580-7 equivalent, key selection criteria include its 2.3 pF junction capacitance at 0 V, 0.855 V forward voltage at 10 mA, AEC-Q101 qualification, RoHS-compliant green molding compound, and thermal resistance of 250 °C/W on FR-4 PCB.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for fast minority-carrier recombination, enabling sub-5 ns reverse recovery with minimal stored charge. Its low 2.3 pF capacitance and 0.715–1.25 V forward voltage range across 1–150 mA support high-frequency signal integrity in 5 V and 3.3 V systems.
The device operates from −65 °C to +150 °C and is qualified per AEC-Q101 for automotive-grade reliability. Its PowerDI323 package delivers 500 mW power dissipation with industry-standard thermal performance on standard FR-4 layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4448WSF-7 | Same PowerDI323 package; 75 V VRRM, 4 ns trr, 0.875 V VF @ 10 mA | Slightly lower reverse voltage margin; identical thermal and capacitive behavior | Select when 75 V rating suffices and legacy sourcing is prioritized |
| BAT54CW-7-F | SOT-323 package; dual common-cathode configuration; 30 V VRRM, 5 ns trr, 0.33 V VF @ 10 mA | Lower voltage rating; Schottky architecture eliminates minority-carrier delay but increases leakage | Choose for ultra-low VF in 3.3 V systems where leakage <1 µA is acceptable |
Compared with 1N4448WSF-7 and BAT54CW-7-F, PD3SD2580-7 offers superior 80 V reverse standoff and AEC-Q101 qualification while maintaining identical 4 ns speed and 2.3 pF capacitance-making it optimal for automotive and industrial 5 V signal conditioning where reliability and voltage margin are critical.

FAQ
Is PD3SD2580-7 suitable for new designs despite the "NOT RECOMMENDED FOR NEW DESIGN USE" note?
Yes - the "NOT RECOMMENDED FOR NEW DESIGN USE" label applies only to the obsolete 1N4448WSF-7 reference shown in the datasheet's header, not to PD3SD2580-7 itself. PD3SD2580-7 is an active, AEC-Q101-qualified part with full production support and documented longevity through Diodes Incorporated's Product Longevity Program.
What is the maximum operating temperature for continuous use?
The PD3SD2580-7 has a specified operating junction temperature range of −65 °C to +150 °C. For continuous operation at full 250 mA forward current, ambient temperature must be limited to ≤70 °C on a standard FR-4 board with recommended pad layout, per the derating curve in Figure 6 of DS30720 Rev. 10-3.
Does PD3SD2580-7 have a built-in ESD protection structure?
No - PD3SD2580-7 is a passive fast-switching diode without integrated ESD protection circuitry. Its role in ESD protection schemes is as an external clamping element. System-level ESD robustness depends on proper PCB layout, series impedance, and coordination with TVS devices per IEC 61000-4-2 requirements.
Can PD3SD2580-7 replace 1N4148 in existing designs?
Yes - PD3SD2580-7 matches or exceeds 1N4148 specifications in all key parameters: 80 V vs. 100 V VRRM, 4 ns vs. 4 ns trr, 2.3 pF vs. 4 pF CT, and 0.855 V vs. 0.875 V VF @ 10 mA. Its PowerDI323 package is smaller than DO-35 but compatible with automated placement; thermal and electrical performance is equal or improved.
