Product details
Overview
TLP3412SRHA4(TPE from Toshiba Electronic Devices & Storage Corporation is a quad-channel photorelay IC comprising four optically isolated photo-MOSFETs driven by integrated infrared LEDs. It delivers 250 mA max ON-state current, 1.5 Ω max ON-resistance, and 60 V min OFF-state voltage in an S-VSON16T package, operating from −40 °C to +125 °C. It is used in high-speed ATE probe cards and logic/memory tester channel switching.
For engineers reviewing the TLP3412SRHA4(TPE datasheet, TLP3412SRHA4(TPE pinout, TLP3412SRHA4(TPE application, or TLP3412SRHA4(TPE equivalent, key selection criteria include guaranteed 125 °C operation, built-in input resistors eliminating external components, low 20 pF output capacitance for fast switching, and halogen-free S-VSON16T packaging suitable for dense PCB layouts in automated test systems.
Technical Context
The TLP3412SRHA4(TPE implements a monolithic 4-channel photorelay architecture with electrically isolated LED–MOSFET pairs per channel. Each channel features a normally-open (1-Form-A) configuration, integrated input resistor (~1 kΩ typical), and MOSFET output with guaranteed RON ≤ 1.5 Ω at 250 mA and 25 °C.
Its internal structure treats pins 1–8 as a single anode/cathode common input node and pins 9–16 as a dual-drain output node per channel-enabling compact routing while maintaining 300 Vrms isolation and <1 µA OFF-state leakage at 60 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 4 independent, isolated channels in single S-VSON16T package-reduces board area vs. discrete photorelays. |
| ON-state resistance | 1.5 Ω (max) at 250 mA/25 °C-ensures low conduction loss and minimal self-heating in high-current switching. |
| OFF-state voltage | 60 V (min)-supports signal-level switching up to 60 V DC without breakdown in ATE load circuits. |
| Output capacitance | 20 pF (max) at 50 V-enables sub-500 µs turn-off time (tOFF = 50–200 µs) for high-speed test sequencing. |
| Operating temperature | −40 °C to +125 °C-guaranteed performance in thermally demanding ATE environments with localized heating. |
| Isolation voltage | 300 Vrms (min), 60 s-meets safety requirements for galvanic separation between tester control logic and DUT power domains. |
| Input configuration | Built-in series resistor eliminates need for external current-limiting resistor-saves PCB space and simplifies drive circuitry. |
Pinout & Package
S-VSON16T package: 2.0 mm × 6.25 mm × 1.3 mm body, 0.5 mm pitch, 16-pin exposed pad (no thermal pad connection specified), weight 0.04 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,3,5,7 | Anode | Common anode inputs for four internal IR LEDs-requires single current-limited 3–6 V drive source. |
| 2,4,6,8 | Cathode | Common cathode return for LED side-internally shorted; connects to system ground or negative rail. |
| 9,11,13,15 | Drain (Ch1–Ch4) | Individual MOSFET drain terminals-each supports independent load switching up to 250 mA. |
| 10,12,14,16 | Drain (Ch1–Ch4) | Paired drain terminals per channel-dual bonding reduces on-resistance and improves current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four fully isolated photorelay channels in one 2.0 × 6.25 mm package-cuts interconnect count and layout complexity in multi-site ATE fixtures. |
| Built-in input resistor | Integrated ~1 kΩ series resistor per LED-removes need for four external resistors, reducing BOM count and placement footprint. |
| Low-output capacitance | 20 pF max COFF-minimizes capacitive loading on high-speed DUT signals and enables faster channel settling. |
| High-temp reliability | Rated for continuous operation up to +125 °C junction temperature-maintains RON stability and leakage integrity in heated test chambers. |
| Halogen-free construction | Encapsulant meets Toshiba's halogen-free resin standard (Br/Cl ≤ 0.09 wt%, total ≤ 0.15 wt%)-complies with IPC-4101D and RoHS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3412SRA4(TPE | Same S-VSON16T package and 4-channel architecture but lacks built-in input resistors-requires external 1 kΩ resistors per channel. | Higher BOM count and layout area needed; otherwise identical switching specs and temperature range. | Select when design requires adjustable LED current or tighter control over forward voltage drop. |
| PS8501-AL-E3 | 4-channel photorelay in SOIC-16 package; 1.2 Ω max RON, 40 V VOFF, 125 °C rating-but larger 10.3 × 7.6 mm footprint and 35 pF COFF. | Lower density and slower switching due to higher capacitance; suited for less space-constrained industrial controls. | Select only if SOIC-16 compatibility or legacy footprint reuse is mandatory; not recommended for new ATE designs. |
Compared with TLP3412SRA4(TPE, the TLP3412SRHA4(TPE saves four external resistors and reduces layout area by 65% via its S-VSON16T package; versus PS8501-AL-E3, it delivers 43% lower output capacitance and 35% smaller footprint-critical for high-channel-count probe cards where trace length and parasitics directly impact test accuracy.

FAQ
What is the maximum continuous ON-state current rating for the TLP3412SRHA4(TPE?
The TLP3412SRHA4(TPE has a maximum continuous ON-state current rating of 250 mA per channel at 25 °C ambient, derated linearly to zero at 125 °C junction temperature. This rating assumes proper PCB copper area for heat dissipation and accounts for the device's 1.5 Ω max RON and internal thermal limits defined in Toshiba's Absolute Maximum Ratings table.
Does the TLP3412SRHA4(TPE require an external current-limiting resistor on the LED side?
No-the TLP3412SRHA4(TPE integrates a built-in input resistor for each LED channel, eliminating the need for external current-limiting resistors. This feature reduces component count and PCB area, and ensures consistent LED forward current across all four channels when driven with 3–6 V.
What is the isolation voltage specification for the TLP3412SRHA4(TPE, and how is it tested?
The TLP3412SRHA4(TPE provides a minimum isolation voltage of 300 Vrms, tested per IEC 60747-5-5 at 60 Hz for 60 seconds with relative humidity ≤60%. This rating applies between the input (pins 1–8) and output (pins 9–16) sides and confirms safe galvanic separation in ATE signal routing applications.
Can the TLP3412SRHA4(TPE operate reliably at 125 °C ambient temperature?
Yes-the TLP3412SRHA4(TPE is rated for continuous operation from −40 °C to +125 °C ambient temperature. Its guaranteed electrical parameters-including RON, IOFF, and switching times-are specified across this full range, making it suitable for use inside heated ATE enclosures or near high-power DUTs without thermal derating penalties.
What does the "(TPE" suffix indicate in the TLP3412SRHA4(TPE part number?
Within Toshiba's ordering nomenclature, the "(TPE" suffix denotes tape-and-reel packaging per JEDEC standard, with E indicating RoHS-compliant, halogen-free construction. The "TP" portion specifies embossed carrier tape, and "E" confirms compliance with EU Directive 2011/65/EU-verified per Toshiba's environmental documentation for the TLP3412SRHA4(TPE.
