Product details
Overview
1N5822 A0G from Taiwan Semiconductor is a 40 V, 3 A Schottky barrier rectifier in DO-201AD package, featuring 0.525 V forward voltage at 3 A and 70 A surge capability, used in DC-DC converters and switching power supplies where low conduction loss and fast recovery are critical.
For engineers reviewing the 1N5822 A0G datasheet, 1N5822 A0G pinout, 1N5822 A0G application, or 1N5822 A0G equivalent, key selection criteria include repetitive peak reverse voltage (40 V), forward voltage drop (0.525 V @ 3 A), thermal resistance (40 °C/W), junction temperature range (–55 to +125 °C), and DO-201AD mechanical compatibility.
Technical Context
This Schottky rectifier uses a single-die silicon structure with guard ring protection to withstand transient overvoltage events. Its low VF and absence of minority-carrier storage enable efficient high-frequency operation without reverse recovery tail current.
The device operates within a junction temperature range of –55 °C to +125 °C and exhibits 500 µA maximum reverse leakage at 25 °C and rated VR, rising to 10 mA at 100 °C - a behavior consistent with thermally activated Schottky barrier conduction.
Key Specifications

| VRRM | 40 V - maximum repetitive reverse blocking voltage; defines safe operating limit in rectification circuits |
| IF | 3 A - continuous forward current rating; determines steady-state power handling capacity |
| VF @ 3 A | 0.525 V - forward voltage drop at rated current; directly impacts conduction loss and thermal design |
| IFSM | 70 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance |
| RθJA | 40 °C/W - junction-to-ambient thermal resistance; enables PCB-level thermal estimation without heatsink |
| TJ Range | –55 to +125 °C - operational junction temperature window; suitable for industrial ambient environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS340A | 40 V VRRM, 3 A IF, VF = 0.52 V @ 3 A, DO-201AD package, same pinout | No AEC-Q101 qualification; lower IR spec (200 µA max @ 25 °C) | Preferred where automotive qualification is not required and tighter IR budget exists |
| SS34-HF | 40 V VRRM, 3 A IF, VF = 0.55 V @ 3 A, DO-201AD, RoHS/halogen-free | Higher VF increases conduction loss by ~50 mW at 3 A; no guard ring specified | Acceptable for cost-sensitive industrial designs where 0.025 V VF penalty is tolerable |
Compared with STPS340A and SS34-HF, the 1N5822 A0G provides verified guard ring protection and AEC-Q101 qualification - critical for automotive auxiliary supplies - while matching core electrical specs and mechanical fit in DO-201AD layouts.

FAQ
What is the maximum repetitive peak reverse voltage rating for the 1N5822 A0G?
The 1N5822 A0G has a maximum repetitive peak reverse voltage (VRRM) rating of 40 V. This value is fixed for the 1N5822 variant and distinguishes it from the 1N5820 (20 V) and 1N5821 (30 V). Exceeding 40 V in repetitive reverse bias may cause breakdown. The 1N5822 A0G must be applied within this limit in all operating conditions, including transients and ringing.
Does the 1N5822 A0G have AEC-Q101 qualification?
No - the 1N5822 A0G is not AEC-Q101 qualified. Per Taiwan Semiconductor's ordering information, only part numbers ending in "H" (e.g., 1N5822H) or "HA0G" carry AEC-Q101 qualification. The "A0G" suffix denotes green, ammo-packaged DO-201AD units without automotive qualification. For automotive applications, specify 1N5822H or 1N5822HA0G instead of 1N5822 A0G.
What is the forward voltage drop of the 1N5822 A0G at its rated current?
The 1N5822 A0G exhibits a typical forward voltage drop (VF) of 0.525 V at 3 A and 25 °C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating. At elevated temperatures or higher currents, VF decreases slightly due to negative temperature coefficient of Schottky diodes.
What package type does the 1N5822 A0G use, and what are its key mechanical features?
The 1N5822 A0G uses the DO-201AD axial-leaded package. Key mechanical features include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002 solderability, JESD 201 Class 2 whisker resistance, cathode polarity marked by a band, and a typical weight of 1.10 g. Its dimensions conform to standard DO-201AD outlines.
How does the thermal performance of the 1N5822 A0G affect PCB layout decisions?
The 1N5822 A0G has a junction-to-ambient thermal resistance (RθJA) of 40 °C/W in free-air conditions. To maintain TJ ≤ 125 °C at 3 A (dissipating ~1.58 W), ambient temperature must stay below ~65 °C unless additional copper area or airflow is provided. PCB layout should allocate ≥ 1 cm² of 2-oz copper connected to both leads to reduce effective RθJA by ~15–20 °C/W.
