Product details
Overview
2A01G-T from Diodes Incorporated is a 2.0A glass passivated general-purpose rectifier diode in DO-15 package, rated for 50V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 2.0A, and 65A non-repetitive surge current. It serves as a primary AC-to-DC conversion element in low-voltage power supplies, battery chargers, and DC adapter input stages.
For engineers reviewing the 2A01G-T datasheet, 2A01G-T pinout, 2A01G-T application, or 2A01G-T equivalent, key selection criteria include VRRM margin vs. input AC peak, thermal derating above 55°C ambient, IFSM capability for inrush handling, and DO-15 PCB footprint compatibility with legacy through-hole designs.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60Hz line frequency. Its glass passivated junction ensures stable reverse leakage (5.0µA @ 25°C) and robust surge tolerance without metallization degradation.
Thermal performance is defined by RθJA = 60°C/W with leads held at ambient at 9.5mm from case; derating begins at 55°C ambient per Fig. 1, reaching 0A at 175°C. Capacitance is low (40pF @ 1MHz, 4V reverse), minimizing high-frequency switching noise in linear supply inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50V - Maximum peak reverse voltage before breakdown; sets minimum AC input crest voltage rating. |
| IO @ TA=55°C | 2.0A - Continuous average forward current under specified thermal condition; defines steady-state power delivery capacity. |
| VFM @ IF=2.0A | 1.1V - Forward drop at rated current; determines conduction loss (2.2W max at full load). |
| IFSM | 65A - Single half-sine surge rating; supports capacitor-input filter inrush without failure. |
| IRM @ 25°C | 5.0µA - Reverse leakage at rated DC blocking voltage; impacts standby power in high-impedance circuits. |
| RθJA | 60°C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under given power dissipation. |
| CT @ 1MHz | 40pF - Junction capacitance at 4V reverse bias; affects EMI filtering and high-frequency rectification fidelity. |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), axial leaded, cathode band marked, 0.4g weight. Polarity: Cathode band denotes cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input connection point | Accepts alternating input; must withstand full negative half-cycle reverse voltage. |
| Cathode | DC output connection point | Delivers rectified positive half-cycle; connects to bulk capacitor or regulator input. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Prevents moisture-induced junction corrosion and enables stable long-term IR performance in humid environments. |
| 65A non-repetitive surge rating | Withstands cold-start inrush into large electrolytic capacitors without parametric shift or failure. |
| Lead-free, RoHS-compliant finish | Enables compliance with environmental regulations and compatibility with modern reflow/soldering processes. |
| DO-15 mechanical standardization | Ensures direct replacement in existing through-hole PCB layouts designed for industry-standard 2A rectifiers. |
Applications
| AC/DC Wall Adapters | Battery Charger Input Stage |
|---|---|
Use Scenario: Converts 120/230VAC mains to unregulated DC for downstream linear regulation or switching control circuitry. IC Role / Device Role / Timing Role: Primary rectifier in bridge or half-wave configuration; defines input power path integrity. Use Value: Low VFM minimizes heat generation in compact enclosures; 50V VRRM provides sufficient margin over 35V RMS input peaks. | Use Scenario: Rectifies transformer secondary output in NiMH or Li-ion charger front-end before current sensing and charge control. IC Role / Device Role / Timing Role: Unidirectional current gate enabling safe charging polarity; handles intermittent high-current pulses during equalization. Use Value: 65A IFSM accommodates transformer saturation surges; DO-15 form factor fits space-constrained charger PCBs. |
| Industrial Control Power Supplies | LED Driver Auxiliary Supply |
Use Scenario: Provides isolated auxiliary DC for PLC I/O modules, relay drivers, and sensor interface circuitry. IC Role / Device Role / Timing Role: Input-stage rectifier feeding linear regulators powering logic and analog sections. Use Value: Stable IRM <5µA prevents false triggering in high-impedance control lines; -65°C to +175°C rating supports wide ambient operation. | Use Scenario: Generates low-power bias voltage for LED driver ICs in constant-current streetlight or signage systems. IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback or buck-derived auxiliary winding supply. Use Value: 40pF CT reduces high-frequency coupling into sensitive current-sense nodes; DO-15 allows manual rework in field-serviceable units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4001-T | Same DO-15 package, but lower 35V VRRM and higher 1.2V VFM at 1A. | Not suitable for 50V-rated input circuits; limited surge margin (30A IFSM). | Select only when input AC peak remains below 25V and surge demands are minimal. |
| ES1D-E3/57T | Surface-mount SMA package, 200V VRRM, 1.7A IO, faster recovery (~35ns), higher cost. | Requires PCB redesign; better for high-frequency or higher-voltage designs where size matters. | Choose for SMT production or >100V applications; not a drop-in replacement for DO-15 through-hole layouts. |
Compared with 1N4001-T, 2A01G-T offers higher voltage margin and surge robustness; versus ES1D-E3/57T, it provides legacy-compatible through-hole assembly and lower conduction loss at 2A, but lacks fast-recovery capability.

FAQ
Is 2A01G-T suitable for capacitive-load applications?
No - the datasheet explicitly requires 20% current derating for capacitive loads due to increased peak current stress on the junction. For capacitor-input filters, use only up to 1.6A average output current to maintain reliability and avoid premature failure.
What is the maximum operating temperature for continuous 2.0A operation?
Continuous 2.0A operation is rated only up to 55°C ambient temperature. Above that, current must be linearly derated per Fig. 1; at 100°C ambient, maximum allowable IO drops to approximately 1.2A to prevent junction overheating beyond 175°C.
Does 2A01G-T have a specified reverse recovery time?
No - the datasheet does not specify trr or recovery characteristics. This part is optimized for 50/60Hz line-frequency rectification, not high-frequency switching; its behavior under fast transitions is not characterized or guaranteed.
Can 2A01G-T replace 1N4001 in existing designs?
Yes, with verification - both are DO-15 axial devices with identical pinout and polarity marking. However, 2A01G-T's higher 50V VRRM and 65A IFSM improve margin, while its 2.0A rating exceeds 1N4001's 1.0A, allowing potential current headroom increase if thermal design permits.
