Overview
The Powerex A170PB is a general-purpose rectifier diode rated for 1200 V DC reverse voltage and 100 A forward current. It utilizes a DO-205AA (DO-8) package with chassis stud mounting. The component is RoHS compliant and lead-free, designed for high-power industrial applications requiring robust thermal management and reliable single-direction current conduction.
Feature Summary
- High-voltage blocking capability for demanding power circuits
- Robust mechanical construction via stud mount design
- Compliance with environmental standards including RoHS
Applications
- Industrial motor drives
- Power supply rectification
- Inverter bridge circuits
Procurement Notes
Verify the exact datasheet revision and manufacturer lot codes upon order confirmation. Confirm that the DO-205AA package dimensions match your chassis requirements. Ensure proper torque specifications are applied during installation to maintain electrical integrity and thermal performance. Check for any specific handling instructions regarding electrostatic discharge protection.
Selection Notes
Select this component when a 1200 V rating and 100 A continuous current capacity are required in a stud-mount configuration. Consider the thermal resistance characteristics of the DO-205AA package for heat sink selection. Ensure the application environment supports the operating temperature range specified in the official documentation. Verify compatibility with existing circuit protection mechanisms.
Part Context
This device belongs to the Powerex discrete semiconductor portfolio, specifically within the single diode category. It serves as a standard rectification solution for medium-to-high power electronics. The DO-205AA package is a legacy form factor often used in heavy-duty industrial equipment where direct chassis mounting provides superior thermal dissipation compared to surface-mount alternatives.
Replacement Considerations
Consult official cross-reference lists from Powerex or authorized distributors for verified substitutes. Ensure replacement parts match the 1200 V / 100 A ratings and DO-205AA footprint. Do not assume functional equivalence based solely on package similarity without verifying electrical parameters.
