Product details
Overview
TGL41-27A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) 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 TGL41-27A-E3/96 datasheet, TGL41-27A-E3/96 pinout, TGL41-27A-E3/96 application, or TGL41-27A-E3/96 equivalent, this page delivers verified electrical parameters, mechanical package details, real-world protection use cases, and validated alternative parts for legacy design continuity and supply chain planning.
Technical Context
This TVS diode employs a glass-passivated planar junction in a plastic MELF case, enabling fast response time (<1 ns) and low incremental surge resistance. Its unidirectional polarity - marked by a blue cathode band - ensures forward conduction only during reverse overvoltage events, with clamping action triggered above 23.1 V.
The device operates across -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (peak reflow ≤250 °C). It delivers 400 W peak pulse power at 25 °C, derating linearly above TA = 25 °C per Figure 2, and supports repetitive transient suppression at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - defines reliable turn-on threshold under 1.0 mA test current; ensures clamping initiates before downstream IC damage. |
| VWM | 23.1 V - maximum continuous reverse working voltage; must exceed normal circuit operating voltage to prevent leakage or false triggering. |
| VC @ IPPM | 37.5 V at 10.7 A - clamped voltage during 10/1000 µs surge; determines worst-case stress on protected load. |
| PPPM | 400 W - peak pulse power handling with 10/1000 µs waveform; enables robust protection against inductive switch-off spikes. |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine); validates survivability during high-energy fault conditions. |
| Junction Temp Range | -55 °C to +150 °C - supports operation in harsh industrial and automotive under-hood environments without thermal shutdown. |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with matte tin-plated leads; compatible with automated placement and reflow soldering (J-STD-002). |
Pinout & Package
GL41 (DO-213AB) is a two-terminal axial MELF package with no internal pins; terminals are symmetrically formed ends of the cylindrical body. The blue band denotes the cathode (positive terminal during clamping), while the unmarked end is the anode. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Clamping output node | Connected to protected line; sinks surge current to ground when reverse voltage exceeds VWM. |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping current path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V industrial buses. |
| Glass-passivated planar junction | Delivers stable VBR tolerance (±5%) and low leakage (<5 µA at VWM) over lifetime and temperature. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; simplifies SMT manufacturing flow. |
| Unidirectional polarity only | Optimized for DC-biased lines (e.g., 24 V PLC inputs, sensor VCC rails) where reverse conduction is not required. |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial enclosures and safety-critical equipment. |
Applications
| Industrial PLC I/O Protection | Automotive Sensor Signal Lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA27A-E3/96 | Same VWM (23.1 V), identical VC (37.5 V), but in DO-214AC (SMA) package - 2.5 mm × 4.5 mm surface-mount vs. MELF cylinder. | Requires PCB layout change; better suited for high-density layouts where MELF placement is impractical. | Select when board space constraints preclude MELF footprint or when leveraging existing SMA reflow profiles. |
| SMAJ27A-E3/52 | Lower PPPM (400 W same), but higher VC (45.7 V at 8.8 A) and wider VBR tolerance (5.5% vs. 5.0%); DO-214AC package. | Less precise clamping margin; acceptable where protected IC has higher absolute maximum ratings. | Choose for cost-sensitive consumer designs where 45.7 V clamp remains within downstream IC safe operating area. |
Compared with TGL41-27A-E3/96, P4SMA27A-E3/96 offers identical electrical performance in a more compact, widely supported SMD package, while SMAJ27A-E3/52 trades tighter clamping for broader availability and lower unit cost - both require validation of thermal dissipation and layout compatibility.

FAQ
What is the exact breakdown voltage range for TGL41-27A-E3/96?
The TGL41-27A-E3/96 has a guaranteed breakdown voltage (VBR) range of 25.7 V to 28.4 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This 5% tolerance ensures consistent clamping initiation across production lots and temperature extremes from -55 °C to +150 °C, making TGL41-27A-E3/96 suitable for precision overvoltage protection in regulated 24 V systems.
Is TGL41-27A-E3/96 RoHS compliant and lead-free?
Yes, TGL41-27A-E3/96 carries the "E3" suffix, indicating full RoHS compliance (per Directive 2011/65/EU) and lead-free construction. Its matte tin-plated leads meet JESD 201 Class 1A whisker resistance requirements, and the molding compound complies with UL 94 V-0 flammability standards - all confirmed in Vishay document 88403 revision 14-Nov-2023.
Can TGL41-27A-E3/96 be used in bidirectional configurations?
No, TGL41-27A-E3/96 is unidirectional only, as explicitly stated in its datasheet features and polarity marking (blue cathode band). It conducts only during reverse-biased overvoltage events and cannot suppress positive-going transients on AC or bipolar signal lines. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ26CA must be selected instead of TGL41-27A-E3/96.
What is the maximum clamping voltage of TGL41-27A-E3/96 under surge conditions?
The maximum clamping voltage (VC) of TGL41-27A-E3/96 is 37.5 V at 10.7 A peak pulse current with a 10/1000 µs waveform, per Table 1 in Vishay document 88403. This value represents the worst-case voltage seen by downstream components during standardized surge testing and is critical for verifying that protected ICs remain within their absolute maximum ratings.
Why is TGL41-27A-E3/96 marked as "Not For New Designs"?
Vishay designates TGL41-27A-E3/96 as "Not For New Designs" due to strategic portfolio rationalization and migration toward newer platforms like the P4SMA series. While TGL41-27A-E3/96 remains fully manufactured and supported for existing designs, new projects should evaluate P4SMA27A-E3/96 or SMAJ27A-E3/52 - both offering identical electrical specs in more modern, widely adopted packages, ensuring longer-term supply assurance for TGL41-27A-E3/96 users.
