Product details
Overview
VS-16RIA100M from Vishay Semiconductors is a medium-power phase-control thyristor (SCR) in stud-mount TO-48 (TO-208AA) package, rated for 16 A average on-state current, 100 V repetitive peak off-state voltage (VDRM/VRRM), and 1.75 V maximum on-state voltage at 50 A and 25 °C. It operates from −65 °C to +125 °C junction temperature and delivers 340 A non-repetitive surge current at 50 Hz with 110 μs typical turn-off time, suited for industrial AC power control circuits.
For engineers reviewing the VS-16RIA100M datasheet, VS-16RIA100M pinout, VS-16RIA100M application, or VS-16RIA100M equivalent, key selection criteria include dI/dt capability (200 A/μs at ≤600 V), dV/dt rating (300 V/μs at 67% VDRM), gate trigger current (60 mA at 25 °C), thermal resistance (0.86 K/W junction-to-case), and stud-mount mechanical interface compatibility with M6 × 1 metric threads.
Technical Context
This single SCR device uses glass-passivated junction technology for high reliability under thermal stress and supports phase-angle control in line-synchronized AC systems. Its triggering behavior is defined by gate threshold voltage (2.0 V at 25 °C) and latching current (200 mA), with turn-on governed by fast gate pulse response (0.9 μs typical tgt) and controlled commutation via external circuit design.
Blocking performance is characterized by critical dV/dt immunity (300 V/μs at 67% rated VDRM) and reverse recovery time (4 μs at TJ max), while conduction losses are modeled using dual-slope on-state resistance (rt1 = 17.9 mΩ, rt2 = 13.6 mΩ) and low VT(TO) values (0.97–1.24 V), enabling predictable thermal management in medium-power switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 16 A average on-state current - defines continuous DC-equivalent load handling at 85 °C case temperature |
| VDRM/VRRM | 100 V - maximum repetitive peak off-state voltage; determines minimum AC line isolation margin |
| VTM | 1.75 V at 50 A, 25 °C - sets worst-case forward conduction loss and associated heat generation |
| IGT | 60 mA at 25 °C - maximum gate current required to reliably trigger; informs driver stage sizing |
| tq | 110 μs typical turn-off time - constrains minimum off-period in phase-controlled AC waveforms |
| RthJC | 0.86 K/W - junction-to-case thermal resistance; enables heatsink sizing for steady-state operation |
| dI/dt | 200 A/μs (≤600 V) - rate-of-rise immunity during turn-on; prevents false triggering from transient currents |
| dV/dt | 300 V/μs at 67% VDRM - critical off-state dv/dt immunity; avoids spurious turn-on in noisy AC environments |
Pinout & Package
VS-16RIA100M uses a stud-mount TO-48 (TO-208AA) package with M6 × 1 metric thread base, featuring three terminals: Anode (A), Cathode (C), and Gate (G). The anode serves as the main high-current output path, the cathode forms the return path and thermal interface, and the gate controls conduction initiation. Mechanical mounting torque is specified at 0.23–0.32 kgf·m (lubricated/non-lubricated).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current output terminal | Carries full load current during conduction; electrically and thermally coupled to metal stud base |
| Cathode (C) | Main current return terminal | Completes SCR conduction path; provides primary thermal path to heatsink via mounting surface |
| Gate (G) | Trigger control input | Receives low-energy pulse to initiate conduction; requires precise voltage/current compliance per IGT/VGT specs |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Enables stable operation up to +125 °C junction temperature with minimal parameter drift over life |
| High dI/dt capability | 200 A/μs rating ensures robust turn-on without false triggering under high di/dt transients |
| Low RthJC | 0.86 K/W junction-to-case resistance allows efficient heat transfer to heatsink in compact layouts |
| Metric thread option | M6 × 1 stud base simplifies mechanical integration into industrial equipment with standardized mounting |
| Standardized TO-48 footprint | Ensures interchangeability with legacy stud-mount thyristors in existing PCB/heatsink designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar thyristor-based phase control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST162S100 | Same 16 A IT(AV), 100 V VDRM, but TO-220AB package with isolated tab; higher RthJC (1.5 K/W) | Requires PCB-mount layout and insulated heatsink; unsuitable for stud-mounted chassis integration | Select when board-level assembly is preferred and thermal budget allows higher junction rise |
| IXYS MCR16-10 | 16 A IT(AV), 100 V VDRM, TO-220AC package; lower dI/dt (100 A/μs) and no metric thread option | Limited to PCB mounting; less robust against fast current transients in high-noise environments | Choose for cost-sensitive consumer-grade controls where dV/dt immunity and mechanical ruggedness are secondary |
Compared with ST162S100 and IXYS MCR16-10, VS-16RIA100M offers superior thermal performance (0.86 K/W vs. ≥1.5 K/W), higher dI/dt immunity (200 A/μs), and direct M6 stud-mount integration-making it optimal for industrial equipment demanding mechanical durability, thermal efficiency, and noise resilience.

FAQ
What is the maximum junction temperature rating for VS-16RIA100M?
The VS-16RIA100M has a maximum operating junction temperature of +125 °C and a storage temperature range from −65 °C to +125 °C. This wide thermal envelope supports deployment in demanding industrial environments such as motor drives and welding equipment where ambient temperatures exceed 85 °C. Thermal design must account for RthJC = 0.86 K/W and RthCS = 0.35 K/W to maintain VS-16RIA100M within safe operating limits under full-load conditions.
Does VS-16RIA100M support both 50 Hz and 60 Hz AC line frequencies?
Yes, VS-16RIA100M is fully rated for both 50 Hz and 60 Hz operation. Its non-repetitive surge current is specified as 340 A at 50 Hz and 360 A at 60 Hz, and its I²t rating adjusts accordingly (574 A²s at 50 Hz, 524 A²s at 60 Hz). The device's 110 μs typical turn-off time (tq) and 4 μs reverse recovery time (trr) ensure reliable commutation across both standard utility frequencies without risk of shoot-through or failure to commutate.
What gate drive requirements must be met to reliably trigger VS-16RIA100M?
To reliably trigger VS-16RIA100M, the gate must receive a pulse delivering at least 60 mA peak current (IGT) and 2.0 V gate-to-cathode voltage (VGT) at 25 °C. Gate pulse duration should exceed 6 μs with rise time ≤0.1 μs, and source impedance should be ≤20 Ω for full-rated dI/dt operation. At 125 °C, IGT drops to 35 mA, so drive circuits must accommodate this derating to ensure consistent turn-on across the full temperature range of VS-16RIA100M.
Is VS-16RIA100M compatible with standard heatsink mounting practices?
Yes, VS-16RIA100M features an M6 × 1 metric threaded stud base conforming to TO-48 (TO-208AA) mechanical specifications. It is designed for direct bolt-down to flat, smooth, greased heatsinks with recommended mounting torque of 0.23–0.32 kgf·m (lubricated/non-lubricated). Its 0.35 K/W case-to-sink thermal resistance (RthCS) assumes proper surface finish and thermal compound application-ensuring VS-16RIA100M achieves optimal thermal performance in industrial power modules and panel-mounted controls.
How does the glass passivation in VS-16RIA100M improve long-term reliability?
The glass passivation layer on VS-16RIA100M protects the silicon junction from moisture, contaminants, and thermal stress-induced degradation. Documented in Vishay's reliability qualification, this process enables exceptional parameter stability at +125 °C junction temperature and extends operational lifetime in humid or chemically aggressive environments. Unlike polymer-passivated devices, VS-16RIA100M maintains consistent VDRM, IGT, and tq performance over >10⁵ switching cycles-critical for VS-16RIA100M deployments in unattended industrial systems.
