Product details
Overview
TGL41-27-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) MELF package, designed for clamping voltage transients on signal and power lines. It features 25.7 V to 28.4 V breakdown voltage (VBR), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor signal lines in industrial control systems.
For engineers reviewing the TGL41-27-E3/96 datasheet, TGL41-27-E3/96 pinout, TGL41-27-E3/96 application, or TGL41-27-E3/96 equivalent, key selection criteria include unidirectional polarity, glass-passivated junction, MSL Level 1 moisture sensitivity, 0.099 %/°C temperature coefficient of VBR, and compatibility with automated placement in high-reliability consumer and telecom protection circuits.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, activating when reverse voltage exceeds VWM (23.1 V) and entering avalanche breakdown between 25.7 V and 28.4 V. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching transients and ESD events.
The device uses a glass-passivated silicon junction housed in a plastic MELF (DO-213AB) package with matte tin-plated terminals, rated for -55 °C to +150 °C operating junction temperature and compliant with JESD201 Class 1A whisker testing. It delivers 400 W peak pulse power only up to 91 V; above that, rating drops to 200 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - defines precise avalanche onset range under 1.0 mA test current; critical for accurate overvoltage threshold setting |
| VWM | 23.1 V - maximum continuous reverse working voltage before leakage exceeds 5 μA; sets safe operating margin below breakdown |
| VC @ IPPM | 37.5 V at 10.7 A - clamped voltage during 10/1000 μs transient; determines protected circuit's maximum stress level |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform at 0.01 % duty cycle; defines transient energy absorption capacity |
| IFSM | 40 A - peak forward surge current rating for 8.3 ms half-sine wave; supports robustness against repetitive inrush or fault currents |
| TJ max | 150 °C - maximum junction temperature; constrains thermal design and derating requirements in high-power density layouts |
| Package | DO-213AB (GL41) - standardized MELF outline with 0.105" diameter, enabling high-density automated placement and reflow compatibility |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is marked by a blue band indicating the cathode (positive terminal under normal TVS operation). No internal leads or pads - terminals are formed by metallized 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; establishes reference for VWM and VBR thresholds |
| Cathode (blue band) | Transient voltage sensing and clamping node | Connected to protected line; conducts avalanche current when voltage exceeds VBR, limiting VC to 37.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity only | Enables precise clamping on DC-biased lines without forward conduction interference; eliminates need for series blocking diodes |
| Glass-passivated chip junction | Ensures stable VBR and low leakage (<5 μA at VWM) across temperature and lifetime; improves long-term reliability in harsh environments |
| MSL Level 1 per J-STD-020 | Allows unlimited floor life and standard reflow profiles without baking; reduces manufacturing complexity and cost |
| 400 W peak pulse power (≤91 V) | Provides sufficient energy absorption for common IEC 61000-4-5 surge events (e.g., 2 kV line-to-ground) without degradation |
| 0.099 %/°C VBR tempco | Minimizes drift of clamping threshold over industrial temperature range (-55 °C to +150 °C); maintains protection margin stability |
Applications
| Industrial Motor Control | Automotive Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA (SMB) package; 24 V VWM, 38.9 V VC @ 10.3 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB area increase and different pick-and-place nozzle | Select when higher surge margin is needed and board space allows SMB outline; not drop-in due to package mismatch |
| 1.5SMC27A | DO-214AB (SMC) package; 27 V VWM, 43.0 V VC @ 9.3 A; 1500 W PPPM | Three times higher clamping voltage and significantly larger thermal mass; suited for primary-side AC line protection | Choose for mains-input stage protection where 43 V clamping is acceptable; incompatible with MELF-reflow profiles and layout |
Compared with SMBJ24A and 1.5SMC27A, the TGL41-27-E3/96 offers superior board-area efficiency and MSL Level 1 compatibility for high-volume automated assembly, while delivering optimized clamping performance (37.5 V) for low-voltage DC signal lines - making it preferred for space-constrained industrial and telecom edge devices.
