SMC Diode Solutions 182NQ030-1 Schottky Rectifier Diode Equivalent & Substitute Parts

Part Overview

The SMC Diode Solutions 182NQ030-1 is an active Schottky rectifier diode rated for 30 V DC reverse voltage and 180 A average rectified current. This component is designed for chassis mount applications in the HALF-PAK (PRM1-1) package configuration. The diode operates across a junction temperature range of -55°C to 150°C and is classified as a fast recovery device with switching characteristics suitable for high-current rectification circuits.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative part numbers may be sourced due to inventory availability, packaging format differences, or supply chain requirements while preserving functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 182NQ030-1 and 182NQ030R-1 are active products manufactured by SMC Diode Solutions and maintain full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts is based on the following engineering considerations:

Electrical Equivalence: Both parts deliver identical electrical performance across all critical parameters including reverse voltage rating, average rectified current, forward voltage drop, and reverse leakage current. The capacitance variance (7700 pF versus 7000 pF) represents a 9% difference within acceptable tolerance for Schottky diode applications and does not affect functional substitution.

Mechanical Compatibility: Both parts utilize the HALF-PAK (PRM1-1) chassis mount package, ensuring identical mechanical fit and thermal interface characteristics in circuit board layouts and heat sink assemblies.

Compliance Status: Both parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, confirming suitability for standard manufacturing and storage environments without special handling requirements.

Packaging Availability: The primary distinction between these parts is packaging format. The 182NQ030-1 is supplied in Bulk packaging, while the 182NQ030R-1 is supplied in Box packaging. Selection depends on procurement quantity requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can the 182NQ030R-1 be used as a direct replacement for the 182NQ030-1 in existing circuit designs?

A: Yes. The 182NQ030R-1 is electrically and mechanically equivalent to the 182NQ030-1. Both parts share identical voltage ratings (30 V), current ratings (180 A), forward voltage characteristics (510 mV @ 180 A), and thermal operating range (-55°C to 150°C). The HALF-PAK (PRM1-1) chassis mount package is identical, ensuring compatibility with existing PCB layouts and thermal management systems.

Q: What is the significance of the capacitance difference between these parts?

A: The 182NQ030-1 specifies 7700 pF capacitance at 5V and 1 MHz, while the 182NQ030R-1 specifies 7000 pF under identical measurement conditions. This 700 pF variance represents approximately 9% difference and falls within normal manufacturing tolerance for Schottky diode junction capacitance. This parameter does not affect rectification performance or switching characteristics in standard power conversion applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the 182NQ030-1 and 182NQ030R-1 carry identical compliance certifications: ROHS3 Compliant, REACH Affected, MSL Level 1 (Unlimited), ECCN EAR99, and HTSUS 8541.10.0080. Both parts are suitable for applications requiring regulatory compliance in industrial and commercial markets.

Q: What is the difference between Bulk and Box packaging?

A: Bulk packaging (182NQ030-1) and Box packaging (182NQ030R-1) represent different supply formats for the same component. Bulk packaging is typically used for high-volume procurement and automated assembly operations, while Box packaging is used for smaller quantity orders and manual assembly processes. The electrical and mechanical specifications of the diode itself remain unchanged regardless of packaging format.

Q: Can these parts be used interchangeably in high-current rectification circuits?

A: Yes. Both parts are rated for 180 A average rectified current and maintain identical forward voltage characteristics (510 mV @ 180 A). The HALF-PAK chassis mount configuration provides equivalent thermal interface and mechanical mounting for both parts, ensuring consistent performance in high-current power conversion applications.

Q: What is the base product number for these parts?

A: The base product number for both the 182NQ030-1 and 182NQ030R-1 is 182NQ. This designation identifies the core Schottky diode design, with the suffix (-1 or R-1) indicating specific packaging and supply format variations.
