Product details
Overview
TGL41-47A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 44.7 V minimum breakdown voltage, 40.2 V standoff voltage, and 6.2 A peak pulse current under 10/1000 μs waveform - designed for clamping inductive switching transients on signal lines of industrial sensor units.
For engineers reviewing the TGL41-47A-E3/96 datasheet, TGL41-47A-E3/96 pinout, TGL41-47A-E3/96 application, or TGL41-47A-E3/96 equivalent, key selection criteria include unidirectional polarity, 64.8 V maximum clamping voltage at rated surge, 1.0 W steady-state power dissipation, and MSL Level 1 moisture sensitivity for reflow compatibility.
Technical Context
This TVS diode employs a glass-passivated planar junction for stable breakdown characteristics and low incremental surge resistance. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining high impedance below VWM.
The device operates across -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 with 250 °C peak reflow profile. Clamping performance is specified per ANSI/IEEE C62.35 with 10/1000 μs waveform and 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 44.7 V / 49.4 V - defines reliable avalanche initiation range under 1.0 mA test current |
| VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA |
| VC @ IPPM | 64.8 V - clamped voltage at 6.2 A peak pulse ensures downstream IC protection margin |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave, critical for inductive load switching |
| TJ max | +150 °C - maximum junction temperature supports operation in enclosed industrial enclosures |
| Polarity | Unidirectional - cathode marked by blue band; enables DC-biased line protection without forward conduction loss |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode terminal. No internal leads - terminals are the two axial ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-biased clamping | Connected to ground or lower-potential rail; carries surge current during transient |
| Cathode (blue band end) | Clamping output node | Connected to protected line; voltage clamps to ≤64.8 V when transient exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA47A-E3/96 | Same VWM (40.2 V), identical DO-214AC (SMA) package; 1.5x higher junction capacitance (120 pF vs. ~50 pF) | Less suitable for high-speed data lines due to higher CJ; better thermal mass for sustained surge duty | Select when board space allows SMA footprint and surge repetition rate exceeds 0.01% |
| SMAJ47A | DO-214AC package; 400 W rating but 67.2 V clamping voltage (vs. 64.8 V); ±5% VBR tolerance same | Higher clamping increases risk of downstream IC latch-up in 3.3 V logic interfaces | Prefer only where legacy SMA layout exists and clamping margin >2.4 V is acceptable |
Compared with P4SMA47A-E3/96 and SMAJ47A, TGL41-47A-E3/96 offers lower clamping voltage and MELF form factor optimized for high-density automated assembly - critical for compact sensor modules where thermal cycling reliability and placement accuracy are prioritized.

FAQ
What is the clamping voltage of the TGL41-47A-E3/96 under rated surge conditions?
The TGL41-47A-E3/96 has a maximum clamping voltage (VC) of 64.8 V when subjected to its rated 6.2 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured at TA = 25 °C and guarantees protection margin for 48 V nominal systems. The TGL41-47A-E3/96 maintains this clamping performance across its full operating temperature range.
Is the TGL41-47A-E3/96 suitable for automated SMT assembly?
Yes, the TGL41-47A-E3/96 uses a GL41 (DO-213AB) plastic MELF package explicitly designed for automated placement. Its matte tin-plated ends meet J-STD-002 solderability standards, and MSL Level 1 rating permits standard reflow profiles without pre-baking. The TGL41-47A-E3/96 is supplied in 7" tape-and-reel (E3/96) format compatible with high-speed pick-and-place machines.
Does the TGL41-47A-E3/96 have bidirectional capability?
No, the TGL41-47A-E3/96 is unidirectional only, with polarity indicated by a blue band marking the cathode. It conducts in forward bias like a standard diode but clamps transients only in reverse direction. For AC-coupled or bipolar signal lines, a separate bidirectional variant or back-to-back configuration would be required - the TGL41-47A-E3/96 does not support symmetrical clamping.
What is the maximum steady-state power dissipation for the TGL41-47A-E3/96?
The TGL41-47A-E3/96 has a maximum steady-state power dissipation (PD) of 1.0 W at TL = 75 °C on an infinite heatsink. This rating applies to continuous DC or low-frequency reverse leakage conditions, not transient events. Derating is required above 75 °C ambient, per the power derating curve in the official Vishay datasheet for TGL41-47A-E3/96.
How does the TGL41-47A-E3/96 compare to older DO-41 TVS diodes in terms of surge reliability?
The TGL41-47A-E3/96 improves upon legacy DO-41 TVS diodes with glass-passivated planar junction technology, delivering tighter VBR tolerance (±5%), lower leakage (<5 μA), and superior surge life endurance. Its DO-213AB package eliminates leadframe variability, enhancing consistency in automated assembly - a key reliability advantage over DO-41 parts in high-volume industrial production of the TGL41-47A-E3/96.
