Product details

Overview

SR010 B0G from Taiwan Semiconductor is a 100 V, 0.5 A Schottky barrier rectifier in DO-204AL (DO-41) package, featuring VF = 0.85 V at IF = 0.5 A and IR = 100 µA at TJ = 25°C, used in high-efficiency DC/DC converters and automotive-grade power adapters.

For engineers reviewing the SR010 B0G datasheet, SR010 B0G pinout, SR010 B0G application, or SR010 B0G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), forward voltage drop (0.85 V), surge current rating (30 A), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification status.

Technical Context

This discrete Schottky diode uses a single-die construction with guard ring structure for overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its thermal resistance R_θJA is 50°C/W, enabling operation up to 150°C junction temperature under defined PCB layout conditions.

Electrical behavior is characterized by low capacitance (65 pF at 1 MHz, VR = 4.0 V), fast switching response, and stable reverse leakage (≤2 mA at TJ = 125°C), making it suitable for high-frequency switching topologies where conduction loss and recovery loss must be minimized.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse blocking voltage before breakdown
I_F	0.5 A - continuous average forward current at T_A = 25°C
I_FSM	30 A - non-repetitive surge current (8.3 ms half-sine) without damage
V_F	0.85 V - forward voltage drop at I_F = 0.5 A and T_J = 25°C, directly impacts conduction loss
I_R	100 µA - reverse leakage at rated V_R and T_J = 25°C, critical for standby power efficiency
T_J max	+150°C - maximum allowable junction temperature, supports extended thermal margin in sealed enclosures
C_J	65 pF - junction capacitance at 1 MHz and V_R = 4.0 V, limits high-frequency switching noise

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-1EQH01-M3/5BT	Same V_RRM (100 V), slightly higher V_F (0.92 V @ 0.5 A), TO-277 package (surface-mount)	Requires PCB redesign for SMD placement; better thermal performance on copper pads	Prefer when board space is constrained and thermal pad access is available

FAQ

What is the maximum junction temperature rating for SR010 B0G?

The SR010 B0G has a maximum junction temperature (T_J) of +150°C, verified per its absolute maximum ratings table. This allows reliable operation in high-ambient environments such as under-hood automotive applications or sealed industrial enclosures. Derating curves in the SR002–SR010 datasheet define safe I_F limits above 25°C ambient, and the SR010 B0G must be mounted on PCBs with adequate copper area to maintain T_J ≤ 150°C under full load.

Is SR010 B0G AEC-Q101 qualified?

Yes, SR010 B0G is AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code (SR010H variant) and explicit listing in the FEATURES section of the Taiwan Semiconductor SR002–SR010 datasheet (Version H2104). The "B0G" suffix denotes green compound and ammo box packaging, but qualification applies to the underlying die and assembly process used in SR010 B0G.

What is the forward voltage drop of SR010 B0G at rated current?

The SR010 B0G exhibits a typical forward voltage drop (V_F) of 0.85 V at I_F = 0.5 A and T_J = 25°C, per the ELECTRICAL SPECIFICATIONS table. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating. At elevated junction temperatures, V_F decreases slightly, improving conduction efficiency in thermally stabilized designs.

Does SR010 B0G have a guard ring structure?

Yes, SR010 B0G incorporates a guard ring structure, explicitly stated in the FEATURES section of the Taiwan Semiconductor SR002–SR010 datasheet. This design enhances edge termination robustness, improving resistance to surface flashover and transient overvoltage events-critical for reliability in noisy automotive and industrial power environments.

What is the reverse leakage current specification for SR010 B0G?

The SR010 B0G specifies a maximum reverse leakage current (I_R) of 100 µA at T_J = 25°C and rated V_R, and ≤2 mA at T_J = 125°C. These values are measured using a 30 ms pulse test (per Note 2), ensuring relevance to real-world transient conditions. Low I_R directly contributes to reduced standby power loss in always-on systems.
