Product details
Overview
DBF210 from Diodes Incorporated is an obsolete 2A surface-mount bridge rectifier with 1000V peak repetitive reverse voltage, 1.0V max forward voltage at 2A, and 5μA max leakage current at 1000V/25°C, used for AC–DC full-wave rectification in SMPS, LED lighting drivers, and battery chargers.
For engineers reviewing the DBF210 datasheet, DBF210 pinout, DBF210 application, or DBF210 equivalent, key selection considerations include its DBF package thermal resistance (RθJC = 10°C/W), 70A non-repetitive surge rating, RoHS- and halogen-free compliance, and obsolescence status requiring migration to MSB22ML.
Technical Context
The DBF210 integrates four silicon diodes in a single-phase bridge configuration with glass-passivated die construction. It delivers full-wave rectification without external interconnects, supporting capacitive-input filter designs when derated by 20%.
Its thermal design relies on low RθJC (10°C/W) and RθJA (50°C/W) values measured on standardized PCB pads. The device operates across –55°C to +150°C and sustains 20.34 A²s I²t fusing energy under 8.3ms half-sine surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - blocks up to 1000V reverse voltage in each diode leg, enabling use in 700V RMS line applications |
| IO | 2.0 A @ TC = +110°C - continuous average output current rating with heatsink-assisted case temperature control |
| VF | 1.0 V max @ IF = 2A, TA = +25°C - limits conduction loss to ≤2W per bridge at full load |
| IR | 5 μA max @ VR = 1000V, TA = +25°C - ensures minimal standby power loss in high-impedance DC bus hold-up stages |
| IFSM | 70 A peak @ 8.3ms - withstands inrush surges from cold-started capacitive loads without failure |
| RθJC | 10 °C/W - enables direct thermal coupling to metal-core PCB or heatsink for sustained 2A operation |
Pinout & Package
Package: DBF - miniature molded plastic surface-mount package (UL 94V-0), dimensions 6.45–6.85 mm × 8.50–8.90 mm × 1.30–1.50 mm, weight ≈0.214 g, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One of two alternating-current input nodes; marked with polarity symbol on body |
| AC2 | Input AC terminal 2 | Second AC input node; opposite phase to AC1 in full-wave bridge topology |
| +DC | Positive DC output | Anode of internal output diodes; connects to bulk capacitor positive rail |
| –DC | Negative DC output | Cathode of internal output diodes; serves as circuit ground reference point |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability under humidity and thermal cycling stress in consumer-grade power supplies |
| 70A surge rating | Supports robust cold-start behavior in offline SMPS with large input X-capacitors |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and automotive green-material requirements without compromising solderability |
| Miniature DBF footprint | Reduces board area by >30% vs. traditional KBP/SKB packages while maintaining thermal performance |
Applications
| LED Lighting Driver | USB-C PD Adapter |
|---|---|
Use Scenario: AC input rectification stage in constant-current LED driver for commercial downlights. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 90–264V AC to pulsating DC prior to PFC and DC–DC conversion. Use Value: Low VF (≤1.0V) minimizes conduction loss at 2A peak, improving efficiency in thermally constrained aluminum-core PCBs. | Use Scenario: Input-stage rectification in compact 65W USB-C power adapter with active clamp flyback topology. IC Role / Device Role / Timing Role: Primary-side AC–DC conversion element feeding 400V bulk capacitor bank. Use Value: 70A IFSM rating handles inrush surges from 100nF–1μF X-capacitors during plug-in events without degradation. |
| Home Appliance Power Supply | Telecom Wall Adapter |
Use Scenario: Standby and main power supply in smart washing machine control board. IC Role / Device Role / Timing Role: Bridge rectifier supplying unregulated DC to auxiliary LDO and primary PWM controller IC. Use Value: 5μA IR at 1000V ensures <1mW standby dissipation, meeting Energy Star Level VI requirements. | Use Scenario: AC–DC front-end in Class II telecom wall adapter powering VoIP phones and small base stations. IC Role / Device Role / Timing Role: Isolated rectification stage delivering 12V/2A output via flyback transformer secondary. Use Value: DBF package's 10°C/W RθJC allows direct mounting to copper pour, eliminating need for discrete heatsinks in space-constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSB22ML | Successor part: same DBF package, 1000V VRRM, 2A IO, but improved VF (0.95V typ @ 2A) and lower IR (1μA @ 1000V) | Drop-in replacement with enhanced efficiency and lower leakage; qualified for industrial temp range only (–40°C to +125°C) | Select MSB22ML for new designs requiring active support and tighter leakage spec |
| GAB22 | Same ratings (1000V/2A), but in GBU package (larger, through-hole); VF = 1.1V max @ 2A, IR = 5μA @ 1000V | Requires PCB redesign due to through-hole mounting and 12.7mm × 18.3mm footprint; higher thermal resistance (RθJA = 40°C/W) | Consider GAB22 only for legacy repair or where manual assembly and mechanical stability outweigh size constraints |
Compared with DBF210, MSB22ML offers measurable leakage and forward-loss reduction for efficiency-critical designs, while GAB22 trades miniaturization for mechanical robustness and broader availability in legacy distribution channels.

FAQ
Is DBF210 still in production?
No, DBF210 is officially obsolete and discontinued per Diodes Incorporated's datasheet revision 5-4 (February 2025). It is no longer manufactured, and Diodes recommends migrating to the pin-compatible successor MSB22ML for new designs.
What is the maximum operating temperature for DBF210?
The DBF210 has an operating junction temperature range of –55°C to +150°C. Its rated 2A average output current assumes TC = +110°C; derating curves show usable current drops to ~1.2A at TC = +125°C and ~0.6A at TC = +140°C.
Can DBF210 be used in automotive applications?
DBF210 is not AEC-Q200 qualified and lacks PPAP documentation or IATF 16949 manufacturing certification. Diodes explicitly states that automotive use requires contacting their representative for specially qualified alternatives-DBF210 is intended for commercial/industrial applications only.
What does the "-13" suffix in DBF210-13 indicate?
The "-13" denotes tape-and-reel packaging: 3,000 units per reel in DBF package format. This is the standard orderable part number for automated SMT placement; no electrical or thermal differences exist between DBF210-13 and other DBF210 variants.
