Product details
Overview
689-6 from Microsemi is a fast recovery rectifier assembly in doubler configuration, housed in an electrically isolated aluminum case. It delivers 15 A average DC output current at TC = 55 °C, supports 600 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 conversion for industrial motor drives.
For engineers reviewing the 689-6 datasheet, 689-6 pinout, 689-6 application, or 689-6 equivalent, key selection criteria include its 600 V working peak reverse voltage, 500 ns trr, aluminum-case thermal performance (RθJC = 6.0 °C/W), and RoHS-compliant matte tin terminals - critical for high-temp, high-surge industrial power supplies.
Technical Context
This device integrates two fast recovery diodes in a single aluminum package configured as a voltage doubler, enabling dual-phase rectification without external interconnection. Its controlled avalanche characteristics and 150 A non-repetitive surge rating support robust operation during line transients and inductive load switching.
The thermally optimized metal case provides direct heatsink mounting and achieves RθJC = 6.0 °C/W, while RθJA = 20 °C/W reflects natural convection limits. Terminal marking includes AC (AC input), + (cathode-positive output), and – (anode-negative) per mechanical drawing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 600 V - maximum continuous reverse voltage before breakdown; defines safe operating margin in 400–480 VAC systems with transient headroom |
| trr | 500 ns - reverse recovery time at IF = 1.0 A, IRM = 1.0 A; enables efficient high-frequency rectification up to ~200 kHz |
| IO @ TC = 55 °C | 15 A - average DC output current per leg; requires heatsinking above ambient to maintain junction ≤150 °C |
| RθJC | 6.0 °C/W - thermal resistance from junction to case; enables direct mounting to heatsink for high-power dissipation |
| IFSM | 150 A - non-repetitive surge current capability; withstands inrush and short-circuit events in motor drive DC links |
| VF @ 10 A | 1.2 V - forward voltage drop per leg; determines conduction loss of ~12 W total at 10 A full-load |
| TJ max | 150 °C - maximum junction temperature; sets upper limit for thermal design and derating curves |

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-68906 | Same 600 V VRWM, 500 ns trr, but TO-247AC package with lower IFSM (120 A) and higher RθJC (1.2 °C/W for single die vs. 6.0 °C/W for dual-die aluminum case) | Requires external heatsinking and isolation; less suited for high-surge, high-temperature environments | Select 689-6 when aluminum-case thermal mass and 150 A surge tolerance are required |
| IXYS MBR6060CT | 60 V VRWM, 60 A IO, TO-247 package - not voltage-compatible; faster trr (35 ns) but unsuitable for 600 V systems | Designed for low-voltage, high-current SMPS; incompatible with 400–480 VAC inputs | Not a functional alternative; only consider if system voltage is reduced to ≤70 V DC |
Compared with VS-68906 and MBR6060CT, the 689-6 uniquely combines 600 V rating, 150 A surge capability, and integrated aluminum heatsink - making it irreplaceable in high-reliability, high-temperature industrial rectification where thermal inertia and transient immunity are design-critical.

FAQ
What is the maximum junction temperature specification for the 689-6?
The 689-6 has a maximum junction temperature (TJ) of +150 °C, as confirmed in the Absolute Maximum Ratings table on page 1 of RF01151 Rev A. This rating enables operation in high-ambient industrial enclosures. Thermal design must ensure that actual junction temperature remains below this limit using the specified RθJC = 6.0 °C/W and appropriate heatsinking. The 689-6 must not be operated beyond this absolute maximum, even momentarily.
Does the 689-6 support RoHS-compliant manufacturing processes?
Yes, the 689-6 is an e3-suffixed part, indicating RoHS-compliant matte tin terminals per the part nomenclature table on page 2 of RF01151 Rev A. It supports lead-free reflow soldering at 260 °C for 10 seconds, and all materials comply with Directive 2011/65/EU. The 689-6 does not contain lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE - verified by Microsemi's material declarations.
What does the "D" suffix mean in the 689-6 part number?
The "D" in the 689-6 part number denotes "Doubler" terminal configuration, as defined in the PART NOMENCLATURE section on page 2 of RF01151 Rev A. In this configuration, the device contains two fast recovery diodes arranged to provide dual-polarity DC output from a single AC input - distinct from "P" (center tap positive) or "N" (center tap negative). The 689-6 uses AC, +, and – terminals accordingly.
How is thermal performance characterized for the 689-6?
The 689-6 specifies RθJC = 6.0 °C/W (junction-to-case) and RθJA = 20 °C/W (junction-to-ambient) under natural convection, per the MAXIMUM RATINGS table on page 1 of RF01151 Rev A. Its aluminum case is designed for direct bolt-down heatsinking. Derating curves on page 5 confirm 15 A IO at TC = 55 °C, dropping to 10.5 A at TC = 100 °C. No thermal pad or insulator is needed due to electrical isolation.
Is the 689-6 pinout compatible with standard TO-247 or TO-220 packages?
No, the 689-6 uses a proprietary ND aluminum package with three terminals (AC, +, –) arranged per the PACKAGE DIMENSIONS on page 6 of RF01151 Rev A - not pin-compatible with TO-247 or TO-220 footprints. Its terminals are spaced for direct heatsink mounting and lack plastic body or standard leadframe geometry. PCB layout must follow Microsemi's mechanical drawing; no adapter or socket is defined for legacy packages.
