PR1006GL-T Equivalent & Substitute Parts

Part Overview

The PR1006GL-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 800 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing production and maintenance applications. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional compatibility within defined parameter tolerances for 800 V, 1 A rectifier diode applications.

Substitution of the PR1006GL-T is determined by the following critical parameters:

Electrical Specifications:

Voltage - DC Reverse (Vr) (Max): 800 V minimum
Current - Average Rectified (Io): 1 A minimum
Voltage - Forward (Vf) (Max) @ If: 1.3 V or lower at 1 A
Current - Reverse Leakage @ Vr: 5 µA or lower at 800 V

Mechanical Specifications:

Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, or Axial configurations

Compliance & Status:

RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: direct manufacturer equivalents (identical specifications from Diodes Incorporated) and cross-manufacturer alternatives (functionally compatible from Vishay, onsemi, Micro Commercial Co, and Taiwan Semiconductor Corporation). Parts with fast recovery characteristics (≤500 ns) are distinguished from standard recovery parts (>500 ns) to support application-specific selection.

Engineering Selection Recommendations

Direct Equivalent (Preferred for Replacement):

PR1006G-T (Diodes Incorporated) is the direct active equivalent to PR1006GL-T. This part maintains identical electrical specifications (800 V, 1 A, 1.3 V forward voltage, 500 ns recovery time) and mechanical packaging (DO-41). The primary distinction is product status: PR1006G-T is active with 3100 units in stock, whereas PR1006GL-T is obsolete. This substitution requires no circuit redesign or validation.

Fast Recovery Alternatives (800 V, 1 A, ≤500 ns Recovery):

RGP10K-E3/54 and RGP10KE-E3/54 (Vishay General Semiconductor, SUPERECTIFIER® series) provide fast recovery performance identical to the PR1006GL-T (500 ns) with extended operating temperature range (-65°C to 175°C versus -65°C to 150°C). Both parts are active with adequate inventory. Package designation is DO-204AL (DO-41 equivalent). Forward voltage specification is 1.3 V at 1 A, matching the original part.

1N4947GP-TP (Micro Commercial Co) offers superior fast recovery performance (250 ns) with identical 800 V, 1 A ratings and 1.3 V forward voltage. This part is active in DO-41 package but operates within a narrower temperature range (-55°C to 150°C).

Standard Recovery Alternatives (800 V, 1 A, >500 ns Recovery):

1N4006-E3/73, 1N4006-TP, 1N4006G, 1N4006GP-E3/54, and 1N4006GP-E3/73 are standard recovery rectifier diodes rated 800 V, 1 A. These parts feature lower forward voltage (1.0 to 1.1 V at 1 A) compared to the PR1006GL-T (1.3 V), resulting in reduced power dissipation. All are active with substantial inventory. Operating temperature ranges vary: Vishay parts extend to 175°C; Micro Commercial Co and Taiwan Semiconductor Corporation parts operate to 150°C. Package options include DO-41 and DO-204AL configurations.

1N4006RLG (onsemi) is classified as Not For New Designs but remains available with 62,255 units in stock. This axial package part exhibits higher reverse leakage (10 µA at 800 V versus 5 µA) and is suitable for legacy system maintenance only.

Compliance Verification:

All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the regulatory status of PR1006GL-T. All parts carry EAR99 export classification and HTSUS code 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can PR1006G-T directly replace PR1006GL-T without circuit modification?

A: Yes. PR1006G-T is the direct active equivalent with identical electrical and mechanical specifications. The only difference is product status (active versus obsolete) and packaging format (cut tape versus original packaging). No circuit redesign is required.

Q: What is the difference between fast recovery (500 ns) and standard recovery (>500 ns) diodes?

A: Recovery time (trr) defines the interval required for reverse current to cease after the diode transitions from forward to reverse bias. Fast recovery diodes (≤500 ns) minimize switching losses and are preferred in high-frequency switching applications. Standard recovery diodes (>500 ns) are suitable for line-frequency rectification and general-purpose applications. The PR1006GL-T specifies 500 ns fast recovery performance. Substitutes with longer recovery times (1N4006 series at 2000 ns) are acceptable for low-frequency applications but introduce higher switching losses in high-frequency circuits.

Q: Are DO-41 and DO-204AL packages mechanically interchangeable?

A: DO-41 and DO-204AL are equivalent axial through-hole package designations for the same physical form factor. Parts specified as DO-204AL (DO-41) or DO-41 are mechanically and electrically interchangeable in PCB layouts designed for axial lead components. Verify PCB footprint compatibility before substitution.

Q: What is the significance of forward voltage (Vf) differences among substitute parts?

A: Forward voltage determines power dissipation during conduction. The PR1006GL-T specifies 1.3 V at 1 A. Substitute parts with lower Vf (1.0 to 1.1 V) dissipate less power and generate less heat. In high-current or continuous-duty applications, lower Vf substitutes reduce thermal stress. In low-current or intermittent applications, Vf differences are negligible. Verify thermal design margins before selecting lower-Vf alternatives in thermally constrained designs.

Q: Why do some substitute parts have higher operating temperature ranges?

A: Vishay SUPERECTIFIER® parts (RGP10K-E3/54, RGP10KE-E3/54, 1N4006GP-E3/54, 1N4006GP-E3/73) and onsemi 1N4006RLG specify -65°C to 175°C, compared to PR1006GL-T at -65°C to 150°C. Extended temperature range reflects improved semiconductor process technology and thermal design. These parts are suitable for applications requiring operation at elevated ambient or junction temperatures. Standard recovery 1N4006 variants from Micro Commercial Co and Taiwan Semiconductor Corporation operate to 150°C, matching the original part's upper limit.

Q: Is reverse leakage current (Ir) a critical parameter for substitution?

A: Reverse leakage current defines the small reverse current flowing when the diode is reverse-biased. The PR1006GL-T specifies 5 µA at 800 V. Most substitutes maintain this specification. The exception is 1N4006RLG at 10 µA, which is acceptable for general-purpose rectification but may introduce measurable leakage in high-impedance circuits or precision analog applications. For standard power supply and rectification circuits, the difference is negligible.

Q: What inventory considerations apply to substitute selection?

A: PR1006G-T (3100 units) and 1N4006-TP (69,145 units) offer the highest inventory availability. RGP10K-E3/54 (1102 units) and RGP10KE-E3/54 (959 units) provide adequate stock for fast recovery applications. 1N4006RLG (62,255 units) is abundantly available but classified as Not For New Designs. For new production, prioritize active parts with established supply chains: PR1006G-T, 1N4006-TP, or Vishay SUPERECTIFIER® variants.
