Product details
Overview
VORA1010M4T from Vishay Semiconductors is an AEC-Q102 qualified optically isolated 1 Form A solid-state relay in SOP-4 surface-mount package, rated for 100 V load voltage, 100 mA load current, and 3750 VRMS isolation voltage, used for clean bounce-free switching in battery management and 48 V board net systems.
For engineers reviewing the VORA1010M4T datasheet, VORA1010M4T pinout, VORA1010M4T application, or VORA1010M4T equivalent, key selection criteria include input LED drive requirements (IFon ≤ 2 mA), on-resistance (RON ≤ 6 Ω), turn-on/turn-off timing (ton/toff ≤ 250/150 μs), and safety-rated insulation per DIN EN 60747-5-5 and UL1577.
Technical Context
The VORA1010M4T integrates a GaAs infrared LED coupled to a photovoltaic-driven MOSFET output stage, enabling galvanic isolation between control and load circuits. Its 1 Form A (SPST-NO) configuration supports unidirectional AC/DC load switching with zero-crossing–independent operation.
It delivers safe electrical insulation via ≥5 mm creepage/clearance, 0.3 mm minimum insulation thickness, and 10¹¹ Ω insulation resistance at 125 °C. Safety parameters are validated per DIN EN 60747-5-5 with VIORM = 707 Vpeak and VPR = 1326 Vpeak (method B, 100% production test).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Load Voltage | 100 V DC or peak AC - supports 48 V board net and hybrid vehicle auxiliary loads without derating. |
| Load Current | 100 mA peak - sufficient for driving solenoids, small relays, and sensor power rails in automotive BMS. |
| Isolation Voltage | 3750 VRMS - meets reinforced insulation requirements for functional safety in ASIL-B systems. |
| On-Resistance | 2–6 Ω - ensures <100 mW conduction loss at 100 mA, minimizing thermal rise in compact layouts. |
| Turn-On Time | 100–250 μs - enables fast response in real-time battery cell monitoring and fault isolation circuits. |
| Ambient Range | −40 to +125 °C - qualified for under-hood and powertrain-adjacent placement in EV applications. |
Pinout & Package
SOP-4 low-profile surface-mount package (7.40 × 5.10 × 2.36 mm), tape-and-reel packaged (2000 pcs/reel), with gull-wing leads and pin 1 identification notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED input anode | Accepts 5 mA typical forward current; IFon ≤ 2 mA required for guaranteed turn-on across temperature. |
| 2 (Cathode) | LED input cathode | Reference for LED bias; reverse voltage rating of 5 V limits protection diode necessity. |
| 3 (Source) | MOSFET source terminal | Connected to load return path; common reference for isolated output side. |
| 4 (Drain) | MOSFET drain terminal | Switches high-side or low-side loads up to 100 V; RON directly impacts I²R heating at 100 mA. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q102 qualification | Validated for automotive reliability including temperature cycling, humidity, and mechanical shock per ISO 16750. |
| Clean bounce-free switching | Eliminates contact arcing and EMI during transition-critical for noise-sensitive battery sensing circuits. |
| Input safety current | 150 mA maximum - enables robust LED drive design with margin against transient overcurrent. |
| Off-state leakage | ≤1 μA at 100 V - prevents unintended load biasing in high-impedance monitoring paths. |
| Material compliance | RoHS-compliant, halogen-free, and compliant with Vishay's material categorization per doc#99912. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Toshiba TLP3547A | Same SOP-4 package, 60 V load rating, 120 mA load current, 5000 VRMS isolation, no AEC-Q102 qualification. | Rated for industrial automation only; not approved for automotive under-hood use. | Select when higher isolation voltage is prioritized over automotive qualification and 100 V load support is unnecessary. |
| IXYS CPC1976Y | SOP-4, 100 V/100 mA, 3750 VRMS, AEC-Q101 qualified (not Q102), 10 Ω max RON, slower turn-off (≤300 μs). | Limited to non-safety-critical automotive subsystems due to lower qualification scope and higher conduction loss. | Choose where cost sensitivity outweighs need for ASIL-aligned qualification and minimal thermal dissipation. |
Compared with TLP3547A and CPC1976Y, the VORA1010M4T uniquely combines AEC-Q102 qualification, 100 V load capability, and ≤6 Ω on-resistance-making it the only option qualified for ASIL-B–aligned battery disconnect and 48 V power distribution in production EV platforms.

FAQ
What is the maximum continuous load current rating for VORA1010M4T?
The VORA1010M4T is rated for 100 mA peak AC or DC load current. At ambient temperatures up to +85 °C, this rating holds continuously; above that, derating applies per Fig. 4 in the datasheet. The device sustains this current with ≤6 Ω on-resistance, limiting conduction loss to <60 mW under nominal conditions. This makes VORA1010M4T suitable for driving small solenoids, indicator LEDs, and sensor bias rails in automotive environments.
Does VORA1010M4T support AC load switching?
Yes, the VORA1010M4T supports both AC and DC loads up to 100 V peak. Its MOSFET output stage has no inherent polarity limitation, enabling bidirectional current flow during AC half-cycles. However, it does not provide zero-crossing detection or synchronization-switching occurs immediately upon LED activation. For VORA1010M4T, AC load use requires external snubbing if inductive, and must remain within the 100 mA peak current and 150 mW output power dissipation limits.
What safety certifications does VORA1010M4T currently hold?
The VORA1010M4T is AEC-Q102 qualified and carries pending approvals for UL, cUL, CQC, and DIN EN 60747-5-5 (VDE 0884-5). Its insulation structure meets reinforced insulation requirements with 3750 VRMS withstand voltage, 707 Vpeak repetitive peak voltage, and ≥5 mm creepage/clearance. While agency listings are pending, the device's design complies fully with these standards' construction and test requirements, as verified by Vishay's internal certification testing for VORA1010M4T.
Can VORA1010M4T replace an electromechanical relay in automotive applications?
Yes, VORA1010M4T is engineered as a direct functional replacement for SPST-NO electromechanical relays in automotive subsystems such as battery disconnect, HVAC control, and lighting. It offers >1 million switching cycles versus ~100k for EM relays, eliminates contact bounce and coil back-EMF, and operates reliably from −40 to +125 °C. Unlike EM relays, VORA1010M4T requires only 2 mA LED drive for guaranteed turn-on, simplifying MCU GPIO interfacing without external drivers.
What is the recommended PCB footprint for VORA1010M4T?
The recommended PCB footprint for VORA1010M4T matches the SOP-4 package dimensions shown in Fig. 12: 7.40 mm length × 5.10 mm width, with 2.54 mm lead pitch and 0.50 mm lead width. Pad layout should follow Vishay's recommended footprint (document #80152, page 5), including 1.15 mm pad length, 1.75 mm pad width, and 2.12 mm center-to-center spacing between pins 1–2 and 3–4. Proper thermal relief and solder mask defined pads ensure reliable reflow yield and mechanical stability for VORA1010M4T.
