Product details

Overview

SB160-B from Diodes Incorporated is a 1.0A, 60V peak repetitive reverse voltage Schottky barrier rectifier in DO-41 plastic package, featuring 0.50V forward voltage at 1.0A, 40A non-repetitive surge capability, and junction-to-lead thermal resistance of 15°C/W. It is used for polarity protection and free-wheeling in low-voltage DC/DC converters.

For engineers reviewing the SB160-B datasheet, SB160-B pinout, SB160-B application, or SB160-B equivalent, key selection criteria include forward voltage drop at rated current, surge robustness under inductive switching, thermal performance in lead-mounted configurations, and RoHS-compliant tin-plated leads for automated soldering.

Technical Context

This Schottky rectifier uses a guard ring die construction to enhance transient protection and reduce leakage during reverse-biased operation. Its low V_F and fast recovery enable high-efficiency operation in 60Hz–1MHz switching applications without minority-carrier storage delay.

The device is rated for continuous average output current of 1.0A under resistive or inductive loads with 9.5mm lead length, and supports capacitive-load derating (−20% I_O). Junction temperature range spans −65°C to +125°C, with storage up to +150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum peak reverse voltage before breakdown; sets safe operating limit in polarity protection circuits.
I_O	1.0 A - Average rectified current at TA = 25°C with 9.5 mm lead length; defines steady-state power handling.
V_FM @ 1.0A	0.50 V - Forward voltage drop at rated DC current; directly determines conduction loss and thermal rise.
I_FSM	40 A - Non-repetitive surge rating (8.3 ms half-sine); supports inductive kickback in relay or motor drive freewheeling.
R_JL	15 °C/W - Junction-to-lead thermal resistance; enables accurate temperature estimation when mounted on PCB copper pour or heatsinked leads.
I_RM @ 25°C	0.5 mA - Peak reverse leakage at rated V_R; impacts standby power in battery-powered polarity guards.

Pinout & Package

DO-41 plastic package: axial-leaded, molded black epoxy case, UL 94V-0 rated, with cathode band marking. Leads are bright tin-plated and MIL-STD-202 solderable.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unmarked end)	Forward current entry point	Connected to input/source side in rectification; must handle full load current and surge transients.
Cathode (banded end)	Forward current exit / reverse-blocking terminal	Connected to output/load; cathode band orientation ensures correct polarity in PCB silkscreen and assembly.

Key Features

Feature	Design Value
Guard ring die construction	Improves transient immunity and reduces IR drift under voltage stress, critical for automotive load-dump survival.
Low V_F (0.50 V @ 1A)	Reduces conduction loss by >30% vs. standard PN rectifiers, lowering thermal demand in space-constrained adapters.
40A surge rating	Withstands repetitive inductive turn-off spikes without degradation-validated per JEDEC 8.3ms half-sine test.
RoHS-compliant tin plating	Enables lead-free reflow compatibility and eliminates post-solder cleaning for high-volume SMT-compatible through-hole assembly.

Applications

DC/DC Converter Output Rectification

Automotive Polarity Protection

Use Scenario: Secondary-side rectification in 5–24V isolated flyback or forward converters.

IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC, operating at 100kHz–1MHz.

Use Value: 0.50V V_F minimizes power loss and improves efficiency over silicon diodes, reducing heatsink requirements.

Use Scenario: Reverse-voltage blocking at vehicle battery input (12V/24V systems).

IC Role / Device Role / Timing Role: Passive protection element placed in series with power rail to prevent damage from incorrect battery connection.

Use Value: 60V V_RRM provides 2× margin over 24V nominal systems, while 40A surge rating handles jump-start transients.

Industrial Free-Wheeling Diode

AC-DC Adapter Input Bridge Leg

Use Scenario: Snubbing inductive energy from solenoids, relays, or stepper motor windings.

IC Role / Device Role / Timing Role: Fast-recovery path for stored magnetic energy during switch-off, preventing MOSFET drain overvoltage.

Use Value: Schottky architecture eliminates reverse recovery time, eliminating switching noise and EMI in 20–100kHz control loops.

Use Scenario: One leg of a single-phase bridge rectifier in universal-input (85–265VAC) offline adapters.

IC Role / Device Role / Timing Role: Half-wave rectifying element conducting during positive half-cycles; paired with three others for full-wave operation.

Use Value: Low R_JA (50°C/W) and R_JL (15°C/W) allow reliable operation without forced air, supporting compact open-frame designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB160-T (Diodes Inc.)	Same die and specs, but supplied in 5K tape-and-reel format instead of 1K bulk.	Optimized for automated pick-and-place; not suitable for manual prototyping or low-volume hand-soldering.	Select SB160-T for high-volume production lines requiring reel-fed placement; SB160-B remains optimal for engineering samples and repair stock.
SS16 (ON Semiconductor)	Identical 60V/1A rating and DO-41 package, but V_F = 0.70V @ 1A (vs. 0.50V), and I_FSM = 30A (vs. 40A).	Higher conduction loss and lower surge margin reduce suitability in thermally constrained or high-transient environments.	Choose SS16 only if SB160-B is unavailable and system-level testing confirms acceptable thermal rise and surge margin.

Compared with SB160-T and SS16, SB160-B offers the lowest forward voltage and highest surge rating in its form factor, making it preferred for thermally sensitive or transient-heavy applications where bulk packaging is acceptable.

FAQ

What is the maximum allowable junction temperature for SB160-B?

The SB160-B has an operating junction temperature range of −65°C to +125°C. Exceeding +125°C risks parametric shift and accelerated degradation; thermal design must ensure T_J stays within this limit using measured R_JL = 15°C/W and ambient conditions.

Can SB160-B replace a standard PN rectifier like 1N4007?

No-SB160-B is not a direct replacement for 1N4007. While both are DO-41 diodes, SB160-B is a Schottky with 60V V_RRM and 0.50V V_F, whereas 1N4007 is a PN diode with 1000V V_RRM and ~1.1V V_F. Substitution requires verifying reverse voltage margin and thermal impact in the target circuit.

Is SB160-B suitable for use in a capacitive-input filter?

Yes, but with 20% derating of average current (to 0.8A). The datasheet explicitly states that for capacitive loads, I_O must be reduced by 20% due to higher RMS current and peak stress on the die, which affects long-term reliability and thermal performance.

Does SB160-B have a specified reverse recovery time (t_rr)?

No-SB160-B is a Schottky barrier rectifier and exhibits no minority-carrier storage; therefore, t_rr is effectively zero. This eliminates reverse recovery loss and associated EMI, distinguishing it from PN diodes like 1N5819, which specify t_rr in nanoseconds.
