Product details
Overview
TGL41-24A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 22.8 V minimum breakdown voltage, 20.5 V standoff voltage, and 33.2 V clamping voltage at 12.0 A peak pulse current. It delivers 400 W peak pulse power (10/1000 μs), operates from −55 °C to +150 °C, and protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-24A-E3/96 datasheet, TGL41-24A-E3/96 pinout, TGL41-24A-E3/96 application, or TGL41-24A-E3/96 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, 20.5 V working voltage margin, and 33.2 V clamping performance under 12 A surge conditions.
Technical Context
The TGL41-24A-E3/96 uses a glass-passivated planar junction for stable avalanche breakdown and low incremental surge resistance. Its unidirectional configuration provides forward conduction path during reverse transient suppression, with cathode marked by blue band and VF = 3.5 V at 25 A.
Designed per ANSI/IEEE C62.35, it supports 0.01% duty cycle repetitive surges and meets J-STD-020 MSL Level 1 (250 °C lead-free reflow). Thermal derating begins above TA = 25 °C, with 1.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - defines guaranteed avalanche initiation range at 1.0 mA test current |
| VWM | 20.5 V - maximum continuous reverse voltage before leakage exceeds 5 μA |
| VC @ IPPM | 33.2 V at 12.0 A - clamped voltage during 10/1000 μs transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling capability under standard waveform, critical for surge immunity |
| IFSM | 40 A - 8.3 ms half-sine surge current rating, supporting high-energy inductive load switching |
| TJ Range | −55 °C to +150 °C - enables operation in harsh industrial and automotive under-hood environments |
| Package | GL41 (DO-213AB) - MELF-style surface-mount package optimized for automated placement and thermal reliability |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA24A-E3/96 | Same VWM (20.5 V) and VC (33.2 V), but lower PPPM = 400 W in SMA package; higher thermal resistance due to smaller footprint | Suitable for PCBs with space constraints where DO-213AB mounting is impractical; less effective in high-ambient thermal environments | Select when board real estate is limited and peak ambient temperature remains <70 °C |
| SMAJ24A | Identical electrical specs but in SMA package; no E3 RoHS suffix or JESD 201 Class 1A whisker rating | Acceptable for commercial-grade designs without strict whisker or lead-free compliance requirements | Choose only if qualification for automotive or long-life industrial use is not required |
Compared with TGL41-24A-E3/96, P4SMA24A-E3/96 offers identical clamping but reduced thermal mass in SMA form, while SMAJ24A lacks formal whisker and RoHS certifications-making TGL41-24A-E3/96 the preferred choice for high-reliability, long-lifecycle deployments.

FAQ
What is the polarity configuration of the TGL41-24A-E3/96?
The TGL41-24A-E3/96 is a unidirectional TVS diode, with cathode identified by a blue band. During normal operation, the cathode is positive relative to the anode; it conducts avalanche current from cathode to anode when reverse voltage exceeds VBR. This configuration ensures precise clamping on positive-going transients while blocking steady reverse bias up to VWM = 20.5 V.
Does the TGL41-24A-E3/96 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-24A-E3/96 carries the E3 suffix, confirming full RoHS compliance and qualification for lead-free reflow per J-STD-020 MSL Level 1 (peak temperature 250 °C). Its matte tin-plated leads satisfy JESD 22-B102 solderability and JESD 201 Class 1A whisker resistance standards, making it suitable for high-reliability industrial and automotive production.
What is the maximum clamping voltage of the TGL41-24A-E3/96 under surge conditions?
The TGL41-24A-E3/96 has a maximum clamping voltage VC of 33.2 V at IPPM = 12.0 A using the 10/1000 μs waveform. This value is measured under standardized non-repetitive pulse conditions and defines the upper voltage limit imposed on protected circuitry during transient events-critical for ensuring downstream components like MOSFETs and microcontrollers remain within safe operating voltage ranges.
Can the TGL41-24A-E3/96 be used in bidirectional signal line protection?
No, the TGL41-24A-E3/96 is unidirectional only and must not be used on AC-coupled or bidirectional data lines. Its design provides clamping only for positive transients relative to the anode; reverse polarity transients will forward-bias the device and cause uncontrolled conduction. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ24CA or equivalent must be selected instead of the TGL41-24A-E3/96.
What is the thermal derating behavior of the TGL41-24A-E3/96 above 25 °C ambient?
The TGL41-24A-E3/96 exhibits linear thermal derating above TA = 25 °C, with peak pulse power capability decreasing per Figure 2 in the datasheet. At 75 °C ambient, its PPPM remains at 400 W for short pulses, but steady-state power dissipation drops to 1.0 W only when mounted on an infinite heatsink at TL = 75 °C. For sustained operation, designers must consult the power derating curve (Figure 5) to ensure junction temperature stays below 150 °C.
