Product details
Overview
STRVS241X02E from STMicroelectronics is a unidirectional repetitive voltage suppressor (TVS) diode designed for clamping transient overvoltages in power semiconductor protection circuits. It delivers 241 V clamping voltage at 2 A peak pulse current, features 0.5 µA max leakage at 25 °C and 171–210 V breakdown range, and is housed in DO-15 package with 175 °C max junction temperature - deployed in flyback MOSFET gate drive protection.
For engineers reviewing the STRVS241X02E datasheet, STRVS241X02E pinout, STRVS241X02E application, or STRVS241X02E equivalent, this page provides verified clamping behavior across temperature (25/85/125 °C), thermal resistance (Rth(j-a) = 105 °C/W), dynamic resistance (3.5 Ω), and IEC 61000-4-2/4-5 compliance data to support surge robustness validation in high-repetition-rate switching circuits.
Technical Context
The STRVS241X02E operates as a unidirectional avalanche diode with defined clamping characteristics at 25 °C, 85 °C, and 125 °C - enabling stable overvoltage suppression in thermally varying environments like auxiliary power supplies. Its breakdown voltage shifts predictably with temperature (αT = 10.8 × 10⁻⁴ /°C), and it sustains 2 A peak pulse current without degradation under repetitive surge conditions.
Designed for high-surge-frequency applications, it exhibits low dynamic resistance (3.5 Ω) and low leakage (0.5 µA @ 25 °C), ensuring minimal standby power loss and precise voltage limiting during fast transients. The DO-15 package supports lead-free soldering per MIL-STD-750 method 2026 and meets UL94 V0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clamping Voltage (VCL) | 241 V @ IPP = 2 A (125 °C typical); defines maximum voltage seen by protected device during surge |
| Breakdown Voltage (VBR) | 171–210 V range @ IR = 1 mA; ensures reliable turn-on before system damage threshold |
| Leakage Current (IRM) | 0.5 µA max @ VRM and 25 °C; minimizes quiescent power loss in always-on protection paths |
| Junction Temperature Range | –55 to +175 °C (DO-15); enables operation in high-ambient industrial power stages |
| Thermal Resistance (Rth(j-a)) | 105 °C/W on recommended PCB pad layout; determines steady-state temperature rise under sustained leakage |
| Dynamic Resistance (Rd) | 3.5 Ω; governs voltage overshoot during fast-rising transients (dV/dt < 100 V/ns) |
| ESD Robustness | ±15 kV air / ±8 kV contact (IEC 61000-4-2 Level 4); qualifies for harsh industrial interface zones |
Pinout & Package
STRVS241X02E is packaged in DO-15 - axial-leaded, epoxy-encapsulated case with cathode band marking. Leads are solder-plated and compliant with MIL-STD-750 method 2026. Polarity is unidirectional: cathode band denotes the terminal connected to circuit ground or lower potential side during clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Protected circuit node (e.g., MOSFET drain or gate) | Connected to point requiring overvoltage clamping; conducts during reverse-biased surge |
| Cathode (banded end) | Reference/return path (typically ground or rail) | Serves as clamping reference; must be low-inductance connection to minimize VCL overshoot |
Key Features
| Feature | Design Value |
|---|---|
| Triple-temperature clamping spec | Clamping voltage guaranteed at 25 °C, 85 °C, and 125 °C - eliminates derating guesswork in thermally stressed designs |
| High-temperature junction rating | 175 °C max operating junction temperature (DO-15) - supports continuous operation near power semiconductors |
| Low dynamic resistance | 3.5 Ω enables tighter clamping window vs. standard TVS diodes (>5 Ω), reducing stress on downstream FETs |
| Repetitive surge qualification | Validated for repeated 2 A pulses - suitable for flyback snubber and gate-drive protection where surges occur >100×/second |
| UL94 V0 epoxy & RoHS-compliant | Meets flame-retardant and environmental requirements for industrial equipment certification (EN 60950-1, EN 62368-1) |
Applications
| Motor Drive Inverter Protection | Flyback Converter MOSFET Protection |
|---|---|
|
Use Scenario: Repetitive voltage spikes induced by IGBT/MOSFET switching in 3-phase motor drives. IC Role / Device Role / Timing Role: Unidirectional TVS placed across DC bus or phase-leg switches to clamp commutation spikes. Use Value: Prevents cumulative gate oxide stress and avalanche failure in power devices operating at 10–20 kHz PWM frequencies. |

IC Role / Device Role / Timing Role: Clamps reflected output voltage spikes at MOSFET drain during off-time. Use Value: Enables use of lower-RDS(on) MOSFETs by limiting VDS peak to 241 V, improving efficiency without sacrificing reliability. |
| Industrial Auxiliary Power Supply | DC-DC Converter Input Stage Protection |
|
Use Scenario: Transient coupling from main AC input into low-power auxiliary rails powering control ICs. IC Role / Device Role / Timing Role: Standoff-rated TVS on +12 V or +15 V auxiliary output to absorb line-induced surges. Use Value: Maintains stable bias supply under repeated 1 kV/µs transients, preventing microcontroller brownouts or latch-up. |
Use Scenario: Load-dump or ISO 7637-2 pulse 5a surges entering isolated DC-DC converter inputs in factory automation systems. IC Role / Device Role / Timing Role: Primary-side clamping element absorbing 10–100 ms overvoltage events before regulation stage. Use Value: Eliminates need for bulk capacitance oversizing by limiting input voltage excursion to 241 V, reducing board area and cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STRVS225X02E | Lower clamping voltage (225 V), higher dynamic resistance (5.5 Ω), same DO-15 package | Better suited for 200–220 V nominal bus systems where tighter clamping margin is required | Select when protecting 200 V-class MOSFETs with lower VDSS rating and higher surge repetition tolerance |
| STRVS248X02C | Same clamping (248 V), SMC package (surface-mount), Rth(j-a) = 150 °C/W, higher thermal mass | Preferred for automated assembly and space-constrained layouts; less effective in high-ambient thermal zones | Choose for reflow-compatible designs needing identical clamping performance but no axial leads or manual insertion |
Compared with STRVS225X02E and STRVS248X02C, STRVS241X02E offers optimal balance of clamping precision (241 V), thermal capability (105 °C/W on PCB), and through-hole manufacturability - making it ideal for field-serviceable industrial power modules where replacement and thermal management are both critical.

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in power management, analog, MEMS, and microcontrollers for industrial, automotive, and consumer markets.
The STRVSX series was developed specifically for repetitive overvoltage suppression in power electronics - targeting applications where traditional TVS diodes fail due to thermal runaway under frequent surge conditions.
FAQ
What is the maximum peak pulse current the STRVS241X02E can handle?
The STRVS241X02E is rated for 2 A peak pulse current (IPP) per IEC 61000-4-5 waveform (8/20 µs). Its clamping voltage is specified at this current level (241 V @ 125 °C), and it is validated for repetitive application - meaning it sustains multiple 2 A pulses without parameter shift or degradation, unlike single-pulse-rated TVS devices.
How does the DO-15 package affect thermal performance compared to SMC or SMB?
The DO-15 package has Rth(j-a) = 105 °C/W on recommended PCB layout - lower than SMB (185 °C/W) but higher than SMC (150 °C/W). Its axial leads allow direct heatsinking via chassis mounting or copper pour extension, enabling better steady-state thermal management in high-ambient environments than surface-mount alternatives.
Can STRVS241X02E replace standard TVS diodes like SMAJ24A in flyback designs?
No - STRVS241X02E is not a drop-in replacement for SMAJ24A. It has higher standoff (≈171 V vs. 24 V), different clamping (241 V vs. 38.9 V), and is optimized for repetitive surges rather than single-event ESD. Using it in place of a 24 V TVS would leave circuits unprotected; it targets 200+ V bus protection where standard TVS diodes cannot survive repeated stress.
Is the STRVS241X02E suitable for automotive applications?
No - ST explicitly states STRVSX devices are not designed or authorized for automotive, safety-critical, or aerospace applications. They lack AEC-Q200 qualification and are excluded from use in vehicles per ST's product disclaimer. For automotive-grade TVS, consult ST's Automotive TVS portfolio (e.g., SMAJxxAY series).
