Product details
Overview
SS16HM3_B/I from Vishay General Semiconductor is a surface-mount Schottky barrier rectifier in SMA (DO-214AC) package, rated for 60 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 40 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.75 V at 1.0 A), high efficiency, and AEC-Q101 qualification - ideal for DC/DC converters and polarity protection in automotive power modules.
For engineers reviewing the SS16HM3_B/I datasheet, SS16HM3_B/I pinout, SS16HM3_B/I application, or SS16HM3_B/I equivalent, key selection criteria include its halogen-free RoHS-compliant construction, MSL Level 1 rating (260 °C peak reflow), 150 °C max junction temperature, and cathode-band polarity marking - all critical for high-reliability, thermally constrained board designs.
Technical Context
This Schottky rectifier uses a planar guardring structure to enhance overvoltage robustness and suppress leakage under transient stress. Its low VF (0.75 V @ 1.0 A) and high IFSM (40 A) enable efficient freewheeling in synchronous buck topologies with minimal conduction loss and thermal rise.
The device operates across -65 °C to +150 °C junction temperature range and exhibits RθJA = 88 °C/W (PCB-mounted on 5.0 mm × 5.0 mm copper pad), supporting stable thermal performance in compact, high-density power stages without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - supports input rails up to 42 V DC blocking in automotive 36 V systems |
| IF(AV) | 1.0 A - sustains continuous output current in sub-10 W DC/DC converters |
| VF @ 1.0 A | 0.75 V - reduces conduction loss to ≤0.75 W per diode, easing thermal design |
| IFSM | 40 A - withstands startup surges and load-dump transients without failure |
| TJ max | +150 °C - enables operation in under-hood environments without derating |
| MSL Level | Level 1 (J-STD-020) - allows single-pass reflow at 260 °C peak without moisture sensitivity concerns |
| AEC-Q101 | Qualified - certified for automotive power electronics per stress test requirements |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must handle full IF(AV) and IFSM |
| 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 bias |
Key Features
| Feature | Design Value |
|---|---|
| Guardring overvoltage protection | Prevents premature avalanche breakdown during line transients, improving system-level surge immunity |
| Halogen-free, RoHS-compliant construction | Meets automotive environmental compliance (e.g., ELV, REACH) without compromising thermal or electrical performance |
| Low thermal resistance (RθJL = 28 °C/W) | Enables direct heat transfer to PCB copper, reducing need for thermal vias in space-constrained layouts |
| 10,000 V/μs dV/dt rating | Ensures reliable commutation in fast-switching SMPS without false turn-on or oscillation |
Applications
| Automotive DC/DC Converters | Polarity Protection Circuits |
|---|---|
Use Scenario: Step-down conversion from 12 V or 24 V battery to 3.3 V/5 V for infotainment ECUs. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck regulator, conducting during low-side FET off-time. Use Value: 0.75 V VF minimizes power loss and thermal stress, while AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime. | Use Scenario: Reverse-voltage protection at power input of telematics control units. IC Role / Device Role / Timing Role: Series-connected Schottky rectifier blocking reverse current during battery misconnection. Use Value: 60 V VRRM accommodates load-dump spikes up to 40 V, and low VF avoids excessive voltage drop in normal operation. |
| High-Frequency Inverters | Industrial Sensor Power Supplies |
Use Scenario: Output rectification in 100–500 kHz isolated flyback inverters for LED drivers. IC Role / Device Role / Timing Role: Output rectifier handling high-frequency AC-to-DC conversion with minimal switching loss. Use Value: Fast recovery (inherent to Schottky) and 10,000 V/μs dV/dt rating prevent reverse recovery ringing and EMI generation. | Use Scenario: Input-stage rectification in 24 V industrial sensor nodes with wide ambient temperature range. IC Role / Device Role / Timing Role: Primary AC/DC or DC/DC input protection and rectification before LDO regulation. Use Value: -65 °C to +150 °C operating range ensures functionality in unheated enclosures; halogen-free material meets industrial safety standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16HE3_B/I | RoHS-compliant but not halogen-free; same VRRM, VF, and AEC-Q101 status | Acceptable where halogen content is unrestricted (e.g., commercial-grade modules) | Select SS16HE3_B/I only if halogen-free requirement is waived; otherwise SS16HM3_B/I is mandatory for automotive Tier 1 specs. |
| MBR160F-E3/5AT | Same SMA package, 60 V VRRM, but VF = 0.82 V @ 1.0 A and no AEC-Q101 qualification | Suitable for cost-sensitive industrial power supplies where automotive qualification is unnecessary | Choose MBR160F-E3/5AT for non-automotive use with relaxed thermal and qualification requirements; SS16HM3_B/I remains required for AEC-Q101 compliance. |
Compared with SS16HE3_B/I and MBR160F-E3/5AT, SS16HM3_B/I uniquely combines halogen-free construction, AEC-Q101 qualification, and 0.75 V forward drop - making it the only option meeting Tier 1 automotive material and reliability mandates without trade-offs in electrical performance.

FAQ
What is the maximum junction temperature rating for SS16HM3_B/I?
The SS16HM3_B/I has a maximum junction temperature (TJ) of +150 °C, verified per Vishay Document Number 88746. This rating allows uninterrupted operation in under-hood automotive environments and high-ambient industrial settings without thermal shutdown. The SS16HM3_B/I maintains specified electrical characteristics up to this limit when mounted on a 5.0 mm × 5.0 mm copper pad.
Is SS16HM3_B/I qualified to AEC-Q101 standards?
Yes, SS16HM3_B/I is explicitly AEC-Q101 qualified, as confirmed in the Vishay SS12–SS16 datasheet (Rev. 23-Apr-2020, Doc. #88746). The "HM3" suffix denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. This qualification covers stress tests including HTGB, HTRB, and temperature cycling - essential for automotive power module deployment.
What does the "B/I" suffix indicate in SS16HM3_B/I?
The "B/I" suffix in SS16HM3_B/I identifies the packaging configuration: "B" is the revision code (per Vishay's naming convention), and "I" denotes 13-inch diameter plastic tape and reel with 7500 units per reel. This matches the ordering information table in Document #88746 and confirms factory-standard packaging for automated SMT placement.
What is the forward voltage drop of SS16HM3_B/I at 1.0 A?
The SS16HM3_B/I exhibits a maximum instantaneous forward voltage (VF) of 0.75 V at 1.0 A and TA = 25 °C, per the Electrical Characteristics table in Vishay Document #88746. This value is measured under pulsed conditions (300 μs, 1 % duty cycle) and represents worst-case conduction loss for thermal design calculations.
Does SS16HM3_B/I have a guarded die structure?
Yes, SS16HM3_B/I incorporates a guardring structure, explicitly listed under FEATURES in the Vishay SS12–SS16 datasheet. This design enhances overvoltage protection by controlling electric field distribution at the silicon edge, preventing premature breakdown during transient events such as load dump or inductive kickback in automotive power circuits.
