Product details
Overview
681-2P from Microsemi is a center-tap positive standard recovery rectifier assembly in an electrically isolated aluminum case, rated for 200 V VRWM, 15 A average DC output current at TC = 55 °C, and 150 A non-repetitive surge current. It serves as a high-current AC-to-DC conversion stage in industrial power supplies and welding equipment.
For engineers reviewing the 681-2P datasheet, 681-2P pinout, 681-2P application, or 681-2P equivalent, key selection criteria include its 200 V working peak reverse voltage, 1.2 V forward voltage at 10 A per leg, 150 °C junction temperature rating, thermally robust aluminum package, and center-tap positive terminal configuration.
Technical Context
This device integrates two series-connected diode legs sharing a common center-tap anode (–) and cathodes (+), enabling full-wave rectification with single-ended output polarity. Its standard recovery behavior (no trr spec provided) and controlled avalanche characteristics support rugged operation under repetitive line surges and inductive load switching.
The aluminum case provides electrical isolation and low thermal resistance (RθJC = 6.0 °C/W), allowing direct heatsinking without insulating pads. Terminal plating is RoHS-compliant matte tin, and marking includes "AC", "+", "–", and part number on the body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15EWH02-M3 | Single-diode TO-247 package; 200 V VRWM, 15 A IO, but no center-tap configuration. | Requires external center-tap transformer wiring and two devices for equivalent function. | Select when board space permits discrete layout and thermal management via PCB copper. |

FAQ
What is the maximum working peak reverse voltage (VRWM) of the 681-2P?
The 681-2P has a VRWM of 200 V, confirmed in the part nomenclature table and electrical characteristics section of RF01151 Rev A. This rating defines the maximum continuous reverse voltage the device can block without breakdown and aligns with use in 115 VAC systems with appropriate safety margin. The 681-2P maintains this rating across its full operating temperature range.
Does the 681-2P have a specified reverse recovery time (trr)?
No, the 681-2P does not specify reverse recovery time because it is a standard recovery rectifier, not a fast recovery type. The datasheet explicitly lists trr only for the 689-series (e.g., 689-2P = 500 ns). The 681-2P is intended for line-frequency applications where recovery speed is not critical, and its behavior is characterized by controlled avalanche rather than fast switching.
How is the center-tap configured on the 681-2P?
The 681-2P uses a center-tap positive (P) configuration: the "–" terminal is the shared anode (center tap), while the "+" terminal is the cathode output. The "AC" terminals connect to the transformer secondary ends. This arrangement delivers positive DC output referenced to the center tap, matching conventional full-wave rectifier topologies used in industrial power supplies.
What thermal resistance values apply to the 681-2P?
The 681-2P has RθJC = 6.0 °C/W (junction-to-case) and RθJA = 20 °C/W (junction-to-ambient). These values assume proper mounting to a heatsink with thermal interface material. The low RθJC reflects the aluminum case's superior heat conduction, enabling efficient thermal transfer directly from die to heatsink without insulating barriers.
Is the 681-2P RoHS compliant?
Yes, the 681-2P is RoHS compliant, indicated by the "e3" suffix in its full designation (681-2P(e3)). The terminals are plated with RoHS-compliant matte tin, and the device meets Directive 2011/65/EU requirements. This compliance is verified in the Features section and part nomenclature table of RF01151 Rev A.
