Diodes - Rectifiers - Arrays

1. Overview

Rectifier arrays are discrete semiconductor devices integrating multiple diodes in a single package to perform AC-to-DC conversion, voltage clamping, or signal demodulation. These arrays are critical in power management systems, enabling efficient energy conversion and circuit protection. Their compact design reduces PCB space requirements while maintaining reliability in high-current or high-voltage applications.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Double Diode Arrays	Two independent diodes in a shared package, common cathode/anode configuration	Full-bridge rectifiers in SMPS
Quad Diode Arrays	Four diodes arranged as dual series/parallel circuits	Three-phase rectification in industrial equipment
High-Voltage Arrays	Rated above 600V with enhanced dielectric isolation	Power factor correction circuits
Low-Voltage Schottky Arrays	30V with low forward voltage drop (0.15-0.45V)	DC-DC converters in mobile devices

3. Structure and Composition

Rectifier arrays typically use silicon epitaxial planar technology with diffusion-bonded junctions. Standard packages include:

TO-220/TO-247 for high-power applications
SOIC/SOT-23 for surface-mount designs
Dual-inline packages (DIP) with through-hole mounting

Internal structure features monolithically integrated diodes with shared thermal vias, while advanced devices employ silicon carbide (SiC) for higher efficiency.

4. Key Technical Parameters

Parameter	Description	Importance
Max Repetitive Reverse Voltage (V_RRM)	600V-1600V ratings determine circuit insulation level	Ensures safe operation under voltage spikes
Forward Current (I_F(AV))	1A-50A average current handling capacity	Dictates power delivery capability
Forward Voltage Drop (V_F)	0.55V-1.1V (Si), 0.15V-0.45V (Schottky)	Impacts conduction losses and efficiency
Operating Junction Temperature (T_J)	-55 C to 175 C	Determines thermal stability
Reverse Recovery Time (t_rr)	10ns-2 s	Affects switching performance

5. Application Areas

Power Supplies: Switch-mode power supplies (SMPS), battery chargers
Automotive: Alternator rectification, onboard chargers
Industrial: Motor drives, welding inverters
Renewables: Solar micro-inverters, wind turbine converters
Consumer: TV power adapters, LED lighting drivers

6. Leading Manufacturers and Products
