Product details
Overview
SR002HR0G from Taiwan Semiconductor is a 0.5A, 20V AEC-Q101-qualified Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.55V max forward voltage at 0.5A/25°C, 30A surge capability, and 50°C/W junction-to-ambient thermal resistance for high-efficiency DC/DC conversion in automotive power supplies.
For engineers reviewing the SR002HR0G datasheet, SR002HR0G pinout, SR002HR0G application, or SR002HR0G equivalent, key selection factors include its AEC-Q101 qualification, low VF under rated current, guard ring–enabled overvoltage protection, and DO-41 mechanical compatibility with legacy through-hole SMPS layouts.
Technical Context
This discrete Schottky diode operates as a unidirectional power rectifier with single-die construction and cathode-band polarity marking. Its 20V repetitive peak reverse voltage (VRRM) and 30A non-repetitive surge rating (IFSM) support transient-heavy input stages in compact adapters and onboard DC/DC converters.
Thermal performance is defined by RθJA = 50°C/W and maximum junction temperature of 125°C (derated above 25°C ambient), while the pure tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum continuous reverse blocking voltage before breakdown |
| IF | 0.5 A - Continuous average forward current at TA = 25°C |
| VF (max) | 0.55 V @ 0.5A, 25°C - Directly determines conduction loss and thermal rise in high-frequency switching paths |
| IFSM | 30 A - Peak non-repetitive surge current tolerance for line transients and startup inrush |
| RθJA | 50 °C/W - Enables thermal design without forced airflow in space-constrained adapter PCBs |
| Junction Temp | −55°C to +125°C - Specifies operating envelope for under-hood automotive modules |
| CJ | 110 pF @ 1 MHz, 4 V - Limits high-frequency switching noise and EMI in >100 kHz converters |
Pinout & Package
DO-204AL (DO-41) axial-leaded package with cathode indicated by a colored band; no active pins-two terminals only: anode (unmarked end) and cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side; must withstand full surge current and thermal cycling |
| Cathode | Forward current exit point | Marked with band; ties to output/load ground or return path; guards against reverse polarity misconnection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test plan |
| Guard ring structure | Prevents premature edge breakdown under high dv/dt or localized overvoltage stress |
| Low VF (0.55 V max) | Reduces conduction loss by >30% vs. comparable silicon rectifiers at 0.5A, improving efficiency in 5–12 V outputs |
| UL 94V-0 molding compound | Ensures flame retardancy in enclosed power adapter housings without additional potting |
| Pure tin plating | Enables lead-free reflow and wave soldering without intermetallic degradation or dewetting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EJH02-M3/54 | Same DO-41 package, 20 V VRRM, but 0.45 V typical VF at 0.5A and −65°C to +150°C TJ | Higher max junction temperature supports extended industrial operation beyond 125°C ambient | Preferred when operating near thermal limits or requiring wider storage temp range |
| ON Semiconductor SB0520 | DO-41, 20 V, 0.5 A, but not AEC-Q101 qualified and 0.6 V max VF at 0.5A | Lacks automotive qualification and has higher conduction loss | Suitable for cost-driven consumer adapters where AEC-Q101 is not mandated |
Compared with VS-2EJH02-M3/54 and SB0520, SR002HR0G uniquely combines AEC-Q101 compliance, 0.55 V max VF, and DO-41 manufacturability-making it optimal for automotive-qualified, thermally constrained, and high-volume through-hole power designs.

FAQ
What is the maximum junction temperature rating for SR002HR0G?
The SR002HR0G has a maximum junction temperature (TJ) of +125°C under normal operating conditions. This rating is validated per AEC-Q101 stress testing and defines the upper thermal limit for reliable long-term operation in automotive and industrial environments. Exceeding this temperature risks accelerated parametric drift and reduced lifetime. Derating curves in the SR002HR0G datasheet specify allowable forward current reduction above 25°C ambient.
Is SR002HR0G pin-compatible with standard DO-41 rectifiers?
Yes, SR002HR0G uses the industry-standard DO-204AL (DO-41) axial package with identical mechanical dimensions and lead spacing as generic DO-41 rectifiers. Its anode and cathode terminals align with conventional DO-41 orientation-cathode marked by a band-and supports direct replacement in existing through-hole layouts without PCB modification.
Does SR002HR0G meet RoHS and halogen-free requirements?
Yes, SR002HR0G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and all terminations use pure tin plating-ensuring full compliance with EU RoHS Directive 2011/65/EU and JEDEC JS709C material declarations for green electronics manufacturing.
What is the reverse leakage current specification for SR002HR0G at 100°C?
At TJ = 100°C and rated reverse voltage (20 V), the SR002HR0G exhibits a maximum reverse leakage current (IR) of 10 mA. This value is measured under pulsed conditions (PW = 30 ms) and reflects real-world thermal stress in high-ambient applications such as under-dash automotive modules or enclosed industrial enclosures.
How does the guard ring in SR002HR0G improve reliability?
The guard ring in SR002HR0G is a diffusion-based structural feature that suppresses edge electric field crowding, preventing premature avalanche breakdown at the die periphery. This enhances robustness against voltage transients, dv/dt-induced failure, and localized overvoltage events-critical for automotive load dump immunity and industrial surge survivability in the SR002HR0G's target applications.
