Product details
Overview
SD101AWS-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in SOD323 package, rated for 60 V peak repetitive reverse voltage, 15 mA forward current, and 0.41 V max forward voltage at 1.0 mA. It features negligible reverse recovery time (1.0 ns), low capacitance (2.0 pF), and guard ring construction for transient protection-used in high-speed signal clamping and low-power rail-to-rail protection circuits.
For engineers reviewing the SD101AWS-7 datasheet, SD101AWS-7 pinout, SD101AWS-7 application, or SD101AWS-7 equivalent, key selection criteria include its 60 V VRRM, ultra-low 1.0 ns tRR, 2.0 pF CT at 0 V, cathode-band polarity marking, and SOD323 footprint compatibility with space-constrained portable and automotive signal-path designs.
Technical Context
This Schottky diode leverages platinum-silicide or similar low-barrier metallization to achieve sub-0.45 V forward drop and near-zero minority-carrier storage, enabling operation up to ~500 MHz in RF detector and sampling applications. Its guard ring structure provides enhanced ESD robustness without compromising junction capacitance.
The SOD323 package delivers thermal resistance of 625 °C/W (junction-to-ambient) on FR-4 with recommended pad layout, supporting continuous operation from –65 °C to +125 °C. Reverse leakage remains ≤200 nA at 50 V, critical for precision bias and hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - supports 48 V system-level transient suppression without breakdown |
| VF (max) | 0.41 V @ 1.0 mA - minimizes forward conduction loss in low-voltage logic interface protection |
| tRR | 1.0 ns - enables use in >300 MHz signal routing and RF envelope detection |
| CT | 2.0 pF @ 0 V, 1 MHz - preserves signal integrity in high-speed data line clamping |
| IF (cont) | 15 mA - suitable for low-current biasing, level shifting, and sensing paths |
| PD | 200 mW - limits self-heating in compact PCB layouts with minimal copper area |
Pinout & Package
SOD323 is a 2-terminal ultra-small plastic surface-mount package (2.7 mm × 1.3 mm × 0.9 mm), with cathode identified by a band on the top surface. Terminals are matte tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to higher-potential node during conduction; requires trace routing clearance for thermal relief |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Must be tied to reference or lower-potential rail; band orientation defines PCB placement polarity |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring construction | Improves ESD tolerance and prevents edge breakdown under fast transients (IEC 61000-4-2 Level 3 compatible) |
| Negligible reverse recovery time | Eliminates switching tail current, reducing cross-conduction risk in bidirectional signal paths |
| Low forward voltage drop | Enables efficient clamping in 1.8–3.3 V logic domains without forward bias saturation |
| Ultra-small SOD323 footprint | Reduces board area by >50% vs. SOD123, critical for wearables and miniaturized sensor modules |
Applications
| USB Data Line Protection | Automotive CAN Bus Biasing |
|---|---|
Use Scenario: Clamping ESD transients on USB 2.0 D+/D− lines before entering PHY ICs. IC Role / Device Role / Timing Role: Passive bidirectional voltage clamp protecting high-impedance differential receivers. Use Value: 2.0 pF capacitance avoids signal rise-time degradation; 1.0 ns tRR ensures no pulse distortion during 480 Mbps data bursts. | Use Scenario: Providing common-mode bias and transient suppression on CAN H/L lines in body control modules. IC Role / Device Role / Timing Role: Low-leakage DC bias path with fast transient shunting capability. Use Value: ≤200 nA IR at 50 V maintains bus idle voltage stability; 60 V VRRM withstands load-dump spikes per ISO 7637-2. |
| RF Detector Input Stage | Low-Power Sensor Signal Conditioning |
Use Scenario: Rectifying RF envelope signals in 868/915 MHz ISM-band receiver front-ends. IC Role / Device Role / Timing Role: Zero-bias Schottky detector diode operating without external bias supply. Use Value: Sub-0.41 V VF enables sensitivity down to –20 dBm; low CT preserves RF impedance match. | Use Scenario: Level-shifting and overvoltage protection for analog outputs of MEMS pressure sensors. IC Role / Device Role / Timing Role: Signal-path isolation diode preventing backfeed into low-current sensor output stages. Use Value: 15 mA IF rating safely handles sensor fault currents; 0.41 V VF introduces <1 mV error in 10-bit ADC reference paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | 40 V VRRM, 0.32 V VF @ 10 mA, SOT-23 package (larger footprint) | Better VF at higher current, but insufficient for 48 V systems | Select when forward efficiency > reverse voltage rating in 3.3 V–5 V logic rails |
| BAT54CW | 30 V VRRM, 0.24 V VF @ 10 mA, SOD323 package, dual configuration | Lower voltage rating; dual-diode layout adds routing complexity | Choose only if dual-channel clamping is required and system VRMS < 21 V |
Compared with SBAT54LT1G and BAT54CW, SD101AWS-7 uniquely balances 60 V standoff, ultra-low capacitance, and SOD323 size-making it optimal for space-limited, high-voltage transient protection where leakage and speed are critical.

FAQ
Is SD101AWS-7 qualified for automotive applications?
No-SD101AWS-7 is not AEC-Q101 qualified. While it operates from –65 °C to +125 °C and uses IATF 16949-manufactured processes, Diodes explicitly states that automotive-grade variants require PPAP-capable change control and separate qualification. For automotive use, contact Diodes for AEC-Q101-compliant equivalents such as the B130LAW-7.
What is the maximum reverse voltage SD101AWS-7 can sustain continuously?
The SD101AWS-7 has a peak repetitive reverse voltage (VRRM) of 60 V and a working peak reverse voltage (VRWM) of 60 V. Continuous DC blocking voltage (VR) is also rated at 60 V. Derating is not required below +125 °C ambient, but power dissipation must remain ≤200 mW per the thermal curve in Figure 4.
Does SD101AWS-7 have a specified ESD rating?
The datasheet does not specify an IEC 61000-4-2 or HBM ESD rating. However, its guard ring construction improves transient immunity, and typical performance meets ±8 kV contact discharge in system-level testing when properly laid out. For guaranteed ESD protection, Diodes recommends pairing it with dedicated TVS devices like the D24Z3.
Can SD101AWS-7 replace BAT54 series diodes in existing designs?
Yes-if the design requires ≥60 V reverse standoff and fits the SOD323 footprint. SD101AWS-7 offers higher VRRM than BAT54x (30 V) and lower capacitance than most BAT54 variants (2.0 pF vs. 10–15 pF), but its forward voltage is slightly higher at low current. Verify layout clearance and thermal margin, as PD remains 200 mW.
