Product details
Overview
TGL41-75A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 71.3 V to 78.8 V breakdown voltage (VBR), 64.1 V standoff voltage (VWM), and 400 W peak pulse power (10/1000 µs). It clamps transients to ≤103 V at 3.9 A peak pulse current and operates from –55 °C to +150 °C junction temperature - deployed for protecting MOSFETs and sensor signal lines in industrial power supplies.
For engineers reviewing the TGL41-75A-E3/97 datasheet, TGL41-75A-E3/97 pinout, TGL41-75A-E3/97 application, or TGL41-75A-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 103 V clamping voltage at rated IPPM, thermal derating above 25 °C, and RoHS-compliant matte tin terminations per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges on DC power rails and low-speed signal paths. Its unidirectional configuration allows integration into positive-rail protection schemes without reverse-bias leakage concerns beyond 5 µA at VWM.
The device is rated for 400 W peak pulse power (10/1000 µs waveform, 0.01% duty cycle) up to 91 V, then derates to 200 W above that threshold per Fig. 2; it supports 40 A non-repetitive forward surge current (8.3 ms half-sine) and maintains stable clamping performance across –55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V - ensures reliable conduction onset above normal 64.1 V system operating voltage while avoiding false triggering |
| VWM | 64.1 V - maximum continuous reverse voltage before significant leakage; sets upper limit for protected circuit DC rail |
| VC @ IPPM | 103 V - clamped voltage during 3.9 A transient, defining worst-case overvoltage seen by downstream ICs |
| PPPM | 400 W (≤91 V), 200 W (>91 V) - defines energy-handling capacity for standard lightning/surge waveforms |
| IFSM | 40 A - withstands single 8.3 ms half-sine surge without bond-wire failure, critical for motor drive snubbing |
| Junction Temp Range | –55 °C to +150 °C - enables use in under-hood automotive modules and industrial enclosures without thermal derating penalties |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with solderable ends, compatible with high-speed pick-and-place and reflow profiles |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with two solderable axial terminals. The blue band denotes the cathode (positive terminal during TVS conduction); anode is unmarked end. No internal leads or pads - terminals are integral to molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | TVS anode connection point during clamping | Connected to protected line (e.g., +12 V rail); conducts when line voltage exceeds VBR relative to ground |
| Anode (unmarked end) | Reference/ground return path | Must be tied to low-impedance system ground to complete clamping loop; determines polarity and directionality |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated planar junction | Enables <1 ns response time and stable VBR tolerance (±5%) across temperature and life cycle |
| 400 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) on 12 V/24 V systems without degradation |
| MSL Level 1 (J-STD-020) | Zero floor-life limitation; supports standard SMT reflow without baking or dry-pack requirements |
| Matte tin plating (JESD 201 Class 1A) | Eliminates tin whisker risk in long-life industrial deployments; ensures solder joint reliability >10 years |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed power supplies and telecom chassis during fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA75A-E3/73 | Same VBR (71.3–78.8 V), but SMA package (DO-214AC); 400 W rating, 103 V clamping, but higher thermal resistance (RθJA ≈ 110 °C/W vs. GL41's ~75 °C/W) | Suitable for PCBs with surface-mount footprint constraints; less optimal for high-ambient-temp environments due to lower power derating | Select when board space is limited and thermal management includes copper pour or forced air |
| SMBJ75A | Identical electrical specs (VBR, VC, PPPM) but SMB package (DO-214AA); slightly larger footprint, better thermal dissipation than SMA, same MSL level | Better suited for industrial designs requiring higher long-term reliability under sustained 75 °C ambient | Prefer for fixed-mount, non-automated assembly or where GL41's MELF handling poses placement challenges |
Compared with P4SMA75A-E3/73 and SMBJ75A, the TGL41-75A-E3/97 offers superior thermal performance in compact MELF form factor and automated placement compatibility, making it optimal for high-volume consumer and telecom power supply designs where footprint and reflow yield are critical.

FAQ
What is the clamping voltage of the TGL41-75A-E3/97 at its rated peak pulse current?
The TGL41-75A-E3/97 clamps to a maximum of 103 V when subjected to its specified peak pulse current of 3.9 A (10/1000 µs waveform). This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-75A-E3/97 achieves this clamping performance while maintaining tight VBR tolerance and low dynamic impedance.
Is the TGL41-75A-E3/97 suitable for new designs despite Vishay's "Not For New Designs" notice?
The "Not For New Designs" designation applies to the entire TGL41 family and reflects Vishay's strategic shift toward newer platforms like the P4SMA series; however, the TGL41-75A-E3/97 remains fully manufactured, stocked, and supported with no announced discontinuance. Aetrix Electronics guarantees full supply continuity and technical documentation access for the TGL41-75A-E3/97 through 2028, making it viable for legacy refresh and cost-sensitive production.
Does the TGL41-75A-E3/97 have bidirectional capability?
No, the TGL41-75A-E3/97 is strictly unidirectional, as confirmed in the Vishay datasheet section "FEATURES" and "PRIMARY CHARACTERISTICS". It features a blue band marking the cathode and is intended for protection of positive-rail circuits only. Bidirectional variants are not offered in the TGL41 series; alternative families such as SMAJ or SMCJ would be required for AC or dual-polarity applications.
What is the meaning of the "/97" suffix in TGL41-75A-E3/97?
Per Vishay's ordering information table, the "/97" suffix indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This contrasts with "/96", which denotes 7-inch reels of 1500 units. Both share identical electrical and mechanical specifications; the suffix solely identifies reel size and quantity - critical for SMT line feed optimization and inventory planning for the TGL41-75A-E3/97.
How does the GL41 (DO-213AB) package of the TGL41-75A-E3/97 compare thermally to SMA or SMB packages?
The GL41 (DO-213AB) package provides lower junction-to-ambient thermal resistance (~75 °C/W) compared to SMA (DO-214AC, ~110 °C/W) and slightly higher than SMB (DO-214AA, ~65 °C/W), due to its cylindrical geometry and direct lead-to-body thermal path. This makes the TGL41-75A-E3/97 well-suited for moderate-power surge suppression where MELF placement automation is prioritized. Thermal performance of the TGL41-75A-E3/97 is validated per JEDEC JESD51-2 standards.
