Product details

Overview

ES1B-13-F from Diodes Incorporated is a 1.0A surface-mount super-fast rectifier diode in SMA package, rated for 100V peak repetitive reverse voltage (V_RRM), 25ns reverse recovery time (t_RR), and 0.92V forward voltage at 1.0A (V_FM). It serves as primary AC/DC input rectifier in compact offline power supplies for consumer adapters and industrial SMPS.

For engineers reviewing the ES1B-13-F datasheet, ES1B-13-F pinout, ES1B-13-F application, or ES1B-13-F equivalent, key selection criteria include its 100V blocking rating, sub-30ns recovery performance, thermal resistance of 25°C/W, RoHS-compliant matte tin terminations, and suitability for automated SMT assembly on FR-4 PCBs with minimal copper pad area.

Technical Context

This super-fast rectifier employs glass-passivated silicon die to achieve rapid minority-carrier recombination, enabling efficient high-frequency switching operation up to 100 kHz. Its 25 ns reverse recovery time minimizes switching losses during turn-off transitions in flyback and buck-derived topologies.

The device operates across –55°C to +150°C junction temperature range with 30 A non-repetitive surge capability (8.3 ms half-sine), supporting robust line transient handling in unregulated input stages. Thermal resistance is specified at 25°C/W when mounted on a 5.0 mm² copper pad per JEDEC standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage before breakdown; sets usable input voltage range in 85–265 VAC designs.
t_RR	25 ns - Measured at I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A; enables low-loss operation in 50–100 kHz SMPS.
V_FM	0.92 V @ I_F = 1.0 A - Forward drop directly impacts conduction loss and thermal rise in continuous conduction mode.
I_O	1.0 A @ T_T = +110°C - Average rectified current rating under real-world thermal conditions on standard PCB layout.
R_θJT	25 °C/W - Junction-to-terminal thermal resistance with 5.0 mm² copper pad; determines required heatsinking for 1.0 A load.
I_FSM	30 A (8.3 ms) - Surge rating supports cold-start inrush and lightning-induced line transients without failure.
C_T	20 pF @ 1 MHz, 4 V_R - Junction capacitance affects EMI generation and snubber design in high-dv/dt applications.

Pinout & Package

ES1B-13-F is housed in an SMA (DO-214AC) surface-mount plastic package with molded UL 94V-0 housing and matte tin–annealed copper leadframe terminals. Polarity is indicated by a cathode band on the case body.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC input or transformer secondary; must withstand full surge current and reverse voltage stress.
Cathode	Forward current exit / reverse blocking node	Connected to bulk capacitor or output rail; carries full DC output current and defines reverse voltage reference.

Key Features

Feature	Design Value
Glass passivated die	Eliminates surface leakage paths and improves long-term reliability under humid or contaminated environments.
Super-fast 25 ns recovery	Reduces reverse recovery charge (Q_rr) and associated switching losses in high-frequency converters.
30 A surge rating	Supports repeated cold-start events and line surges without parametric shift or catastrophic failure.
Lead-free & halogen-free	Complies with RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity; eliminates post-reflow cleaning requirements.

Applications

Use Scenario: 36–75 W open-frame power supplies for PLC I/O modules and motor drives.

IC Role / Device Role / Timing Role: Input rectifier in discontinuous conduction mode (DCM) flyback converters operating at 65 kHz.

Use Value: 25 ns t_RR limits reverse recovery ringing and EMI filter component count.

USB-C PD Power Delivery Front-End

LED Driver Auxiliary Supply

Use Scenario: Secondary-side auxiliary supply in multi-output USB-C PD controllers for gate drive and logic biasing.

IC Role / Device Role / Timing Role: High-efficiency rectifier feeding isolated 12 V bias rail from auxiliary winding.

Use Value: 1.0 A rating and 25°C/W R_θJT enable stable operation without heatsink in space-constrained layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R04	100 V V_RRM, 30 ns t_RR, 0.95 V V_F @ 1 A, TO-277 package	Higher thermal resistance (35°C/W); requires larger pad or heatsink for same current	Prefer where higher surge margin (50 A) outweighs footprint penalty and thermal derating.
MBR1100	100 V V_RRM, Schottky architecture, 0.75 V V_F @ 1 A, but 100 µA I_R @ 100 V	No reverse recovery (t_RR = 0), but higher leakage compromises high-temp hold-up performance	Select only in <85°C ambient applications where ultra-low V_F dominates over leakage-driven standby loss.

Compared with STTH1R04 and MBR1100, ES1B-13-F delivers optimal balance of speed (25 ns), low forward loss (0.92 V), and low leakage (200 µA @ 125°C), making it preferred for thermally constrained, high-efficiency 5–30 W offline supplies.

FAQ

What is the maximum junction temperature for ES1B-13-F?

The absolute maximum junction temperature is +150°C, with continuous operation rated up to +110°C terminal temperature. Derating curves in the datasheet show 1.0 A average current is maintained up to +110°C; beyond that, current must be linearly reduced to prevent exceeding 150°C junction limit.

Is ES1B-13-F compatible with lead-free reflow profiles?

Yes - ES1B-13-F uses matte tin–annealed copper leadframe terminations qualified for standard Pb-free reflow (JEDEC J-STD-020 Level 1). Peak temperature tolerance is 260°C for 10 seconds, matching IPC/JEDEC Class 3 requirements without delamination or solder joint degradation.

How does the 25 ns reverse recovery time impact EMI in a flyback converter?

A 25 ns t_RR reduces reverse recovery charge (Q_rr) and associated high-frequency ringing during turn-off, lowering common-mode noise amplitude and easing compliance with CISPR-32 Class B conducted EMI limits without oversized snubbers or ferrite beads.

Can ES1B-13-F replace ES1A-13-F in existing designs?

Yes - both share identical SMA package, pinout, thermal characteristics, and surge rating. ES1B-13-F offers higher V_RRM (100 V vs. 50 V) and slightly higher V_FM (0.92 V vs. 0.90 V at 1 A), enabling direct substitution where 100 V blocking is required without layout changes.
