Product details
Overview
APD160VD-E1 from Diodes Incorporated is a dual Schottky barrier rectifier in DO-41 package, rated for 60 V repetitive peak reverse voltage, 1 A average forward current, and 0.68 V max forward voltage at 1 A and +25°C. It delivers low conduction loss and high surge capability (35 A peak) for medium-voltage, high-frequency power conversion circuits.
For engineers reviewing the APD160VD-E1 datasheet, APD160VD-E1 pinout, APD160VD-E1 application, or APD160VD-E1 equivalent, key selection criteria include forward voltage drop at operating current, thermal resistance (80 °C/W), junction temperature range (–65 to +125 °C), and RoHS-compliant green packaging with matte tin annealed leads.
Technical Context
The APD160VD-E1 integrates two independent Schottky diodes in a single DO-41 axial leaded package, sharing no internal connection - functionally equivalent to two discrete devices. Its guard-ring structure enhances ruggedness against transient stress and improves reliability under repetitive surge conditions.
Designed for high-frequency switching, it exhibits low junction capacitance (~91 pF at 4 V) and fast recovery behavior inherent to Schottky architecture, minimizing switching losses and EMI generation in DC-DC converters and inverters operating above 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage before avalanche breakdown; sets upper limit for input/output voltage rails in buck/boost stages. |
| IF(AV) | 1.0 A - Continuous average forward current rating at TA = +25°C with specified PCB pad layout; derates linearly above +25°C ambient. |
| VF (max) | 0.68 V @ 1 A, +25°C - Directly determines conduction loss (Pcond ≈ 0.68 W per diode at full load), critical for efficiency in low-voltage output stages. |
| IFSM | 35 A (8.3 ms half-sine) - Surge withstand capability enables robustness against inrush and short-circuit transients without failure. |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient on standard FR-4 board; defines required heatsinking margin for +125°C max TJ. |
| TJ Range | –65 to +125 °C - Extended operating junction temperature supports industrial and automotive under-hood environments with minimal derating. |
Pinout & Package
APD160VD-E1 uses the DO-41 axial-leaded plastic package (0.33 g weight), with cathode identified by a band marking on the body. The device contains two isolated Schottky diodes; each has its own anode and cathode terminal - no shared pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input node for first diode | Connects to source of forward current path; polarity-sensitive - reverse connection causes blocking mode. |
| Cathode 1 (Lead 2) | Output node for first diode | Common return path for first diode; marked by cathode band adjacent to this lead. |
| Anode 2 (Lead 3) | Input node for second diode | Electrically isolated from Anode 1; enables independent routing in dual-path topologies like synchronous rectification or dual-output supplies. |
| Cathode 2 (Lead 4) | Output node for second diode | Independent cathode terminal; allows separate grounding or output node assignment per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.68 V max at 1 A ensures <0.7 W conduction loss per diode - critical for >90% efficiency in 3.3 V/5 V DC-DC outputs. |
| Guard-ring protected junction | Enhances edge termination robustness against mechanical stress and voltage transients, improving long-term reliability in vibration-prone applications. |
| +125°C junction rating | Enables operation in sealed enclosures or near heat sources without forced cooling, reducing system-level thermal management complexity. |
| Pb-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and JEDEC J-STD-020 moisture sensitivity Level 1 - supports automated assembly and environmental compliance. |
Applications
| Low Voltage High Frequency Inverters | DC-DC Converters |
|---|---|
Use Scenario: Used in H-bridge output stage of micro-inverters converting 12–48 V DC to 50/60 Hz AC for LED lighting or portable solar systems. IC Role / Device Role / Timing Role: Dual Schottky rectifier providing bidirectional freewheeling paths during PWM dead-time, minimizing voltage spikes and switching losses. Use Value: 0.68 V VF reduces conduction loss by ~30% vs. standard silicon diodes, directly improving inverter efficiency at light-to-moderate loads. | Use Scenario: Employed as output rectifiers in isolated flyback or forward converters delivering 3.3 V/5 V at up to 1 A per rail. IC Role / Device Role / Timing Role: Synchronous rectification replacement for secondary-side diodes, leveraging low VF and fast switching to reduce output ripple and improve transient response. Use Value: 35 A IFSM withstands startup surges and load-dump events common in automotive DC-DC modules without derating. |
| Free Wheeling | Polarity Protection |
Use Scenario: Placed across inductive loads (e.g., solenoids, relays, BLDC motor phases) in industrial control PCBs. IC Role / Device Role / Timing Role: Provides low-loss recirculation path for stored magnetic energy during switch turn-off, limiting voltage overshoot across MOSFETs. Use Value: 80 °C/W RθJA allows direct mounting on standard copper pours - no heatsink needed for ≤1 A continuous freewheeling current. | Use Scenario: Installed in series with power input lines of embedded controllers and sensor nodes to prevent damage from reversed battery or adapter connections. IC Role / Device Role / Timing Role: Unidirectional current gate that blocks reverse polarity while passing forward current with minimal dropout (≤0.68 V). Use Value: Dual-diode configuration permits redundant protection or split-rail input conditioning - e.g., separate protection for VCC and analog supply domains. |

FAQ
Is APD160VD-E1 still in active production?
No. Per Diodes Incorporated's official documentation (DS36972 Rev. 5–4, April 2018), APD160VD-E1 is marked "OBSOLETE – PART DISCONTINUED" with "NO ALTERNATE PART" listed. Aetrix Electronics maintains limited legacy stock for continuity support but does not offer new production builds.
What is the difference between APD160VD-E1 and APD160VD-G1?
Both share identical electrical and thermal specifications. APD160VD-E1 denotes RoHS-compliant finish (lead-free, matte tin annealed), while APD160VD-G1 adds halogen- and antimony-free "Green" packaging per Diodes' definition (<900 ppm Br/Cl, <1000 ppm Sb). Mechanical dimensions and marking differ slightly per ordering code.
Can APD160VD-E1 be used in surface-mount designs?
No. APD160VD-E1 is exclusively offered in the through-hole DO-41 axial package. For surface-mount equivalents, consider Diodes' APD160VRTR-G1 (DO-214AC) variant - same die, different package - which supports reflow soldering and automated placement.
Does APD160VD-E1 require a heatsink in 1 A continuous operation?
Not under typical conditions. With RθJA = 80 °C/W and Pcond ≈ 0.68 W, junction temperature rise is ~54 °C above ambient. At TA = +70°C, TJ ≈ +124°C - within spec. Adequate copper area (≥1 in²) is sufficient; no external heatsink needed unless ambient exceeds +70°C or airflow is restricted.
