Product details
Overview
SDM1U60P1-7 from Diodes Incorporated is a 1.0A, 60V surface-mount Schottky barrier rectifier in PowerDI123 package, featuring VF ≤ 0.50 V at 1.0A/25°C, IR ≤ 100 µA at 60V/25°C, and IFSM = 60A (8.3ms half-sine), used for reverse polarity protection in DC power inputs of industrial IoT sensors.
For engineers reviewing the SDM1U60P1-7 datasheet, SDM1U60P1-7 pinout, SDM1U60P1-7 application, or SDM1U60P1-7 equivalent, key selection criteria include low forward voltage for efficiency-critical 5V/3.3V rail protection, high surge rating for load-dump immunity, and PowerDI123 thermal performance (RθJA = 60°C/W on 1"² copper).
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche breakdown and patented interlocking clip design to sustain 60A non-repetitive surge current without bond wire failure. Its low 52pF junction capacitance at 10V enables stable operation in high-frequency switching environments.
Thermal resistance is specified as RθJC = 5°C/W (junction-to-case) and RθJA = 60°C/W (junction-to-ambient on 1"² 2oz copper), confirming suitability for compact PCB layouts with limited heatsinking. The device operates across –55°C to +150°C storage range and supports derated DC output up to 0.6A at +100°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets safe blocking margin for 48V DC systems. |
| IF(AV) | 1.0 A - Average forward current rating; defines continuous DC power path capacity at TA = 25°C. |
| VF Max | 0.50 V @ 1.0A, 25°C - Forward voltage drop; determines conduction loss (0.5W max at full load) and self-heating. |
| IR Max | 100 µA @ 60V, 25°C - Reverse leakage; ensures minimal standby power drain in battery-backed applications. |
| IFSM | 60 A @ 8.3ms - Non-repetitive surge rating; withstands automotive load-dump or hot-swap transients. |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance on standard 1"² copper pad; enables thermal design without external heatsink. |
| CT | 52 pF @ 10V, 1MHz - Junction capacitance; limits high-frequency noise coupling in fast-switching DC/DC feedback paths. |
Pinout & Package
Package: PowerDI123 - Surface-mount plastic package with matte tin-plated copper leadframe, UL 94V-0 rated, moisture sensitivity level 1, cathode band polarity indicator, weight 0.018 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to input supply rail; must route with low-inductance trace to minimize voltage overshoot during surge events. |
| Cathode | Forward current exit node / reverse-blocking terminal | Connected to protected load; cathode band marking identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche during voltage transients, improving reliability in unregulated input stages. |
| Patented interlocking clip design | Eliminates bond wire fatigue under repeated 60A surges, extending lifetime in cyclic load applications. |
| Low VF (0.40–0.50 V) | Reduces conduction loss by >30% vs. comparable silicon diodes, critical for thermally constrained sensor nodes. |
| RoHS-compliant & halogen-free | Meets IPC-1752A material declaration requirements for industrial and medical end equipment. |
Applications
| Industrial Sensor Power Protection | USB-C Port Reverse Polarity Guard |
|---|---|
Use Scenario: 24V DC-powered temperature/humidity sensor node with intermittent wireless transmission. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed between connector and LDO input. Use Value: 0.50V VF minimizes dropout across protection stage, preserving ≥22.5V input to downstream regulator under full 1A load. | Use Scenario: USB-C receptacle on portable test instrument accepting 5V/3A power delivery. IC Role / Device Role / Timing Role: Blocking diode preventing damage from miswired upstream power source. Use Value: 100µA IR at 25°C ensures <0.5mW standby loss; 60A IFSM handles accidental short-to-rail events. |
| LED Driver Input Stage | Programmable Logic Controller (PLC) Input Module |
Use Scenario: Constant-current LED driver board powered from 12V DC bus with PWM dimming. IC Role / Device Role / Timing Role: Input rectifier and reverse protection element before bulk capacitor. Use Value: 52pF CT avoids high-frequency resonance with 100µF electrolytic capacitor, stabilizing input ripple. | Use Scenario: 24V digital input module detecting dry-contact closure in factory automation. IC Role / Device Role / Timing Role: Reverse voltage clamp on field-side signal line. Use Value: Guard ring structure prevents latch-up during ESD events per IEC 61000-4-2 Level 4 (±15kV air). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16-E3/5AT (Vishay) | Same 60V VRRM, 1A IF(AV), but VF = 0.75V @ 1A - 50% higher conduction loss. | Higher thermal rise limits use in sealed enclosures above 60°C ambient. | Select only if legacy footprint compatibility with SMA package is required. |
| SB160-TB (ON Semiconductor) | Identical PowerDI123 package, but IR = 500µA @ 60V - 5× higher leakage than SDM1U60P1-7. | Unsuitable for battery-operated devices requiring <1µA sleep current. | Prefer for cost-sensitive non-battery applications where leakage is not critical. |
Compared with SS16-E3/5AT and SB160-TB, SDM1U60P1-7 delivers the lowest VF (0.50V) and lowest IR (100µA) in PowerDI123, making it optimal for thermally constrained, low-quiescent-power industrial sensing nodes.

FAQ
What is the maximum operating temperature for SDM1U60P1-7?
The SDM1U60P1-7 has a storage temperature range of –55°C to +150°C and a maximum junction temperature of +150°C. Its DC forward current derates linearly to 0.6A at +100°C ambient when mounted on a 1"² copper pad, per Figure 4 in DS39462 Rev. 2–2.
Is SDM1U60P1-7 suitable for automotive applications?
SDM1U60P1-7 is not AEC-Q200 qualified and lacks automotive-specific qualification testing. While its 60A surge rating and –55°C to +150°C range meet some automotive environmental demands, Diodes Incorporated does not authorize its use in safety-critical vehicle subsystems without additional system-level validation.
Does SDM1U60P1-7 require a heatsink in typical applications?
No heatsink is required for SDM1U60P1-7 in standard applications. With RθJA = 60°C/W on a 1"² 2oz copper pad, junction temperature rise is ~30°C at 1.0A/25°C ambient (0.50V × 1.0A × 60°C/W), well within the 150°C limit. Layout optimization suffices.
How is polarity identified on the SDM1U60P1-7 package?
Polarity is marked by a visible cathode band on the top surface of the PowerDI123 package. Per the datasheet top view diagram, the banded end corresponds to the cathode terminal; the opposite end is the anode. This matches standard PCB silkscreen conventions for Schottky rectifiers.
