Product details

Overview

SB160-E3/53 from Vishay General Semiconductor is a 60 V, 1.0 A Schottky barrier plastic rectifier in DO-41 package, featuring 0.65 V forward voltage at 1.0 A, 50 A peak surge current, and operation up to +150 °C junction temperature-used in DC/DC converters for efficient low-loss freewheeling.

For engineers reviewing the SB160-E3/53 datasheet, SB160-E3/53 pinout, SB160-E3/53 application, or SB160-E3/53 equivalent, key selection criteria include reverse voltage rating, thermal derating behavior, forward voltage drop at operating current, and DO-41 mechanical compatibility with through-hole PCB layouts.

Technical Context

This device implements a single-die Schottky barrier structure with guardring overvoltage protection, enabling high dV/dt capability (10,000 V/μs) and stable reverse leakage (<5.0 mA at 100 °C). Its low R_θJL of 15 °C/W supports sustained 1.0 A average conduction without active cooling.

The SB160-E3/53 operates across –65 °C to +150 °C junction range and maintains <0.65 V VF under 1.0 A DC load at 25 °C, with thermal resistance to ambient (R_θJA) rated at 50 °C/W on standard 0.375" lead length PCB mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - blocks up to 60 V repetitive reverse voltage, suitable for 48 V system bus polarity protection
I_F(AV)	1.0 A - continuous forward current rating at 0.375" lead length, defines max steady-state power handling
V_F @ 1.0 A	0.65 V - low conduction loss enables >92 % efficiency in 5–12 V DC/DC output stages
I_FSM	50 A - withstands 8.3 ms half-sine surge, critical for inductive load turn-off transients
T_J max.	+150 °C - extended junction rating allows operation in sealed enclosures or high-ambient industrial environments
dV/dt	10,000 V/μs - high rate-of-change immunity prevents false turn-on in fast-switching SMPS circuits

Pinout & Package

Package: DO-41 (DO-204AL), axial-leaded, epoxy-molded case with UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode indicated by color band.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., switch node in buck converter); accepts 1.0 A continuous
Cathode	Forward current exit / reverse blocking terminal	Marked with color band; ties to higher-potential rail (e.g., output capacitor positive); blocks 60 V reverse

Key Features

Feature	Design Value
Guardring overvoltage protection	Prevents localized avalanche breakdown during transient overvoltage, improving reliability in unregulated input stages
Low 0.65 V forward voltage	Reduces conduction loss by ~40 % vs. comparable PN rectifiers, lowering thermal stress in compact layouts
High 50 A surge rating	Supports repeated inrush events in motor drive freewheeling paths without degradation
150 °C maximum junction temperature	Enables use in thermally constrained spaces where heatsinking is impractical, such as sealed power modules

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS16-E3/57T	Same DO-41 package, 60 V V_RRM, but 0.75 V V_F @ 1.0 A and 30 A I_FSM	Lower surge tolerance and higher conduction loss reduce suitability in high-transient or high-efficiency designs	Acceptable where cost sensitivity outweighs 0.10 V V_F penalty and 50 A surge is not required
1N5819TR	DO-41, 40 V V_RRM, 1.0 A I_F(AV), 0.475 V V_F @ 1.0 A, 25 A I_FSM	Insufficient reverse voltage margin for 48 V systems; limited to ≤36 V applications	Only viable in sub-40 V designs where lowest possible V_F is prioritized over voltage headroom

Compared with SS16-E3/57T and 1N5819TR, the SB160-E3/53 delivers superior surge robustness and system-level voltage margin while maintaining competitive forward loss-making it optimal for industrial 48 V DC/DC and polarity protection where reliability under transient stress is critical.

FAQ

What is the maximum junction temperature rating for SB160-E3/53?

The SB160-E3/53 has a maximum junction temperature (T_J) rating of +150 °C, allowing operation in thermally demanding environments such as enclosed power supplies or high-ambient industrial settings. This rating is confirmed in the Vishay document 88715 and applies under specified mounting conditions with 0.375" lead length. The SB160-E3/53 must be derated per the forward current derating curve above 75 °C ambient.

Does SB160-E3/53 have a RoHS-compliant construction?

Yes, the SB160-E3/53 is RoHS-compliant, as indicated by its "E3" suffix per Vishay's ordering nomenclature. It meets JEDEC JESD201 Class 1A whisker testing and uses matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The molding compound also complies with UL 94 V-0 flammability requirements.

What is the forward voltage drop of SB160-E3/53 at 1.0 A?

The SB160-E3/53 exhibits a maximum instantaneous forward voltage (V_F) of 0.65 V at 1.0 A and 25 °C, per Vishay document 88715. This value increases with temperature and current; at 100 °C junction, V_F remains below 0.55 V at same current. The low V_F directly reduces conduction losses in power stage design.

Can SB160-E3/53 replace SB150-E3/53 in a 50 V application?

Yes, SB160-E3/53 can replace SB150-E3/53 in a 50 V application because its 60 V V_RRM provides 10 V margin above the 50 V blocking requirement, improving safety factor against transients. Both share identical DO-41 packaging, thermal characteristics, and forward conduction behavior-no layout or thermal redesign is needed for drop-in substitution.

What is the peak forward surge current rating for SB160-E3/53?

The SB160-E3/53 is rated for a non-repetitive peak forward surge current (I_FSM) of 50 A for an 8.3 ms half-sine wave, as specified in Vishay document 88715. This rating ensures robustness against inrush currents and inductive kickback in motor drives and switching regulators-critical for field reliability in industrial equipment using the SB160-E3/53.
