Product details
Overview
1N6479-E3/96 from Vishay General Semiconductor is a surface-mount glass-passivated junction rectifier in the Superectifier® family, configured as a single discrete diode with 100 V maximum repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 1.1 V forward voltage drop at 1.0 A and 25 °C. It is used for general-purpose rectification in power supplies and freewheeling applications in automotive and telecom systems.
For engineers reviewing the 1N6479-E3/96 datasheet, 1N6479-E3/96 pinout, 1N6479-E3/96 application, or 1N6479-E3/96 equivalent, key selection criteria include its DO-213AB (GL41) package, 30 A surge rating, 10 μA reverse leakage at 25 °C, 175 °C max junction temperature, and RoHS-compliant matte tin-plated leads.
Technical Context
This standard-recovery rectifier features a glass-passivated PN junction housed in a molded epoxy GL41 (DO-213AB) case rated to UL 94 V-0. Its polarity is marked by two bands: white (first band, device type) and red (second band, 100 V VRRM rating).
Designed for automated placement and high-reliability operation, it delivers low forward voltage (1.1 V @ 1 A, 25 °C), low leakage (10 μA @ 25 °C), and high surge capability (30 A IFSM, 8.3 ms half-sine). Thermal resistance is 50 °C/W junction-to-ambient (RθJA) on 6.0 mm × 6.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage, defines safe AC/DC input voltage headroom |
| IF(AV) | 1.0 A - continuous DC forward current rating at TA = 75 °C, determines steady-state power handling |
| VF | 1.1 V @ 1.0 A, 25 °C - forward conduction loss directly impacts efficiency and thermal design |
| IR | 10 μA @ 25 °C - low reverse leakage preserves isolation integrity in high-impedance circuits |
| IFSM | 30 A @ 8.3 ms - surge withstand capability protects against inrush and transient overloads |
| TJ max. | 175 °C - extended junction temperature range supports operation in under-hood or enclosed industrial environments |
| CJ | 8.0 pF @ 4.0 V, 1 MHz - low junction capacitance minimizes switching noise in rectifier and snubber paths |
Pinout & Package
Package: GL41 (DO-213AB) - hermetically sealed glass-body surface-mount package with matte tin-plated leads, MSL Level 1 compliant (peak reflow 250 °C), UL 94 V-0 rated epoxy molding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of source; must be routed with adequate copper area for thermal dissipation |
| Cathode | Forward current exit point / reverse-blocking terminal | Marked by dual color bands (white + red); ties to output or return path; polarity-critical for rectification direction |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Enhanced reliability via glass passivation, reducing surface leakage and improving long-term stability under thermal cycling |
| Low VF (1.1 V) | Reduces conduction losses by ~15% vs. typical 1 A rectifiers, lowering heatsink requirements in compact power supplies |
| MSL Level 1 rating | Enables direct use in standard SMT reflow without dry-pack or baking, simplifying manufacturing logistics |
| 30 A IFSM surge rating | Withstands repeated cold-start surges in 12 V automotive systems and unregulated DC inputs without degradation |
| DO-213AB mechanical robustness | Stable lead geometry and glass-body construction resist solder joint fatigue in vibration-prone environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4004-G | Higher VF (1.1 V @ 1 A same), but TO-220 package; 400 V VRRM; no MSL Level 1 rating | Through-hole assembly only; unsuitable for automated SMT lines or space-constrained PCBs | Select when legacy through-hole layout exists and higher VRRM margin is required |
| SS14-E3/5AT | Schottky architecture; VF = 0.5 V @ 1 A; 40 V VRRM; 125 °C TJ max; same DO-214AC package footprint | Lower loss but limited to ≤40 V systems; not suitable for 100 V reverse blocking | Select for ultra-low-loss 24 V or 36 V DC-DC outputs where reverse voltage stays below 40 V |
Compared with 1N6479-E3/96, 1N4004-G offers higher voltage rating but lacks SMT compatibility and moisture sensitivity compliance, while SS14-E3/5AT reduces conduction loss significantly but sacrifices reverse voltage capability and thermal ceiling-making each alternative situationally optimal based on voltage, assembly, and thermal constraints.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N6479-E3/96?
The 1N6479-E3/96 has a VRRM of 100 V, confirmed in the Vishay datasheet Document Number 88527. This rating defines the highest instantaneous reverse voltage the diode can block repeatedly without breakdown. It is marked by the red second band on the GL41 package and distinguishes it from adjacent variants like 1N6478 (50 V) and 1N6480 (200 V).
Does the 1N6479-E3/96 meet moisture sensitivity level (MSL) requirements for standard SMT reflow?
Yes, the 1N6479-E3/96 meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 250 °C. This allows direct placement onto PCBs without dry-packaging or baking, supporting high-throughput automated assembly. The GL41 package's glass body and epoxy encapsulation contribute to this robust moisture resistance.
What is the forward voltage drop (VF) of the 1N6479-E3/96 at operating conditions?
The 1N6479-E3/96 exhibits a VF of 1.1 V at 1.0 A and 25 °C, per the Vishay datasheet. At 75 °C, VF drops to 1.0 V due to semiconductor physics. This low conduction loss improves power conversion efficiency and reduces thermal stress compared to higher-VF alternatives in 1 A rectifier applications.
How is polarity identified on the 1N6479-E3/96 package?
Polarity is indicated by two axial color bands on the 1N6479-E3/96: the first (white) denotes the Superectifier® device type, and the second (red) specifies the 100 V VRRM rating. The banded end is the cathode. This dual-band system replaces traditional single-bar marking and enables rapid visual identification during manual inspection and automated optical sorting.
What is the junction-to-ambient thermal resistance (RθJA) for the 1N6479-E3/96?
The 1N6479-E3/96 has an RθJA of 50 °C/W when mounted on 0.24" × 0.24" (6.0 mm × 6.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This value assumes standard JEDEC test conditions and guides PCB layout decisions-larger copper areas or thermal vias can further reduce effective thermal resistance in real-world designs.
