Product details

Overview

1N4007L-T from Diodes Incorporated is a general-purpose silicon rectifier diode in DO-41 package, rated for 1000 V peak repetitive reverse voltage and 1.0 A average forward current at +75°C ambient, with 30 A non-repetitive surge capability and 1.0 V forward voltage at 1.0 A. It serves as a primary AC-to-DC conversion element in low-frequency power supplies, battery chargers, and input stage protection circuits.

For engineers reviewing the 1N4007L-T datasheet, 1N4007L-T pinout, 1N4007L-T application, or 1N4007L-T equivalent, key selection criteria include its 1000 V blocking rating, thermal resistance of 100 K/W, low 5.0 µA reverse leakage at 25°C, DO-41 mechanical compatibility, and RoHS-compliant bright tin plating.

Technical Context

This axial-leaded rectifier uses a diffused PN junction optimized for high surge tolerance and stable DC blocking under 60 Hz half-wave operation. Its 1.0 V forward drop at rated current and 15 pF junction capacitance (measured at 1 MHz, 4 V reverse bias) reflect trade-offs between conduction loss and switching speed in line-frequency applications.

The device operates across –65°C to +150°C junction temperature range, with thermal derating beginning above +75°C ambient per Figure 1. It is explicitly marked "NOT RECOMMENDED FOR NEW DESIGN" in favor of S1A–S1M series, indicating legacy status while maintaining full electrical compliance per DS28002 Rev. 9-3.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Maximum peak reverse voltage the diode blocks without breakdown; defines safe AC input voltage ceiling in bridge or half-wave rectifiers.
I_O	1.0 A @ T_A = +75°C - Continuous DC output current capability when leads are held at ambient at 9.5 mm from case; requires heatsinking or airflow above this temperature.
I_FSM	30 A (8.3 ms half-sine) - Surge withstand for inrush or fault conditions; critical for transformer-coupled or capacitive-input supply robustness.
V_F	1.0 V @ I_F = 1.0 A - Forward conduction loss determining power dissipation (1.0 W typical at full load); impacts thermal design and efficiency.
I_R	5.0 µA @ 25°C - Reverse leakage defining off-state power loss and isolation integrity in high-impedance or precision hold circuits.
R_θJA	100 K/W - Junction-to-ambient thermal resistance; used to calculate junction temperature rise (ΔT = P_D × R_θJA) for reliability margining.
T_J Range	–65°C to +150°C - Operating junction temperature envelope; enables use in industrial enclosures or automotive under-hood environments with proper layout.

Pinout & Package

DO-41 molded plastic package with axial leads; cathode identified by a single band near one lead end. Case meets UL 94V-0 flammability rating and J-STD-020D Level 1 moisture sensitivity. Weight: ~0.30 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unbanded end)	Forward current entry point	Connected to AC source or transformer secondary; must handle full surge current and thermal stress during conduction.
Cathode (banded end)	Forward current exit / reverse voltage reference	Connected to load or filter capacitor; polarity marking ensures correct orientation in PCB layout and prevents reverse breakdown.

Key Features

Feature	Design Value
Diffused junction construction	Enables uniform electric field distribution and reliable 30 A surge handling without localized hot-spot failure.
Low forward voltage (1.0 V @ 1 A)	Minimizes conduction loss and self-heating in continuous-duty linear power supplies and battery charging circuits.
1000 V peak reverse rating	Supports direct rectification of 700 V RMS line inputs (e.g., 480 VAC industrial systems) with safety margin.
Bright tin-plated leads	Ensures solderability per MIL-STD-202 Method 208 and RoHS compliance without lead-free reflow complications.

Applications

AC/DC Power Adapter

Industrial Motor Control Input Stage

Use Scenario: Converts 120/230 VAC mains to unregulated DC for wall adapters powering consumer electronics.

IC Role / Device Role / Timing Role: Primary rectifier in single-phase half-wave or bridge configuration; handles full line current and surge transients.

Use Value: 1000 V rating provides margin against line spikes; 30 A surge rating absorbs transformer inrush without failure.

Use Scenario: Rectifies AC control power feeding logic circuitry or auxiliary relays in motor drives.

IC Role / Device Role / Timing Role: Isolation and polarity enforcement diode on low-power auxiliary supply rails.

Use Value: Low 5.0 µA reverse leakage preserves hold-up time in capacitor-input filters; DO-41 form factor fits standard through-hole layouts.

LED Lamp Driver Input Protection

Automotive Battery Charger Input Stage

Use Scenario: Blocks reverse polarity and rectifies AC input in low-cost LED retrofit lamps.

IC Role / Device Role / Timing Role: Polarity guard and basic rectifier in non-isolated buck-derived topologies.

Use Value: Cathode band marking simplifies automated assembly verification; RoHS-compliant finish meets lighting industry requirements.

Use Scenario: Converts alternator or external AC source output to charge 12 V lead-acid batteries.

IC Role / Device Role / Timing Role: Main rectifier in half-wave or center-tapped transformer configurations.

Use Value: –65°C to +150°C operating range supports under-hood deployment; 100 K/W thermal resistance guides heatsink sizing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4007G-T	Same electrical specs; green compound (halogen-free) molding vs. standard DO-41 plastic.	No functional difference; selected where halogen-free compliance is mandated.	Direct replacement if halogen-free certification required; identical thermal and electrical behavior.
S1M-T	1000 V V_RRM, 1.0 A I_O, but surface-mount SMB package; lower R_θJA (50 K/W), faster recovery (~2 µs).	Designed for automated SMT assembly; unsuitable for through-hole boards without adapter.	Preferred for new designs requiring higher efficiency, smaller footprint, or improved thermal performance.

Compared with 1N4007L-T, the S1M-T offers superior thermal performance and SMT compatibility but requires PCB redesign, while 1N4007G-T maintains identical form-fit-function with halogen-free material-making it ideal for eco-regulated legacy upgrades.

FAQ

What does the 'L' suffix in 1N4007L-T signify?

The 'L' denotes Diodes Incorporated's specific internal part variant designation for the 1N4007 in tape-and-reel packaging ('T') with standard DO-41 plastic case and bright tin plating. It is not a performance or specification modifier-electrical parameters match the base 1N4007 per DS28002 Rev. 9-3.

Is 1N4007L-T suitable for high-frequency switching applications?

No. With a junction capacitance of 15 pF and unspecified reverse recovery time (typical for legacy rectifiers), it is intended only for 50/60 Hz line-frequency rectification. High-frequency use causes excessive switching loss and potential thermal runaway; S1M-T or UF4007 are appropriate alternatives.

Why is 1N4007L-T marked 'NOT RECOMMENDED FOR NEW DESIGN'?

Diodes Incorporated issued this notice because newer alternatives like the S1A–S1M series offer better thermal resistance (50 K/W vs. 100 K/W), tighter parameter distributions, halogen-free options, and SMT compatibility-without increasing cost. The 1N4007L-T remains fully qualified for repair and legacy production.

Can 1N4007L-T be substituted for 1N4007-B in a design?

Yes-both share identical electrical specifications and DO-41 package. The '-T' suffix indicates 5K tape-and-reel packaging for automated placement; '-B' is 1K bulk. Mechanical fit, thermal behavior, and soldering profile are identical; only handling and assembly method differ.
