Product details
Overview
SR520HB0G from Taiwan Semiconductor is a 5 A, 200 V AEC-Q101-qualified Schottky barrier rectifier in DO-201AD package, featuring 1.05 V max forward voltage at 5 A and 100 µA max reverse leakage at 25°C, used in high-efficiency DC/DC converters and automotive-grade power supplies.
For engineers reviewing the SR520HB0G datasheet, SR520HB0G pinout, SR520HB0G application, or SR520HB0G equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 120 A surge current rating, 150°C maximum junction temperature, RoHS and halogen-free compliance, and AEC-Q101 qualification for automotive reliability.
Technical Context
This single-die Schottky rectifier uses a guard ring structure to enhance overvoltage robustness and supports high dv/dt (10,000 V/µs), enabling stable operation in fast-switching topologies. Its low VF and low IR values are specified at both 25°C and 125°C, supporting thermal-aware design in compact power stages.
The device operates with a junction-to-case thermal resistance of 6°C/W and junction-to-ambient of 35°C/W, allowing direct heatsink mounting or PCB copper area optimization. It is rated for continuous forward current up to 5 A with derating above 25°C ambient per the published derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or buck-boost output rectification |
| IF | 5 A - Continuous average forward current; sets minimum trace width and thermal pad requirements on PCB |
| VF (max) | 1.05 V @ 5 A, 25°C - Directly determines conduction loss (5.25 W max at full load) and thermal rise |
| IR (max) | 100 µA @ 200 V, 25°C - Low leakage enables stable hold-up in standby and light-load conditions |
| IFSM | 120 A - Peak non-repetitive surge current handling; supports inrush and transient overload without failure |
| TJ (max) | 150°C - Enables operation in under-hood automotive environments without derating below 125°C ambient |
| RθJC | 6°C/W - Confirms effective thermal path to heatsink; allows accurate junction temperature estimation during layout |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in synchronous buck); requires low-inductance routing |
| Cathode | Forward current exit / reverse voltage reference | Connected to output rail; polarity marked by visible band; must be routed away from sensitive analog traces |

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-5EWH02-M3/45 | 200 V, 5 A, VF = 0.87 V max @ 5 A, 25°C; TO-277 package (surface-mount) | Requires SMT reflow and different footprint; lacks AEC-Q101 qualification | Preferred where board space is constrained and automotive qualification is not required |
| ON Semiconductor SB5200-E3/54 | 200 V, 5 A, VF = 1.15 V max @ 5 A, 25°C; DO-201AD package, no AEC-Q101 | Same axial package but higher VF increases conduction loss by ~95 mW at 5 A | Acceptable for cost-sensitive industrial designs where 150°C TJ and automotive qualification are not mandatory |
Compared with VS-5EWH02-M3/45 and SB5200-E3/54, SR520HB0G uniquely combines AEC-Q101 qualification, 1.05 V VF, and DO-201AD through-hole compatibility-making it optimal for automotive and legacy industrial upgrades requiring drop-in reliability without layout change.

FAQ
What does the "H" suffix in SR520HB0G indicate?
The "H" in SR520HB0G denotes AEC-Q101 qualification, confirming that the SR520HB0G has undergone rigorous stress testing-including temperature cycling, humidity bias, and high-temperature operating life-for use in automotive electronic systems. This qualification is verified per the full AEC-Q101 test plan and documented in TSC's certification reports.
Is SR520HB0G compatible with lead-free reflow soldering?
Yes, SR520HB0G features pure tin-plated leads compliant with J-STD-002 and rated for lead-free reflow profiles. The DO-201AD package withstands peak temperatures up to 260°C for 10 seconds, matching IPC/JEDEC J-STD-020 requirements for SnPb-free assembly.
What is the maximum allowable junction temperature for SR520HB0G?
The SR520HB0G has a maximum junction temperature (TJ) of +150°C, validated across its full operating range. This rating is confirmed in the Absolute Maximum Ratings table and supported by thermal performance data (RθJC = 6°C/W), enabling use in under-hood automotive and high-ambient industrial applications.
How does SR520HB0G differ from non-AEC-Q101 versions like SR520B0G?
SR520HB0G includes full AEC-Q101 qualification, extended temperature screening, and enhanced process controls versus SR520B0G. Electrically identical in VRRM, IF, and VF, the "H" version adds automotive-grade reliability documentation, lot traceability, and failure rate reporting per AEC standards.
Can SR520HB0G replace SR515HB0G in an existing design?
Yes, SR520HB0G is a direct upgrade from SR515HB0G-same DO-201AD package, pinout, and thermal profile-with higher VRRM (200 V vs. 150 V) and identical 5 A IF rating. No PCB changes are needed, and the higher voltage margin improves safety margin in 48 V and 60 V systems.
