Product details
Overview
689-3 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, and 500 ns reverse recovery time - used in high-efficiency AC/DC front-end supplies for industrial power systems.
For engineers reviewing the 689-3 datasheet, 689-3 pinout, 689-3 application, or 689-3 equivalent, key selection criteria include its 300 V working peak reverse voltage, 500 ns trr, 15 A IO rating at 55 °C, thermally robust aluminum package with RθJC = 6.0 °C/W, and RoHS-compliant matte tin terminals.
Technical Context
This device integrates two fast recovery diodes in a single aluminum-cased doubler topology, enabling full-wave rectification without external center-tap transformers. Its controlled avalanche characteristics and 150 A non-repetitive surge capability support transient-heavy industrial line inputs.
Designed for conduction-angle-limited 50/60 Hz sine-wave operation, it delivers 10.5 A average output at 100 °C case temperature and maintains stable reverse leakage (<200 µA at 100 °C) up to VRWM = 300 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 300 V - maximum continuous reverse voltage before breakdown; defines safe AC input peak handling in bridge/doubler topologies |
| IO (TC = 55 °C) | 15 A - average rectified DC output per leg under forced-air-cooled conditions; sets baseline power capacity |
| trr | 500 ns - measured at IF = 1.0 A, IRM = 1.0 A, IR(REC) = 0.5 A; enables efficient switching in high-frequency SMPS auxiliary supplies |
| RθJC | 6.0 °C/W - thermal resistance from junction to case; supports direct heatsink mounting for high-power dissipation |
| TJ max | +150 °C - maximum allowable junction temperature; allows operation in enclosed industrial enclosures with ambient up to +85 °C |
| IFSM | 150 A - non-repetitive surge current rating; withstands inrush currents during cold-start of motor drives and UPS systems |
Pinout & Package
Package: Aluminum case with electrically isolated base, matte tin terminals, weight ≈30 g. Dimensions per RF01151 Rev A: D = 56.9–57.4 mm, E = 47.5–47.75 mm, F = 37.59–37.85 mm, C (dia) = 4.19–4.45 mm.
| Pin/Terminal | Circuit Role | Design Meaning |

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-15EWH03-M3 | TO-247AC package, single-diode, 300 V VRWM, 50 ns trr, 15 A IO - faster but not doubler-configured | Requires external dual-diode layout; lacks integrated isolation and thermal mass of aluminum case | Select when board space permits discrete layout and ultra-fast trr is prioritized over mechanical integration |
| ON Semiconductor MUR1530CT | TO-220AB center-tap dual diode, 300 V VRWM, 60 ns trr, 15 A IO - smaller plastic package, no case isolation | Needs insulating hardware for heatsink mounting; lower surge rating (100 A IFSM vs. 150 A) | Choose for cost-sensitive consumer-grade designs where galvanic isolation is not required |
Compared with VS-15EWH03-M3 and MUR1530CT, the 689-3 uniquely combines doubler topology, electrically isolated aluminum packaging, and 150 A surge capability - making it optimal for ruggedized industrial rectification where thermal management, safety isolation, and transient resilience are co-prioritized.

FAQ
What is the maximum junction temperature rating for the 689-3?
The 689-3 has a maximum junction temperature (TJ) rating of +150 °C, verified per Microsemi RF01151 Rev A specifications. This allows sustained operation in high-ambient industrial environments when paired with appropriate heatsinking. The 689-3's aluminum case and low RθJC of 6.0 °C/W help maintain safe TJ margins even at full 15 A load under convection cooling.
Does the 689-3 support RoHS compliance?
Yes, the 689-3 is RoHS compliant, indicated by the "e3" suffix in its full part number. It uses matte tin terminals instead of tin/lead, meeting EU Directive 2011/65/EU requirements. Microsemi confirms this compliance in the RF01151 datasheet, and the device is suitable for use in environmentally regulated industrial equipment without exemption requests.
What does the "D" in the 689-3 nomenclature signify?
The "D" in 689-3 denotes the doubler terminal configuration - meaning the device contains two fast recovery diodes arranged with shared cathode (+) and shared anode (–) outputs, and two independent AC input terminals (AC1 and AC2). This differs from "P" (center-tap positive) or "N" (center-tap negative) variants, and enables full-wave rectification without a center-tapped transformer.
How is thermal performance characterized for the 689-3?
The 689-3 is characterized with RθJC = 6.0 °C/W (junction-to-case) and RθJA = 20 °C/W (junction-to-ambient). Its aluminum case allows direct bolt-down heatsinking, and derating curves in RF01151 show 10.5 A IO at TC = 100 °C. Unlike plastic-packaged alternatives, the 689-3's metal case provides both thermal conduction and electrical isolation - eliminating insulator pads and reducing thermal interface resistance.
Is the 689-3 pin-compatible with other members of the 681/689 series?
No - while all 681/689 series devices share the same ND aluminum package outline and terminal positions, pin function depends on configuration suffix ("D", "P", or "N"). The 689-3 (doubler) has AC1/AC2/+/- terminals, whereas 689-3P (center-tap positive) has AC/+/- pins. Swapping configurations without PCB revision will cause functional failure; only identical suffix variants are mechanically and electrically interchangeable.
