Product details
Overview
D5G-T from Diodes Incorporated is a 1.0A glass passivated general-purpose rectifier diode with 600V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 1.0A, and 30A non-repetitive surge current capability; used in AC/DC front-end rectification for industrial power supplies and auxiliary power rails.
For engineers reviewing the D5G-T datasheet, D5G-T pinout, D5G-T application, or D5G-T equivalent, key selection criteria include VRRM rating for input voltage margin, thermal resistance (100°C/W) for heatsink-limited layouts, trr of 2.0µs for moderate-switching SMPS inputs, and T-1 package compatibility with through-hole board assembly.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60Hz line frequency. Its glass passivated junction ensures stable leakage performance across -65°C to +150°C operating range and supports derated operation under capacitive loading.
Thermal design relies on lead-to-ambient conduction (RθJA = 100°C/W) with specified mounting per J-STD-020 Level 1 moisture sensitivity. Reverse recovery time (trr = 2.0µs) and low junction capacitance (CT = 8.0pF at 4V) enable use in low-noise, medium-frequency rectification without snubber circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands 600V peak reverse voltage, suitable for 400VAC mains-derived inputs with safety margin. |
| IO @ 75°C | 1.0 A - Continuous average forward current rating at 75°C ambient, requires thermal management above that temperature. |
| VFM @ 1.0A | 1.0 V - Forward drop determines conduction loss (1.0W max at full load), impacting efficiency and thermal design. |
| IFSM | 30 A - Surge rating supports inrush current handling during cold-start of power supplies without failure. |
| trr | 2.0 µs - Fast recovery enables use in 20–50kHz line-frequency rectifiers without excessive switching loss or EMI. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance defines required PCB copper area or heatsinking for safe operation. |
Pinout & Package
Package: T-1 molded plastic case (UL 94V-0), axial leaded, cathode band marked, 0.13g weight. Dimensions: A = 25.4mm (length), B = 2.6–3.2mm (diameter), D = 2.2–2.6mm (lead diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to AC input or transformer secondary; must withstand full surge current and reverse voltage stress. |
| Cathode | Forward current exit / DC output node | Connected to bulk capacitor or downstream regulator; polarity marking (band) prevents reverse installation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable IR leakage (<5µA at 25°C, <50µA at 100°C) and long-term reliability in humid environments. |
| Lead-free, RoHS-compliant finish | Tin-plated leads meet MIL-STD-202 solderability requirements and support lead-free reflow or hand-soldering. |
| High surge rating (30A) | Survives repeated cold-start surges in unregulated AC/DC adapters and industrial control power modules. |
| Low junction capacitance (8.0pF) | Minimizes high-frequency coupling noise into sensitive analog or communication circuitry sharing same ground plane. |
Applications
| Industrial AC/DC Power Supply | LED Driver Auxiliary Rectification |
|---|---|
Use Scenario: Full-wave bridge input stage in 24V/48V industrial power supplies accepting 85–264VAC input. IC Role / Device Role / Timing Role: General-purpose rectifier converting AC line to unregulated DC bus prior to buck or flyback regulation. Use Value: 600V VRRM provides 2× margin over 264VAC peak (373V), ensuring robustness against line transients and brownouts. | Use Scenario: Low-current auxiliary supply for gate drivers or bias rails in constant-current LED driver modules. IC Role / Device Role / Timing Role: Half-wave rectifier feeding small electrolytic capacitor to generate isolated 12–15V bias rail. Use Value: 1.0V VFM minimizes dropout in low-power auxiliary paths, preserving headroom for LDO or linear regulator input. |
| Appliance Control Board Power | Smart Meter AC Sensing Interface |
Use Scenario: Mains-powered control boards in washing machines, HVAC controllers, and PLC I/O modules. IC Role / Device Role / Timing Role: Primary rectifier for logic supply generation, often paired with Zener or IC regulator. Use Value: T-1 axial package allows manual insertion and wave soldering; 100°C/W RθJA supports natural convection cooling in enclosed enclosures. | Use Scenario: Voltage divider and rectification stage in anti-tamper or zero-crossing detection circuits of utility meters. IC Role / Device Role / Timing Role: Precision half-wave rectifier feeding comparator or microcontroller ADC input. Use Value: 2.0µs trr ensures accurate zero-crossing timing with minimal phase lag; low CT reduces capacitive coupling error in sensing nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007-T | Same 1.0A/1000V rating but higher VFM (1.1V) and slower trr (30µs); epoxy passivation instead of glass. | Less suitable for higher-frequency or thermally constrained designs due to higher loss and slower recovery. | Select when cost is primary and 60Hz-only operation with generous thermal margin is acceptable. |
| ES1J | Surface-mount SMA package; 1.0A/600V; faster trr (35ns); higher VFM (1.7V); lower RθJA (50°C/W). | Requires SMT layout; better for compact, high-efficiency designs where board space and thermal performance outweigh through-hole assembly needs. | Select for automated assembly, improved thermal performance, or higher switching frequency compatibility. |
Compared with 1N4007-T, D5G-T offers superior thermal stability and faster recovery for margin-critical or moderately switched applications; versus ES1J, it trades SMT efficiency for through-hole serviceability and lower forward loss in legacy designs.

FAQ
What is the maximum allowable ambient temperature for continuous 1.0A operation?
The D5G-T is rated for 1.0A average forward current at TA = 75°C. Operation above this requires derating per Figure 1 in DS29001: at 100°C ambient, IO drops to ~0.75A; at 125°C, it falls to ~0.5A. Thermal design must ensure junction temperature stays ≤150°C.
Can D5G-T be used in full-wave bridge configurations?
Yes - D5G-T is commonly used as one leg of a discrete full-wave bridge (e.g., four D5G-T devices). Its 600V VRRM and 30A IFSM support standard 230VAC bridge operation. Ensure matched thermal layout across all four diodes to avoid current imbalance and premature failure.
Is the T-1 package compatible with wave soldering processes?
Yes - the T-1 package uses tin-plated leads compliant with MIL-STD-202 Method 208 and rated for both wave and hand soldering. The UL 94V-0 molded plastic body withstands typical wave solder temperatures (≤260°C for ≤10 seconds), provided lead spacing and board thermal mass are within specification limits.
How does reverse recovery time affect EMI in rectifier applications?
With trr = 2.0µs, D5G-T exhibits low reverse recovery charge (Qrr ≈ 0.02µC estimated), reducing high-frequency ringing and conducted EMI during turn-off. This makes it suitable for EMI-sensitive applications like smart meters and industrial controls where filtering complexity must be minimized.
