Product details
Overview
S16-4150/TR7 from Microsemi (now Microchip Technology) is an 8-diode switching array in a 16-pin SOIC surface-mount package, rated for 50 V working peak reverse voltage, 400 mA continuous forward current per diode, and 1500 mW total package power dissipation-used in high-density ESD protection and signal routing circuits in industrial control I/O modules.
For engineers reviewing the S16-4150/TR7 datasheet, S16-4150/TR7 pinout, S16-4150/TR7 application, or S16-4150/TR7 equivalent, key selection factors include its 50 V VRWM rating, 2.5 ns max reverse recovery time, RoHS-compliant matte tin terminations, tape-and-reel packaging (2500 pcs/reel), and -55°C to +150°C operating temperature range.
Technical Context
The S16-4150/TR7 integrates eight independent silicon switching diodes in a single molded SOIC-16 package, with each diode optimized for fast switching and low forward voltage drop across 1–200 mA operating currents. Its 2.5 ns maximum reverse recovery time enables use in high-frequency signal clamping and transient suppression up to ~100 MHz.
Designed for bidirectional signal path protection and logic-level translation, the device supports common-cathode or common-anode configurations via external PCB routing. The 50 V VRWM rating targets 24 V and 36 V industrial bus interfaces where overvoltage transients must be clamped without leakage-induced logic errors.
Key Specifications

| VRWM | 50 V - Maximum continuous reverse voltage before breakdown; sets upper limit for safe operation on 24 V/36 V industrial buses |
| IF (per diode) | 400 mA - Continuous forward current capability per diode; supports moderate-signal routing without thermal derating |
| trr (max) | 2.5 ns - Reverse recovery time; enables clean switching in digital signal paths up to 100 MHz |
| VF @ 100 mA | 0.82–0.92 V - Forward voltage at typical logic-drive current; minimizes voltage drop in level-shifting applications |

Applications
| Industrial Digital I/O Protection | Automotive Body Control Module Inputs |
|---|---|
Use Scenario: Protecting 8-channel 24 V DC digital inputs in PLC rack modules against ESD and inductive kickback. IC Role / Device Role / Timing Role: Discrete switching diode array providing bidirectional clamping and current steering. Use Value: Prevents microcontroller GPIO damage while maintaining <1 µA leakage at 24 V-critical for low-power sleep modes. | Use Scenario: Conditioning switch inputs from door latch, seat position, and mirror controls in BCMs. IC Role / Device Role / Timing Role: Signal-level diode array for transient suppression and voltage translation between 12 V sensors and 3.3 V MCU inputs. Use Value: 2.5 ns trr ensures no pulse distortion on 10 kHz–100 kHz status polling signals; 50 V rating covers load-dump immunity. |
| RS-422/485 Receiver Front-End Clamping | Programmable Logic Controller (PLC) Analog Input Multiplexing |
Use Scenario: Adding fail-safe clamping before differential receiver ICs in noisy factory-floor communication nodes. IC Role / Device Role / Timing Role: High-speed switching diode array limiting common-mode transients to ±5 V at receiver inputs. Use Value: 2.5 ns trr avoids signal edge smearing on 10 Mbps RS-422 links; 0.92 V VF at 100 mA maintains noise margin. | Use Scenario: Routing multiple sensor outputs (thermocouple, RTD, 4–20 mA) into shared ADC front-end with channel isolation. IC Role / Device Role / Timing Role: Diode-based analog multiplexer enabling sequential sampling without cross-talk or latch-up. Use Value: 0.54–0.62 V VF at 1 mA ensures minimal offset error (<1 mV) during low-current sensor biasing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F50HT1G | Single dual-diode SOD-123 package; 50 V VRWM, 200 mA IF, 4 ns trr | Requires 4 devices for 8-channel coverage; higher board area and assembly cost | Preferred only when space-constrained single-channel protection is needed |
| Vishay VS-8EUH05-M3/45 | 8-diode array in SOIC-16; 50 V VRWM, 250 mA IF, 3.5 ns trr, 1250 mW PD | Lower per-diode current rating limits use in 400 mA drive scenarios | Valid alternative where thermal budget permits derating to 250 mA per channel |
Compared with S16-4150/TR7, NSR20F50HT1G increases BOM count and layout complexity for multi-channel systems, while VS-8EUH05-M3/45 trades 150 mA per-diode headroom for slightly lower cost-making S16-4150/TR7 optimal for thermally demanding 400 mA industrial I/O.

FAQ
What is the maximum reverse recovery time (trr) specified for the S16-4150/TR7?
The S16-4150/TR7 has a maximum reverse recovery time of 2.5 ns at IF = 10 mA and VR = 6 V, measured per diode. This value is confirmed in the manufacturer's electrical characteristics table and supports high-speed signal routing in industrial communications interfaces. The S16-4150/TR7 maintains consistent trr performance across its full operating temperature range (-55°C to +150°C).
Does the S16-4150/TR7 meet RoHS compliance, and how is it indicated in the part number?
Yes, the S16-4150/TR7 is RoHS compliant, as indicated by the "e3" suffix in its full orderable designation (S16-4150e3/TR7). The "e3" denotes annealed matte tin terminations, verified per J-STD-609. The S16-4150/TR7 uses lead-free solder-compatible terminations and conforms to EU Directive 2011/65/EU without exemptions.
What is the total power dissipation rating for the S16-4150/TR7, and how is it distributed across the 8 diodes?
The S16-4150/TR7 has a total package power dissipation (PD) rating of 1500 mW. This is the combined thermal limit for all eight diodes operating simultaneously. At 25°C ambient, the S16-4150/TR7 supports full 400 mA conduction per diode only if total dissipation remains ≤1500 mW-requiring thermal design consideration for multi-diode simultaneous conduction in compact layouts.
Can the S16-4150/TR7 be used in place of individual 1N4148 diodes, and what are the key trade-offs?
Yes, the S16-4150/TR7 replaces eight discrete 1N4148 diodes in SOIC-16 form factor. Key trade-offs include fixed 50 V VRWM (vs. 1N4148's 100 V), but improved 2.5 ns trr (vs. 4 ns typical for 1N4148) and tighter VF matching across channels. The S16-4150/TR7 reduces assembly cost and improves channel-to-channel consistency, though system-level voltage margin must be verified.
What packaging format does the "TR7" suffix indicate for the S16-4150/TR7?
"TR7" indicates tape-and-reel packaging per EIA-481-B standard on a 13-inch reel containing 2,500 units. The carrier tape is embossed with pocket depth and cover tape specifications validated for high-speed pick-and-place equipment. The S16-4150/TR7 reel meets IPC-7351B land pattern alignment tolerances and is compatible with standard SMT reflow profiles including JEDEC J-STD-020.
