Product details
Overview
SR009HR0G from Taiwan Semiconductor is a 0.5A, 90V repetitive peak reverse voltage Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.85V max forward voltage at 0.5A and 100µA max reverse leakage at 25°C, used in compact DC-DC converters and automotive-grade power adapters.
For engineers reviewing the SR009HR0G datasheet, SR009HR0G pinout, SR009HR0G application, or SR009HR0G equivalent, key selection criteria include its AEC-Q101 qualification, 30A surge rating, 65pF junction capacitance, -55°C to +150°C operating junction temperature, and RoHS/halogen-free compliance for high-reliability embedded power designs.
Technical Context
This Schottky rectifier employs a single-die construction with guard ring overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its thermal resistance is 50°C/W junction-to-ambient, enabling stable operation up to 150°C junction temperature under defined derating conditions.
Electrical behavior is characterized by low conduction loss (VF ≤ 0.85V @ IF = 0.5A), tight reverse leakage control (IR ≤ 100µA @ VR = 90V, TJ = 25°C; ≤2mA @ TJ = 125°C), and 65pF junction capacitance at 1MHz/4V - optimized for high-frequency switching efficiency in SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse blocking voltage; defines safe DC/peak AC input range in flyback or buck converters |
| IF | 0.5 A - continuous forward current rating; sets output power limit in low-power adapter designs |
| VF (max) | 0.85 V @ 0.5A, 25°C - directly determines conduction loss and thermal rise in high-duty-cycle operation |
| IR (max) | 100 µA @ 90V, 25°C - ensures minimal standby power loss in energy-sensitive applications |
| CJ | 65 pF @ 1MHz, 4V - impacts high-frequency switching noise and EMI filter sizing |
| IFSM | 30 A @ 8.3ms half-sine - supports robust inrush current handling during cold-start events |
| TJ max | +150°C - enables use in under-hood automotive environments without forced cooling |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case meeting UL 94V-0; polarity indicated by cathode band; weight ≈0.330g.

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-2EJH09-M3/5AT | Same 90V VRRM, 0.5A IF, but VF = 0.72V typ (vs. 0.85V max for SR009HR0G); TO-277 package | Surface-mount alternative for automated assembly; lacks AEC-Q101 qualification | Preferred when SMT layout and lower VF outweigh automotive qualification needs |
| ON Semiconductor SB05K90 | 90V VRRM, 0.5A IF, VF = 0.82V max, AEC-Q101 qualified, same DO-41 package | Direct form-fit replacement with tighter VF spec and identical qualification level | Best drop-in alternative when tighter forward voltage tolerance is required |
Compared with VS-2EJH09-M3/5AT, SR009HR0G offers automotive qualification and through-hole assembly compatibility; versus SB05K90, it trades slightly higher VF tolerance for cost-effective sourcing and identical mechanical integration - both alternatives require validation of thermal interface and surge margin in final layout.

FAQ
What is the maximum junction temperature rating for SR009HR0G?
The SR009HR0G has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings when derated per the forward current derating curve in the datasheet. Thermal design must account for its 50°C/W junction-to-ambient resistance under natural convection.
Is SR009HR0G pin-compatible with other parts in the SR002–SR010 family?
Yes, all SR002–SR010 devices share identical DO-204AL (DO-41) packaging and axial lead configuration, making SR009HR0G mechanically interchangeable with SR002HR0G through SR010HR0G. However, electrical parameters differ - notably VRRM (90V), VF (0.85V max), and IR (100µA max) - so substitution requires verification against circuit voltage and loss requirements.
Does SR009HR0G meet automotive qualification standards?
Yes, the "H" suffix in SR009HR0G explicitly denotes AEC-Q101 qualification, confirmed in the manufacturer's ordering information and features list. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - essential for automotive body control, lighting, and infotainment power supplies.
What is the reverse leakage current specification for SR009HR0G at elevated temperature?
At TJ = 125°C and rated VR = 90V, SR009HR0G specifies a maximum reverse leakage current (IR) of 2mA, per the electrical specifications table. This value is critical for standby power budgeting in always-on systems; at 25°C, IR is limited to 100µA, offering tighter control during normal operation.
What packaging options are available for SR009HR0G?
SR009HR0G is supplied in two standard configurations: 5,000 units per tape-and-reel (ordering code SR009HR0G) and 3,000 units per ammo box (ordering code SR009HRA0G). Both use DO-204AL (DO-41) packaging with green molding compound and cathode-band polarity marking, fully compliant with RoHS and halogen-free requirements.
