Product details
Overview
SDM1U30CP3-7 from Diodes Incorporated is a 30 V, 1 A Schottky barrier rectifier in X3-DSN1006-2 surface-mount package, featuring VF = 500 mV max at 1 A and IR = 150 µA max at 20 V, optimized for low-loss DC/DC conversion in space-constrained portable power rails.
For engineers reviewing the SDM1U30CP3-7 datasheet, SDM1U30CP3-7 pinout, SDM1U30CP3-7 application, or SDM1U30CP3-7 equivalent, key selection criteria include forward voltage drop at rated current, reverse leakage at operating bias, thermal resistance (RθJA = 70 °C/W on 1-in² copper), and ultra-thin 0.275 mm profile for stacked PCB designs.
Technical Context
This Schottky rectifier uses a planar die structure with NiAu bump terminals to achieve low RθJA (70 °C/W) on standard FR-4 with 1 in² copper pour, enabling high-current operation without external heatsinking. Its junction capacitance (CT = 29 pF at VR = 10 V) supports high-frequency switching up to 1 MHz.
The device operates across –55 °C to +150 °C and sustains IFSM = 10 A non-repetitive surge, making it suitable for transient-heavy input stages in buck-boost and flyback topologies where fast recovery and minimal stored charge are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking capability before breakdown, sufficient for 24 V nominal bus protection |
| IO | 1 A - Continuous DC output current rating under defined thermal conditions (70 °C/W RθJA) |
| VF Max | 500 mV @ 1 A - Limits conduction loss to ≤500 mW, directly improving efficiency in 1 A power paths |
| IR Max | 150 µA @ 20 V - Low leakage preserves battery runtime in always-on reverse-protection circuits |
| RθJA | 70 °C/W - Achieved on 1 in² 2 oz copper; enables 1 A operation at +85 °C ambient without derating |
| CT | 29 pF @ 10 V - Minimizes capacitive switching loss and EMI in >500 kHz DC/DC converters |
| IFRM | 4 A - Peak pulsed forward current (1 ms, 25% duty), supports short-duration load transients |
Pinout & Package
Package: X3-DSN1006-2 - ultra-compact 1.0 × 0.6 mm, 0.275 mm height, NiAu bump terminals, cathode dot marked.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Blocking Diode | Boost Diode |
|---|---|
Use Scenario: Prevents backfeed from a Li-ion battery into USB VBUS during charging circuit failure. IC Role / Device Role: Unidirectional current gate in power-path management. Use Value: 150 µA leakage at 20 V minimizes standby drain; 500 mV VF avoids voltage sag under 1 A load. | Use Scenario: Output rectifier in 1 A, 500 kHz boost converter powering a PMOLED display. IC Role / Device Role: High-efficiency synchronous rectification replacement. Use Value: 29 pF CT and fast Schottky recovery reduce switching loss and output ripple vs PN diodes. |

Use Scenario: Input polarity guard for a wearable sensor node powered by replaceable coin cell. IC Role / Device Role: Fail-safe reverse-voltage clamp on main power rail. Use Value: 30 V VRRM withstands accidental 24 V adapter misconnection; 0.275 mm height fits thin enclosures. | Use Scenario: Freewheeling path in a 1 A, 1 MHz buck regulator driving an optical module. IC Role / Device Role: Fast-recovery path for inductor current during high-side switch off-time. Use Value: 10 A IFSM handles peak inductor current surges; low CT prevents ringing-induced EMI. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TE25 | Higher VF (600 mV @ 1 A), larger SOD-323 package (1.7 × 1.3 mm) | Less suitable for ultra-thin or high-density layouts due to 0.9 mm height and 2.2 mm² area | Choose if legacy footprint compatibility outweighs efficiency and space savings |
| SS12 | Same VF spec (500 mV), but DO-214AC package (4.3 × 2.6 mm, 2.2 mm height) | Requires 7× more board area; thermal resistance >100 °C/W limits 1 A use without heatsink | Prefer only for through-hole prototyping or low-frequency, low-density designs |
Compared with RB050M-30TE25 and SS12, SDM1U30CP3-7 delivers superior power density (0.6 mm²), lower thermal resistance (70 °C/W), and thinner profile-critical for modern portable electronics where board space and thermal headroom are constrained.

FAQ
What is the maximum continuous operating temperature for SDM1U30CP3-7?
The SDM1U30CP3-7 has a specified operating junction temperature range of –55 °C to +150 °C. When mounted on a 1 in² 2 oz copper pad (RθJA = 70 °C/W), it supports 1 A continuous current up to +85 °C ambient without derating. At higher ambient temperatures, current must be reduced per Figure 4 derating curve.
Is SDM1U30CP3-7 compatible with lead-free reflow processes?
Yes. SDM1U30CP3-7 features NiAu bump terminals qualified per MIL-STD-202, Method 208, and is fully RoHS 3 compliant (2015/863/EU). It supports standard lead-free reflow profiles with peak temperatures up to 260 °C, and its moisture sensitivity level is rated J-STD-020 Level 1.
How does the X3-DSN1006-2 package differ from standard DFN1006?
The X3-DSN1006-2 package measures 1.0 × 0.6 mm with 0.275 mm height-30% thinner than typical DFN1006 variants-and uses NiAu bumps instead of solderable metallization. Its thermal performance (RθJA = 70 °C/W) exceeds standard DFN1006 (typically >120 °C/W), due to optimized copper pad coupling and low-profile thermal path.
Can SDM1U30CP3-7 be used in automotive body electronics?
SDM1U30CP3-7 meets AEC-Q200 stress test requirements for passive components but is not AEC-Q101 qualified as a discrete semiconductor. It is suitable for non-safety-critical automotive body electronics (e.g., interior lighting, sensors) where ambient temperature stays within –40 °C to +105 °C and design margins accommodate its 150 °C max junction rating.
