Product details
Overview
RS07B-M-18 from Vishay Semiconductors is a surface-mount fast recovery rectifier diode in the eSMP® SMF (DO-219AB) package, rated for 100 V repetitive peak reverse voltage, 1.4 A average forward current at 65 °C lead temperature, and 150 ns reverse recovery time. It delivers low forward voltage (1.15 V at 0.7 A), <10 µA reverse leakage at 25 °C, and is optimized for high-efficiency AC/DC front-end and DC/DC converter stages in compact power supplies.
For engineers reviewing the RS07B-M-18 datasheet, RS07B-M-18 pinout, RS07B-M-18 application, or RS07B-M-18 equivalent, key selection criteria include its 100 V VRRM, 150 ns trr, SOD-123W-compatible SMF package, halogen-free RoHS-compliant construction, and suitability for automated reflow and wave soldering in space-constrained industrial and consumer power designs.
Technical Context
The RS07B-M-18 employs a planar epitaxial silicon junction with glass passivation to achieve fast switching (trr = 150 ns) and stable reverse characteristics across -55 °C to +150 °C. Its thermal resistance junction-to-lead is 30 K/W, enabling efficient heat transfer to PCB copper pads under continuous 1.4 A load at TL = 65 °C.
Designed as a single-diode configuration with cathode band marking, it supports unidirectional conduction in bridge rectifiers, flyback snubbers, and OR-ing circuits. The device meets JESD201 Class 2 whisker test and J-STD-020 MSL Level 1 (260 °C peak reflow), confirming robustness for high-volume SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking capability without avalanche breakdown |
| IF(AV) | 1.4 A at TL = 65 °C - Continuous forward current rating with adequate PCB copper thermal relief |
| VF | 1.15 V at IF = 0.7 A - Low conduction loss enabling >92 % efficiency in 5–24 V output converters |
| trr | 150 ns - Fast recovery minimizes switching losses and EMI in 50–500 kHz SMPS topologies |
| RthJL | 30 K/W - Enables direct thermal coupling to PCB leads for passive cooling without heatsinks |

| SOD-123W footprint compatibility | Enables drop-in replacement or layout reuse with existing SOD-123W-based designs and pick-and-place tooling |
| AEC-Q101 not qualified (M3 version) | Differentiated from HM3 variant; intended for industrial/consumer use, not automotive applications |
Applications
| AC/DC Adapter Front-End | USB PD Power Delivery Module |
|---|---|
Use Scenario: Rectifying 50/60 Hz or high-frequency AC input in compact wall adapters delivering 5–65 W. IC Role / Device Role / Timing Role: Primary-side unidirectional conduction element in full-wave or voltage-doubler configurations.

IC Role / Device Role / Timing Role: High-reliability rectifier in capacitor-input filter stage subjected to frequent on/off cycling. Use Value: JESD201 Class 2 whisker resistance and glass passivation prevent parametric drift and open-circuit failure after 10,000+ thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04U | TO-277A package (larger), 400 V VRRM, 1.05 V VF @ 1 A, 35 ns trr | Higher voltage rating and faster recovery, but 3× larger footprint and higher cost | Select when >100 V blocking or <50 ns trr is required; not pin-compatible |
| ON Semiconductor FFPF10W60DTU | TO-220FP package, 600 V VRRM, 1.75 V VF @ 10 A, 50 ns trr | Higher current/power handling, but through-hole mounting and thermal design overhead | Choose for >5 A average current or forced-air-cooled industrial PSUs; incompatible footprint |
Compared with STTH1R04U and FFPF10W60DTU, the RS07B-M-18 offers optimal balance of compact SMF packaging, 100 V rating, and 150 ns recovery for cost-sensitive, space-limited 1–2 A power rails-without requiring PCB redesign or thermal derating penalties.

FAQ
What is the maximum junction temperature rating for the RS07B-M-18?
The RS07B-M-18 has an operating junction temperature range of -55 °C to +150 °C, as specified in the Vishay datasheet Rev. 2.1. This allows reliable operation in sealed enclosures or high-ambient environments such as industrial control cabinets. The RS07B-M-18 maintains stable electrical parameters-including 10 µA reverse leakage at 25 °C and 50 µA at 125 °C-within this full range.
Is the RS07B-M-18 RoHS-compliant and halogen-free?
Yes, the RS07B-M-18 is halogen-free and RoHS-compliant per its base ordering code suffix "-M3". It meets EU Directive 2011/65/EU and satisfies Vishay's material categorization per document 99912. The RS07B-M-18 does not contain brominated flame retardants or chlorine-based compounds above threshold limits.
Does the RS07B-M-18 have AEC-Q101 qualification?
No, the RS07B-M-18 is not AEC-Q101 qualified. That qualification applies only to the RS07B-HM3 variant (e.g., RS07B-HM3-18). The RS07B-M-18 is intended for industrial and consumer applications; for automotive use, engineers must specify the HM3 version and verify full AEC-Q101 test report compliance.
What is the recommended PCB footprint for the RS07B-M-18?
Vishay specifies a footprint with 1.3 mm × 1.3 mm copper pads for each terminal, aligned to the SMF (DO-219AB) outline. The RS07B-M-18 datasheet Figure on page 5 shows exact dimensions: 2.9 mm length, 1.9 mm width, and 1.08 mm height. Use this layout-not SOD-123-when optimizing thermal performance, as RthJL = 30 K/W depends on proper pad sizing.
Can the RS07B-M-18 replace a standard 1N4007 in a new design?
No-the RS07B-M-18 is not a direct replacement for the 1N4007. While both are rectifiers, the RS07B-M-18 is a fast recovery diode (150 ns trr) rated for 100 V and 1.4 A, whereas the 1N4007 is a general-purpose rectifier (30 µs trr) rated for 1000 V and 1 A. Substituting RS07B-M-18 in a 1N4007 circuit risks reverse voltage overstress; always verify VRRM, trr, and thermal design for the RS07B-M-18.
