Product details

Overview

1N4006-E3/73 from Vishay General Semiconductor is a general-purpose plastic rectifier diode in DO-41 package, rated for 800 V peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 1.1 V forward voltage drop at 1.0 A. It serves as a single-junction silicon rectifier in AC-to-DC power supply front-ends, freewheeling paths, and low-frequency converter outputs.

For engineers reviewing the 1N4006-E3/73 datasheet, 1N4006-E3/73 pinout, 1N4006-E3/73 application, or 1N4006-E3/73 equivalent, key selection criteria include verified V_RRM = 800 V, I_F(AV) = 1.0 A, I_FSM = 30 A (8.3 ms), R_θJA = 50 °C/W, and DO-41 mechanical compatibility with standard through-hole PCB layouts.

Technical Context

The 1N4006-E3/73 implements a single PN-junction silicon rectifier structure optimized for 50/60 Hz line-frequency operation. Its design emphasizes high surge robustness (30 A I_FSM, 8.3 ms sine) and low leakage (5.0 μA at 25 °C), with thermal resistance of 50 °C/W junction-to-ambient under standard 0.375" lead length mounting.

It operates across –50 °C to +150 °C junction temperature range and features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing. The cathode is marked by a color band on the molded epoxy DO-41 body meeting UL 94 V-0 flammability rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum repetitive peak reverse voltage; defines safe blocking capability in rectifier bridges or DC-blocking paths
I_F(AV)	1.0 A - Average forward rectified current at 75 °C ambient with 0.375" lead length; sets continuous power-handling limit
V_F	1.1 V - Forward voltage at 1.0 A; determines conduction loss and thermal dissipation in linear rectification
I_R	5.0 μA - Reverse leakage at rated V_DC and 25 °C; critical for low-power standby and high-impedance bias networks
I_FSM	30 A - Non-repetitive surge current (8.3 ms half-sine); enables survival during AC line transients or inrush events
T_J max	+150 °C - Maximum junction temperature; constrains thermal design margin and derating curves
R_θJA	50 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under given power dissipation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4006G	V_RRM = 800 V, same I_F(AV)/V_F, but Pb-free matte tin plating per J-STD-002B instead of E3-class whisker test compliance	No functional difference in rectification; differs only in plating qualification scope	Select 1N4006G if JESD 201 whisker testing is not required and standard Pb-free solderability suffices
STPS1H100	Schottky diode, V_RRM = 100 V, V_F ≈ 0.85 V @ 1 A, I_F(AV) = 1.0 A, but limited to ≤100 V blocking	Lower V_F improves efficiency in low-voltage, high-current DC-DC outputs; unsuitable for 230 VAC rectification	Choose STPS1H100 only for sub-100 V DC applications where reduced conduction loss outweighs lower voltage rating

Compared with 1N4006-E3/73, 1N4006G offers identical electrical performance with alternate plating compliance, while STPS1H100 trades higher voltage capability for lower forward drop-making it viable only in low-V_R DC systems.

FAQ

What is the maximum peak reverse voltage rating for the 1N4006-E3/73?

The 1N4006-E3/73 has a maximum repetitive peak reverse voltage (V_RRM) of 800 V. This rating is confirmed in Vishay's official datasheet (Document Number: 88503) and defines the highest transient reverse voltage the diode can block without breakdown. It is distinct from the 1N4007's 1000 V rating and must not be exceeded in circuit design.

Is the 1N4006-E3/73 RoHS-compliant and lead-free?

Yes, the 1N4006-E3/73 is RoHS-compliant and lead-free. The "E3" suffix indicates compliance with EU RoHS Directive 2011/65/EU and confirms matte tin-plated leads qualified to JESD 201 Class 1A for whisker resistance. It meets J-STD-002 solderability standards and carries UL 94 V-0 flammability certification for its epoxy body.

What is the forward voltage drop of the 1N4006-E3/73 at rated current?

The 1N4006-E3/73 exhibits a maximum instantaneous forward voltage (V_F) of 1.1 V at 1.0 A forward current and 25 °C ambient, per Vishay's Electrical Characteristics table. This value is measured under pulsed conditions (300 μs, 1 % duty cycle) and represents typical conduction loss during steady-state operation in rectifier applications.

Can the 1N4006-E3/73 replace the 1N4007 in a 230 VAC power supply?

The 1N4006-E3/73 (V_RRM = 800 V) may be used in 230 VAC applications where design margin allows, but it is not a guaranteed replacement for the 1N4007 (V_RRM = 1000 V). For universal-input supplies or environments with high line transients, the 1N4007 provides greater safety margin; substituting 1N4006-E3/73 requires verification of worst-case peak reverse stress.

What is the thermal resistance and maximum junction temperature of the 1N4006-E3/73?

The 1N4006-E3/73 has a typical junction-to-ambient thermal resistance (R_θJA) of 50 °C/W when mounted with 0.375" (9.5 mm) lead length on a PCB, and a maximum operating junction temperature (T_J) of +150 °C. These values govern thermal derating-e.g., at 75 °C ambient, I_F(AV) remains 1.0 A, but must be reduced above that temperature per the forward current derating curve.
