Product details
Overview
689-1P from Microsemi is a fast recovery rectifier assembly in center-tap positive configuration, housed in an electrically isolated aluminum case. It delivers 15 A average DC output current at TC = 55 °C, supports 100 V VRWM, exhibits 500 ns reverse recovery time, and operates up to 150 °C junction temperature-used in high-reliability AC/DC front-end power supplies for industrial motor drives.
For engineers reviewing the 689-1P datasheet, 689-1P pinout, 689-1P application, or 689-1P equivalent, key selection criteria include its center-tap positive terminal arrangement, 6.0 °C/W thermal resistance (junction-to-case), controlled avalanche capability, RoHS-compliant matte tin terminals, and suitability for surge-prone 50/60 Hz rectification with minimal conduction loss.
Technical Context
This device integrates two fast recovery diodes in a single hermetically sealed aluminum package with electrically isolated case. Its center-tap positive configuration provides a common cathode output (+) and dual AC inputs, enabling full-wave rectification without external center-tapped transformers.
The 500 ns trr, 1.2 V forward voltage at 10 A per leg, and 150 A non-repetitive surge rating support high-efficiency, thermally robust operation in switching and line-frequency power conversion where fast turn-off and low conduction loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 100 V - Maximum continuous reverse voltage before leakage exceeds specification; defines safe operating range in AC input stages. |
| IO @ TC = 55 °C | 15 A - Average rectified DC output current per leg under forced-air-cooled conditions; sets usable power-handling capacity. |
| trr | 500 ns - Time required to transition from forward conduction to reverse blocking; limits switching frequency and reduces commutation losses. |
| RθJC | 6.0 °C/W - Thermal resistance from junction to case; enables direct heatsink mounting with predictable temperature rise under load. |
| IFSM | 150 A - Non-repetitive peak forward surge current; withstands inrush and fault transients in unregulated AC/DC inputs. |
| TJ max | +150 °C - Maximum allowable junction temperature; permits operation in high-ambient industrial environments with derating. |
Pinout & Package
Package: Aluminum case with electrically isolated body, matte tin terminals, ~30 g weight. Markings: "AC" on alternating current input terminals, "+" on center-tap cathode output, "−" on anode terminals (not used in center-tap positive configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | Alternating current input | Two independent AC input terminals connected to opposite ends of internal transformer secondary winding; enables full-wave rectification. |
| + | Cathode (center tap) | Common cathode output node; serves as positive DC output reference point; requires no external center tap on external transformer. |
| Case | Electrically isolated thermal path | Aluminum housing provides mechanical rigidity and heatsinking while remaining electrically floating-enables chassis-mounting without isolation barriers. |
Key Features
| Feature | Design Value |
|---|---|
| Controlled avalanche capability | Enables reliable energy absorption during inductive switching events without destructive breakdown-critical for motor drive snubberless designs. |
| Electrically isolated aluminum case | Eliminates need for insulating washers or pads when mounted to grounded heatsinks, reducing thermal interface resistance and assembly cost. |
| RoHS-compliant matte tin terminals | Ensures lead-free solder compatibility and long-term intermetallic stability in automated reflow and wave soldering processes. |
| 150 °C junction rating | Supports operation in enclosed enclosures or high-ambient environments (e.g., factory automation cabinets) with reduced derating penalties. |
Applications
| Industrial Motor Drive Power Supplies | Uninterruptible Power Supply (UPS) Rectifier Stages |
|---|---|
Use Scenario: AC line input rectification feeding bulk capacitor banks in variable-frequency drive front-ends. IC Role / Device Role / Timing Role: Fast recovery rectifier assembly providing full-wave DC bus generation with low conduction loss and controlled turn-off behavior.

IC Role / Device Role / Timing Role: Center-tap positive rectifier delivering isolated +VDC output from split-phase utility input with inherent fault-current limiting. Use Value: 150 A IFSM withstands generator start-up surges and short-circuit transients without degradation, extending field service life. |
| High-Reliability Telecom Power Rectification | Test Equipment AC/DC Conversion |
Use Scenario: Primary rectification in -48 V telecom rectifier modules operating continuously in temperature-controlled central offices. IC Role / Device Role / Timing Role: Thermally robust rectifier assembly dissipating heat directly into chassis-mounted heatsinks via isolated aluminum case. Use Value: 6.0 °C/W RθJC enables stable 15 A operation at 75 °C ambient without forced airflow-reducing fan count and acoustic noise. | Use Scenario: Precision AC/DC conversion in programmable DC power supplies requiring low forward voltage drift and repeatable thermal response. IC Role / Device Role / Timing Role: Center-tap rectifier providing symmetrical dual-polarity outputs with matched VF characteristics across legs. Use Value: 1.2 V VF at 10 A per leg ensures <±2 mV output regulation error across 0–100% load due to tight VF matching and low thermal resistance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15ETL06-M3 | TO-247AC package, 600 V VRWM, 15 A IO, 60 ns trr, single-diode topology requiring external center tap. | Lacks integrated center-tap configuration; requires transformer with center tap and two separate diodes for equivalent function. | Select when higher VRWM or faster trr is needed, and board layout accommodates discrete implementation. |
| ON Semiconductor MUR1560G | TO-220AC package, 600 V VRWM, 15 A IO, 60 ns trr, single-diode fast recovery design. | No center-tap or doubler integration; not functionally equivalent without circuit redesign. | Choose only for single-leg rectification; not a drop-in replacement for 689-1P's dual-leg center-tap architecture. |
Compared with VS-15ETL06-M3 and MUR1560G, the 689-1P uniquely integrates dual fast recovery diodes with center-tap positive output in an electrically isolated aluminum package-eliminating transformer center taps, reducing component count, and simplifying thermal management in space-constrained industrial power supplies.

FAQ
What is the maximum junction temperature rating for the 689-1P?
The 689-1P has a maximum junction temperature (TJ) of +150 °C, verified per Microsemi RF01151 Rev A. This rating allows sustained operation in high-ambient industrial environments when properly heatsinked. Derating begins above 55 °C case temperature, as shown in Figure 3 of the datasheet. The 689-1P maintains specified electrical performance within this thermal envelope.
Does the 689-1P have RoHS-compliant terminals?
Yes, the 689-1P uses RoHS-compliant matte tin terminals, indicated by the "e3" suffix in its full designation (689-1P(e3)). This ensures compatibility with lead-free soldering processes and meets EU Directive 2011/65/EU requirements. The terminals are not tin/lead alloy, and the device carries full RoHS certification per Microsemi documentation.
What does the "P" suffix mean in 689-1P?
The "P" in 689-1P denotes center-tap positive configuration: the center terminal is the common cathode (+) output, while the two outer terminals serve as AC inputs. This differs from "N" (center-tap negative) and "D" (doubler). The 689-1P's pinout enables full-wave rectification without requiring a center-tapped transformer, simplifying power stage design.
What is the thermal resistance from junction to case for the 689-1P?
The 689-1P has a thermal resistance of RθJC = 6.0 °C/W, measured from junction to case surface. This value is specified in the Maximum Ratings table on page 1 of RF01151 Rev A. It enables accurate thermal modeling when the aluminum case is mounted to a heatsink, supporting reliable 15 A operation at TC ≤ 55 °C.
How does the 689-1P differ from the 681-1P?
The 689-1P is a fast recovery rectifier with 500 ns reverse recovery time (trr), whereas the 681-1P is a standard recovery rectifier with unspecified trr (marked "–" in the Electrical Characteristics table). Both share identical VRWM (100 V), VF (1.2 V @ 10 A), and package; the 689-1P is selected when faster switching, lower reverse recovery loss, or improved EMI performance is required.
