Product details
Overview
ES2JA_HF from Diodes Incorporated is a surface-mount super fast rectifier diode rated for 600 V repetitive peak reverse voltage, 2.0 A average forward current, and 50 A non-repetitive surge current, with 1.30 V forward voltage at 2 A and 25 ns reverse recovery time. It serves as a primary AC/DC input rectifier in compact offline switch-mode power supplies.
For engineers reviewing the ES2JA_HF datasheet, ES2JA_HF pinout, ES2JA_HF application, or ES2JA_HF equivalent, key selection criteria include reverse voltage margin for universal-input designs, thermal resistance (25 °C/W junction-to-lead), low leakage (<5 µA @ 25°C), halogen-free "Green" SMA package compliance, and fast switching performance in high-frequency flyback converters.
Technical Context
This device operates as a unidirectional silicon PN junction rectifier optimized for high-efficiency SMPS front-end stages. Its super-fast recovery (trr ≤ 25 ns) minimizes switching losses during turn-off, while the glass-passivated chip ensures stable reverse characteristics across temperature.
The SMA package enables direct PCB mounting with low thermal resistance (25 °C/W J–L), supporting reliable operation up to +150°C junction temperature. Reverse leakage remains below 200 µA at 125°C, critical for maintaining efficiency in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak line voltage surges in 230 VAC mains applications without breakdown |
| I(AV) | 2.0 A - Sustains continuous output current in 25–40 W adapter designs with proper heatsinking |
| VF @ 2A | 1.30 V - Limits conduction loss to ~2.6 W at full load, reducing thermal stress on PCB traces |
| trr | 25 ns - Enables operation up to ~500 kHz switching frequency with minimal reverse recovery loss |
| RthJL | 25 °C/W - Allows direct lead-to-PCB copper thermal path; 50°C rise at 2A requires ≥1 cm² 2-oz copper pad |
| IR @ 25°C | 5.0 µA - Ensures negligible standby power loss in energy-efficient no-load modes |
Pinout & Package
ES2JA_HF uses the SMA (DO-214AC) surface-mount package: molded green halogen-free plastic case, cathode indicated by band, weight ≈ 0.07 g, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for positive half-cycle conduction | Connected to AC line or transformer secondary; must withstand full VRRM during reverse bias |
| Cathode | Output terminal for rectified DC current | Feeds bulk capacitor or controller IC; polarity marking ensures correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip | Enhances long-term reliability under humidity and thermal cycling by preventing surface contamination-induced leakage |
| Super fast switching (trr ≤ 25 ns) | Reduces turn-off energy loss in high-frequency converters, improving overall efficiency by 0.5–1.2% vs. standard rectifiers |
| Low VF (1.30 V @ 2A) | Minimizes I²R conduction loss at full load, enabling smaller heatsinks or higher power density |
| Halogen- and antimony-free "Green" package | Meets RoHS 3 (2015/863/EU) and JEDEC JS709C requirements for eco-compliant industrial and consumer end equipment |
Applications
| AC/DC Adapter Input Rectification | USB PD Power Supply Front-End |
|---|---|
Use Scenario: 230 VAC input rectification in compact 30–45 W wall adapters with universal input range (90–264 VAC). IC Role / Device Role / Timing Role: Primary bridge or single-phase rectifier converting AC to pulsating DC before bulk capacitor and PWM controller. Use Value: 600 V VRRM provides 2× safety margin over peak 264 VAC (373 V), while 25 ns trr reduces EMI generation in high-frequency quasi-resonant topologies. | Use Scenario: Input rectification stage in 65 W USB Power Delivery chargers operating at 200–500 kHz switching frequencies. IC Role / Device Role / Timing Role: Fast-recovery rectifier in active clamp flyback or LLC resonant converter input stage. Use Value: Low IR (5 µA @ 25°C) prevents capacitor discharge during standby, meeting EU CoC Tier 2 no-load power < 75 mW requirements. |
| Industrial SMPS Auxiliary Supply | LED Driver Bulk Rectification |
Use Scenario: Auxiliary 12 V/200 mA bias supply in programmable logic controller (PLC) power modules with wide ambient (-40 to +70°C). IC Role / Device Role / Timing Role: Isolated auxiliary rectifier fed from small auxiliary winding on main transformer. Use Value: Stable IR < 200 µA at 125°C ensures consistent startup behavior and low quiescent loss across full industrial temperature range. | Use Scenario: Bulk rectification in outdoor-rated 100 W LED streetlight drivers exposed to high ambient temperatures (>60°C). IC Role / Device Role / Timing Role: Main input rectifier feeding high-voltage DC bus prior to buck or buck-boost regulation stage. Use Value: 150°C max junction temperature rating allows derated operation at elevated ambient without forced cooling, extending lifetime in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 600 V VRRM, but VF = 1.7 V @ 2A; trr = 35 ns; TO-220AC package | Requires through-hole mounting and external heatsink; higher conduction loss increases board-level thermal management complexity | Prefer when legacy through-hole layout exists and thermal budget permits higher VF |
| MBR260 | Schottky diode: VF = 0.65 V @ 2A, but VRRM only 60 V; no reverse recovery | Unsuitable for AC line rectification; limited to low-voltage DC–DC output stages | Select only for secondary-side synchronous rectification where reverse voltage < 48 V |
Compared with STTH2R06 and MBR260, ES2JA_HF uniquely balances high-voltage capability (600 V), low VF (1.30 V), ultrafast recovery (25 ns), and surface-mount compatibility-making it optimal for space-constrained, high-efficiency AC/DC front ends where thermal and EMI constraints are critical.

FAQ
What is the maximum allowable junction temperature for ES2JA_HF?
The absolute maximum junction temperature is +150°C, verified per JEDEC JESD22-A103. Operation at this limit requires strict thermal design: PCB copper area ≥1.5 cm² (2-oz), ambient ≤75°C, and no adjacent heat sources. Derating to 125°C junction improves long-term reliability in industrial applications.
Does ES2JA_HF meet automotive AEC-Q101 qualification?
No, ES2JA_HF is not AEC-Q101 qualified. It is rated for industrial and commercial applications only. For automotive front-end rectification, Diodes offers the AEC-Q101 qualified SB260 or SB360 series, which share the same SMA package but include extended temperature screening and failure analysis protocols.
Can ES2JA_HF replace a standard FR207 in an existing design?
Yes, ES2JA_HF can directly replace FR207 in most cases: both use SMA package and have identical pinout. However, ES2JA_HF's lower VF (1.30 V vs. 1.7 V) reduces conduction loss, and its faster trr (25 ns vs. 500 ns) lowers switching loss-but may increase EMI if snubber networks are not re-optimized for faster edge rates.
What is the meaning of "HF" in ES2JA_HF?
The "HF" suffix denotes Diodes Incorporated's standard halogen-free, lead-free, RoHS-compliant finish. It confirms compliance with EU Directive 2015/863/EU (RoHS 3), with bromine/chlorine <900 ppm each and antimony <1000 ppm, verified via material testing per IEC 62321-2.
