Product details
Overview
DF1506M from Diodes Incorporated is a 1.5A glass passivated bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 1.1V forward voltage drop at 1.5A, and 50A non-repetitive surge capability - designed for AC/DC conversion in compact PCB-mounted power supplies.
For engineers reviewing the DF1506M datasheet, DF1506M pinout, DF1506M application, or DF1506M equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (40°C/W) on standard 13×13mm copper pads, and UL recognition (E94661) for safety-critical industrial power entry designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a DF-M molded plastic package with tin-plated terminals. It operates across –65°C to +150°C and delivers 1.5A average output current at 40°C ambient, derated linearly to zero at 140°C per Fig. 1.
Its 25pF typical junction capacitance (measured at 1MHz, 4V reverse bias) and low 10µA peak reverse leakage at 25°C support stable operation in line-frequency rectification without high-frequency switching noise coupling. The 10.4A²s I²t rating ensures robustness against 8.3ms half-sine surges up to 50A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600V - Withstands transient line spikes up to 600V without breakdown in AC mains input stages. |
| IO @ TA=40°C | 1.5A - Continuous DC output current achievable with 13×13mm PCB copper area and no forced airflow. |
| VFM @ IF=1.5A | 1.1V - Total forward drop across two series diodes in conduction path; determines conduction loss (1.65W max at full load). |
| IFSM | 50A - Survives cold-start inrush into bulk capacitors under 8.3ms half-sine waveform per UL/IEC standards. |
| RθJA | 40°C/W - Junction-to-ambient thermal resistance measured on standard FR-4 with specified copper land; enables thermal design without heatsink below ~1W dissipation. |
| CT @ 1MHz | 25pF - Low junction capacitance minimizes EMI generation and avoids resonance issues in EMI filter design. |
Pinout & Package
DF1506M uses the DF-M surface-mount package (7.4–7.9mm × 6.2–6.5mm × 2.4–3.4mm height), molded in UL 94V-0 plastic with tin-plated leads. Polarity is marked on case; terminals are arranged as standard bridge configuration: AC1, AC2, +, –.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One leg of AC input; connects to live or neutral depending on board layout; symmetrical with AC2. |
| AC2 | Input AC terminal 2 | Second leg of AC input; forms full-wave input pair with AC1; interchangeable in ungrounded applications. |
| + | Positive DC output | Anode of internal upper diodes; delivers rectified positive voltage to bulk capacitor or regulator input. |
| – | Negative DC output / return | Cathode of internal lower diodes; serves as circuit common/reference return path for downstream DC stages. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable long-term reliability under humidity and thermal cycling without hermetic sealing. |
| UL Recognized Component (E94661) | Validates compliance with UL 60950-1/62368-1 for end-equipment safety certification without additional component-level testing. |
| Lead-free & RoHS compliant (Date Code 0532+) | Meets EU RoHS Directive 2011/65/EU with exemptions applied; suitable for lead-free reflow assembly. |
| Moisture Sensitivity Level 1 | No baking required prior to SMT reflow; eliminates production delay and moisture-related popcorning risk. |
Applications
| Industrial AC/DC Power Supplies | Appliance Motor Control Boards |
|---|---|
Use Scenario: Mains-powered control boards in washing machines, dishwashers, and HVAC fan modules requiring reliable 5–24V DC rails. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion stage delivering isolated low-voltage DC for microcontrollers, relays, and gate drivers. Use Value: 600V VRRM accommodates 230VAC ±10% with margin; 50A IFSM handles motor startup surges without degradation. | Use Scenario: Compact embedded power sections in smart home devices (e.g., coffee makers, air purifiers) with space-constrained PCB layouts. IC Role / Device Role / Timing Role: Surface-mount bridge rectifier replacing discrete diode solutions to reduce footprint and assembly cost. Use Value: DF-M package (7.7×6.35mm) saves >40% board area vs. traditional KBP/DIP packages while maintaining 1.5A rating. |
| LED Driver Input Stages | Industrial Sensor Transmitter Modules |
Use Scenario: Constant-current LED drivers for commercial lighting operating directly from 120/230VAC inputs. IC Role / Device Role / Timing Role: Front-end rectification before PFC or buck converter; must withstand line transients and sustain continuous conduction. Use Value: 1.1V VFM limits conduction loss to ≤1.65W at full load, reducing thermal stress on adjacent ICs and enabling smaller heatsinks. | Use Scenario: 4–20mA loop-powered sensor transmitters deployed in factory automation with wide ambient temperature range. IC Role / Device Role / Timing Role: Mains-derived auxiliary supply for analog front-end and signal conditioning circuitry. Use Value: –65°C to +150°C operating range ensures functionality in unheated enclosures or high-temperature industrial zones. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 600V VRRM and 1.5A IO, but GBU package (10.3×10.3mm) is larger; RθJA = 45°C/W. | Less space-efficient; requires larger PCB cutout and more copper area for equivalent thermal performance. | Select when legacy GBU footprint compatibility is required or higher surge margin (60A IFSM) is needed. |
| MB156 (Comchip) | 600V VRRM, 1.5A IO, MB-11 package (7.1×6.2mm); VFM = 1.05V; RθJA = 42°C/W. | Nearly identical footprint and thermal profile; slightly lower forward drop improves efficiency by ~50mW at 1.5A. | Prefer for new designs where marginal efficiency gain and exact size match justify qualification of alternate source. |
Compared with GBU6K and MB156, DF1506M offers the lowest profile (max 3.4mm height) and UL recognition out-of-box, making it optimal for ultra-thin industrial power modules where safety certification time and vertical clearance are critical constraints.

FAQ
Is DF1506M suitable for capacitive-input filter applications?
Yes, but with 20% current derating per datasheet guidance. At 1.5A rated IO, maximum continuous current drops to 1.2A when feeding a bulk capacitor input. This accounts for increased RMS current and thermal stress caused by narrow conduction angles in such topologies.
What is the minimum recommended PCB copper area for thermal management?
The datasheet specifies thermal resistance RθJA = 40°C/W when mounted on 13×13mm (0.03mm thick) copper land areas per terminal. Reducing copper area increases thermal resistance nonlinearly; halving the area raises RθJA to approximately 65°C/W, limiting safe IO to ~0.9A at 40°C ambient.
Does DF1506M require pre-baking before reflow soldering?
No. DF1506M is rated Moisture Sensitivity Level 1 per J-STD-020C, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking - eliminating process steps and moisture-related defects like popcorn cracking.
Can DF1506M replace DF1504M in an existing design?
Yes, with full pin and functional compatibility. DF1506M substitutes DF1504M (400V VRRM) while raising peak reverse voltage to 600V - improving surge margin and enabling use in 230VAC regions with higher line tolerance. No layout or firmware changes are needed.
