Product details

Overview

SD101BWS-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in SOD-323 package, rated for 50 V peak repetitive reverse voltage, 15 mA forward current, and 0.40 V forward voltage at 1.0 mA - optimized for low-power signal rectification and ESD-sensitive signal path protection in portable electronics.

For engineers reviewing the SD101BWS-7 datasheet, SD101BWS-7 pinout, SD101BWS-7 application, or SD101BWS-7 equivalent, key selection criteria include its 2.1 pF junction capacitance, 1.0 ns reverse recovery time, negligible stored charge, ultra-low leakage (200 nA @ 40 V), and guard-ring protected construction for transient robustness.

Technical Context

This Schottky diode uses a planar epitaxial structure with guard ring passivation to suppress edge breakdown and improve surge tolerance. Its metal-semiconductor junction delivers near-zero reverse recovery charge and eliminates minority-carrier storage delay.

Designed for high-frequency signal routing, it operates across –65 °C to +125 °C with thermal resistance of 625 °C/W on FR-4 PCBs using recommended pad layout. The SOD-323 package supports automated placement and reflow compatibility per J-STD-020A Level 1 moisture sensitivity.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - maximum non-repetitive reverse blocking capability before avalanche onset
V_F @ 1.0 mA	0.40 V - enables efficient signal-level clamping with minimal forward drop penalty
I_R @ 40 V	200 nA - ensures negligible leakage in battery-backed or high-impedance sensing nodes
C_T @ 0 V	2.1 pF - preserves signal integrity in RF/IF paths up to ~1 GHz
t_rr	1.0 ns - supports >300 MHz switching without tail current or ringing
P_D	200 mW - defines absolute power limit under derated ambient conditions
R_JA	625 °C/W - determines junction temperature rise above ambient on standard FR-4 layout

Pinout & Package

SOD-323 plastic surface-mount package (UL 94V-0 rated), dimensions: 2.30–2.70 mm (L) × 1.60–1.80 mm (W) × 1.20–1.40 mm (H); cathode indicated by band; polarity confirmed per Diodes Inc. mechanical drawing DS30078 Rev. 5.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node in clamping or rectification path
Cathode	Forward current exit / reverse blocking terminal	Banded end; ties to higher-potential rail or signal return for ESD shunting

Key Features

Feature	Design Value
Guard ring construction	Prevents premature edge breakdown under transient stress, improving reliability in I/O protection
Negligible reverse recovery time	Eliminates switching losses and oscillation in high-speed signal routing
Low forward voltage (0.40 V @ 1 mA)	Reduces forward conduction loss in low-current bias and detection circuits
Ultra-small SOD-323 footprint	Enables dense layout in space-constrained wearables and IoT sensor nodes
Moisture sensitivity Level 1	Allows unlimited floor life without dry pack or baking prior to assembly

Applications

USB Data Line Protection

RF Signal Path Clamping

Use Scenario: Protecting USB 2.0 D+/D− lines from ESD events per IEC 61000-4-2 Level 4.

IC Role / Device Role / Timing Role: Bidirectional low-capacitance clamp between data line and ground.

Use Value: 2.1 pF capacitance avoids signal integrity degradation; 1.0 ns t_rr prevents data pulse distortion during fast transients.

Use Scenario: Preventing receiver front-end damage from antenna-coupled RF surges in sub-GHz ISM band receivers.

IC Role / Device Role / Timing Role: Low-leakage DC blocking and transient shunt at LNA input.

Use Value: 200 nA reverse leakage preserves bias stability; guard ring withstands 8 kV contact discharge without parametric shift.

Low-Power Sensor Biasing

Portable Audio Signal Routing

Use Scenario: Providing precision bias current to MEMS microphone or thermistor interface with minimal voltage error.

IC Role / Device Role / Timing Role: Forward-biased current source element in analog front-end.

Use Value: 0.40 V V_F at 1 mA reduces headroom demand by >60 mV versus standard silicon diodes.

Use Scenario: Isolating DAC output from headphone amplifier input while enabling DC coupling.

IC Role / Device Role / Timing Role: Low-capacitance series blocking diode in audio signal path.

Use Value: 2.1 pF C_T avoids high-frequency roll-off below 20 kHz; SOD-323 fits tight pitch between codec and amp ICs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SD101AWS-7	60 V V_RRM, 0.41 V V_F @ 1 mA, 2.0 pF C_T	Higher reverse voltage margin; slightly higher forward drop	Select when system requires >50 V blocking but can accept +0.01 V V_F penalty
SD101CWS-7	40 V V_RRM, 0.39 V V_F @ 1 mA, 2.2 pF C_T	Lower V_RRM but lowest forward voltage; marginally higher capacitance	Choose for ultra-low-voltage signal paths where reverse stress stays <40 V

Compared with SD101AWS-7 and SD101CWS-7, SD101BWS-7 balances reverse voltage headroom (50 V), forward efficiency (0.40 V), and capacitance (2.1 pF), making it optimal for general-purpose 3.3 V/5 V interface protection where all three parameters must be simultaneously constrained.

FAQ

Is SD101BWS-7 RoHS compliant and lead-free?

Yes, SD101BWS-7 is RoHS compliant and features matte tin lead finish. It meets JEDEC J-STD-020A Level 1 moisture sensitivity requirements and is compatible with standard Pb-free reflow profiles. No special handling or baking is required prior to assembly.

What is the maximum continuous forward current rating?

The SD101BWS-7 is rated for 15 mA continuous forward current at 25 °C ambient with specified PCB pad layout. Derating applies above 25 °C per the power dissipation curve: at 85 °C ambient, max I_F drops to approximately 9.5 mA to maintain P_D ≤ 200 mW.

Can SD101BWS-7 be used in place of a 1N5711?

No - the 1N5711 is a through-hole axial diode with 70 V V_RRM, 150 mA I_F, and TO-226 package. SD101BWS-7 is an SOD-323 Schottky with 50 V V_RRM, 15 mA I_F, and fundamentally different thermal and layout constraints. Direct substitution is not electrically or mechanically viable.

Does SD101BWS-7 have SPICE model support?

Yes, Diodes Incorporated provides verified SPICE models for SD101BWS-7, including nonlinear capacitance and dynamic resistance behavior. These models are published in the DS30078 datasheet Rev. 5 and downloadable from the manufacturer's website under "Simulation Models" for SD101xWS series.
