Product details
Overview
1N5395S-T from Diodes Incorporated is a 400 V, 1.5 A general-purpose silicon rectifier diode in DO-41 package, featuring 1.1 V forward voltage at 1.5 A, 50 A non-repetitive surge capability, and 5.0 μA reverse leakage at 25°C; used in AC/DC input stage rectification for offline power supplies and industrial control power modules.
For engineers reviewing the 1N5395S-T datasheet, 1N5395S-T pinout, 1N5395S-T application, or 1N5395S-T equivalent, key selection criteria include peak repetitive reverse voltage (400 V), average rectified current derating above 70°C, thermal resistance (25 °C/W junction-to-lead), and DO-41 mechanical compatibility with through-hole PCB layouts.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads; capacitive loads require 20% current derating. Its fast switching behavior enables high-efficiency conversion without snubber circuits in low-frequency SMPS front-ends.
The junction-to-lead thermal resistance of 25 °C/W supports reliable conduction at 1.5 A with minimal heatsinking when leads are maintained at ambient temperature at 9.5 mm from case; total capacitance is 20 pF at 1 MHz and 4 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage before breakdown; sets minimum insulation margin for 230 VAC input designs. |
| IO @ TA=70°C | 1.5 A - Continuous DC output current rating; requires thermal management above ambient 70°C per Fig. 1 derating curve. |
| VFM @ IF=1.5A | 1.1 V - Forward drop determines conduction loss (1.65 W at full load); impacts efficiency and thermal design. |
| IFSM (8.3 ms) | 50 A - Surge withstand capability during cold-start inrush; enables use without series NTC in many applications. |
| IRM @ 25°C | 5.0 μA - Low leakage preserves hold-up time in capacitor-input filters and reduces standby power loss. |
| RθJL | 25 °C/W - Enables direct lead heat sinking; allows >1.2 A continuous operation with 25°C/W ambient-to-lead path. |
| CT @ 1 MHz | 20 pF - Minimal junction capacitance avoids EMI coupling in high-noise rectifier nodes. |
Pinout & Package
DO-41 molded plastic package with axial leads; cathode identified by band. Standard JEDEC DO-41 outline: length 25.4 mm max, body diameter 4.06–5.21 mm, lead diameter 0.71–0.864 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal during forward conduction | Connected to AC source or transformer secondary; must handle full surge current and RMS heating. |
| Cathode | Output terminal during forward conduction; marked with band | Feeds filter capacitor or downstream regulator; polarity reversal causes catastrophic failure. |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching recovery | Enables efficient 50/60 Hz rectification without significant reverse recovery loss or ringing. |
| 50 A surge rating | Withstands repeated cold-start surges in unregulated power supplies without degradation. |
| RoHS-compliant tin finish | Ensures solderability per MIL-STD-202 Method 208 and eliminates lead-based process risks. |
| UL 94V-0 flammability rating | Meets safety standards for enclosed industrial equipment requiring flame-retardant encapsulation. |
Applications
| Industrial AC/DC Power Supply | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 120/230 VAC mains input in open-frame industrial power supplies rated up to 30 W. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC to pulsating DC prior to bulk capacitor filtering. Use Value: 400 V VRRM provides 2× safety margin over 230 VAC peak (325 V), while 1.5 A IO sustains continuous load with minimal derating at 60°C ambient. |
Use Scenario: Bridge or single-diode rectification in constant-current LED drivers for street lighting and signage. IC Role / Device Role / Timing Role: Input rectifier in flyback or buck-derived topologies where low forward drop improves efficiency at partial load. Use Value: 1.1 V VFM reduces conduction loss by ~15% versus legacy 1N4007 (1.3 V), directly improving thermal margin in sealed enclosures. |
| Appliance Motor Control Board | UPS Input Protection Circuit |
Use Scenario: AC line rectification for microcontroller and relay power rails in washing machine or HVAC control boards. IC Role / Device Role / Timing Role: Isolation and polarity enforcement between mains input and low-voltage DC distribution network. Use Value: 5.0 μA IRM minimizes standby current draw, supporting Energy Star compliance for always-on control logic. |
Use Scenario: Reverse-polarity protection and transient clamping in online UPS input stages handling generator-sourced AC. IC Role / Device Role / Timing Role: Back-to-back configuration with another diode to block reverse feed during battery backup mode. Use Value: 50 A IFSM withstands generator waveform anomalies and zero-crossing transients without latch-up or parametric shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007-T | 1000 V VRRM, 1.0 A IO, 1.3 V VFM, DO-41 | Higher voltage margin but lower current and higher conduction loss | Select when >600 V reverse stress is expected; avoid if 1.5 A continuous load exceeds rating. |
| RS1M-T | 1000 V VRRM, 1.0 A IO, 1.3 V VFM, faster recovery (~500 ns), DO-41 | Optimized for higher-frequency rectification; not needed for 50/60 Hz | Prefer only in high-frequency auxiliary supplies; otherwise over-specified and costlier than 1N5395S-T. |
Compared with 1N4007-T and RS1M-T, the 1N5395S-T delivers optimal balance of 400 V blocking, 1.5 A current, and 1.1 V forward drop for standard-line-frequency rectification-reducing both thermal load and bill-of-materials cost where full 1000 V rating is unnecessary.

FAQ
What is the maximum operating temperature for 1N5395S-T?
The 1N5395S-T has an operating junction temperature range of –65°C to +150°C. Its thermal resistance junction-to-lead is 25°C/W, so sustained 1.5 A operation requires the leads to remain near ambient temperature-typically achieved with ≥9.5 mm lead length and no additional heatsinking at ≤70°C ambient.
Is 1N5395S-T compatible with lead-free reflow processes?
Yes-the device features a lead-free, RoHS-compliant tin finish on its terminals and is rated for solderability per MIL-STD-202, Method 208. It supports standard SnPb and lead-free wave and reflow profiles, including peak temperatures up to 260°C for 10 seconds.
Can 1N5395S-T replace 1N4007 in existing designs?
Only if the circuit's peak reverse voltage does not exceed 400 V and average current remains ≤1.5 A. The 1N4007 supports 1000 V but only 1.0 A; substituting 1N5395S-T improves current capacity and reduces forward loss, but compromises voltage margin in 230 VAC+ applications with poor regulation.
Does 1N5395S-T have a specified reverse recovery time?
No-this is a general-purpose rectifier, not a fast-recovery diode. Its datasheet does not specify trr; it is characterized for 50/60 Hz operation and exhibits typical recovery behavior suitable for line-frequency use, not high-frequency switching.
