Product details
Overview
689-3D from Microsemi is a fast recovery rectifier assembly in doubler configuration, housed in an electrically isolated aluminum case, rated for 300 V VRWM, 15 A average DC output current at TC = 55 °C, 500 ns reverse recovery time, and 150 A non-repetitive surge current - used in high-reliability AC/DC front-end power conversion stages.
For engineers reviewing the 689-3D datasheet, 689-3D pinout, 689-3D application, or 689-3D equivalent, key selection criteria include VRWM (300 V), trr (500 ns), thermal resistance RθJC (6.0 °C/W), isolation-rated metal package, and center-tap/doubler topology compatibility with industrial SMPS and motor drive rectification.
Technical Context
This device implements a dual-diode doubler configuration with electrically isolated aluminum casing, enabling high-voltage AC input rectification without external heatsink mounting. Its controlled avalanche characteristics and 150 °C junction rating support operation under transient overvoltage and elevated ambient conditions.
The 689-3D delivers 1.2 V forward voltage per leg at 10 A, with reverse leakage limited to 10 µA at 25 °C and 200 µA at 100 °C - optimized for efficiency-critical, thermally constrained power supplies where fast recovery minimizes switching losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 300 V - maximum continuous reverse voltage before breakdown; defines safe AC input peak handling capability |
| IO (TC = 55 °C) | 15 A - max average DC output current with case temperature held at 55 °C; sets baseline conduction capacity |
| trr | 500 ns - time for diode to transition from forward to reverse blocking; critical for high-frequency rectifier efficiency |
| RθJC | 6.0 °C/W - thermal resistance from junction to case; enables direct mounting to heatsink for thermal management |
| IFSM | 150 A - non-repetitive surge current rating; supports inrush and fault-current robustness in power systems |
| VF @ 10 A | 1.2 V per leg - forward voltage drop at rated current; determines conduction loss and heat generation per diode |
Pinout & Package
Package: Aluminum case with electrically isolated terminals; weight ≈30 g; RoHS-compliant matte tin terminations; marking includes "AC", "+", "−", and part number.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery doubler rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15EWH06-M3 | Single-die TO-247 package; 600 V VRWM; 15 A IO; 60 ns trr; no integrated doubler topology | Requires external wiring for doubler function; lacks electrically isolated case | Select when ultra-fast recovery (<100 ns) is prioritized over mechanical integration and isolation |
| IXYS MBR1560CT | TO-220AB package; 60 V VRWM; 15 A IO; Schottky construction; VF = 0.85 V @ 10 A | Lower voltage rating limits use to low-VAC inputs; no avalanche capability or metal-case isolation | Select only for low-voltage, low-loss applications where 300 V VRWM and isolation are not required |
Compared with VS-15EWH06-M3 and MBR1560CT, the 689-3D uniquely combines 300 V VRWM, 500 ns trr, doubler topology, and electrically isolated aluminum packaging - making it irreplaceable for space-constrained, high-isolation, medium-voltage industrial rectification where mechanical robustness and transient immunity are mandatory.

FAQ
What is the maximum working peak reverse voltage (VRWM) for the 689-3D?
The 689-3D has a VRWM of 300 V, corresponding to the "-3" suffix in its nomenclature. This rating is verified per JESD282-B and defines the maximum continuous reverse voltage the device can block without breakdown under normal operating conditions - critical for ensuring safe operation with 230 VAC or 400 VAC line-derived inputs.
Does the 689-3D have a center tap or doubler configuration?
The 689-3D uses a doubler configuration, indicated by the "D" suffix in its part number. It features two AC input terminals (AC1 and AC2), one common cathode (+), and one common anode (−), enabling full-wave voltage doubling without external diodes - distinct from center-tap variants like 689-3P or 689-3N.
What is the thermal resistance from junction to case (RθJC) for the 689-3D?
The 689-3D has a specified RθJC of 6.0 °C/W, measured under standard test conditions. This low thermal resistance enables efficient heat transfer from the silicon die to the aluminum case, allowing direct mounting to a heatsink - a key enabler for high-power density designs where forced-air cooling is impractical.
Is the 689-3D RoHS compliant?
Yes, the 689-3D is RoHS compliant, as confirmed by the "e3" suffix in its full designation (689-3D(e3)). Its terminations use matte tin plating instead of tin/lead, meeting EU Directive 2011/65/EU requirements - verified in Microsemi's official documentation and supported by traceable material declarations.
What is the reverse recovery time (trr) specification for the 689-3D?
The 689-3D has a reverse recovery time of 500 ns, measured at IF = 1.0 A, IRM = 1.0 A, and IR(REC) = 0.5 A per leg. This value is specified in the RF01151 datasheet and reflects the device's fast recovery performance - essential for minimizing switching losses and EMI in medium-frequency (20–100 kHz) power conversion topologies.
