Product details
Overview
TGL41-33-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 31.4–34.7 V breakdown voltage, and 45.7 V clamping voltage at 8.8 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-33-E3/97 datasheet, TGL41-33-E3/97 pinout, TGL41-33-E3/97 application, or TGL41-33-E3/97 equivalent, key selection criteria include unidirectional polarity, 28.2 V stand-off voltage, low 0.101 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated terminals suitable for automated placement.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ps) and low incremental surge resistance to clamp transient overvoltages before downstream components are damaged. Its DO-213AB package enables high thermal dissipation in compact surface-mount layouts while meeting MSL Level 1 reflow requirements (peak 250 °C).
The device operates exclusively in unidirectional mode with cathode marked by a blue band; it delivers stable clamping performance across -55 °C to +150 °C junction temperature range and supports repetitive 0.01 % duty cycle pulses. Stand-off voltage (28.2 V) ensures reliable blocking during normal operation without leakage-induced power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 31.4–34.7 V at 1.0 mA - defines minimum voltage at which clamping initiates, ensuring protection starts before system overvoltage thresholds are exceeded |
| Stand-off Voltage VWM | 28.2 V - maximum continuous reverse working voltage; must exceed circuit's normal operating voltage to prevent false triggering |
| Clamping Voltage VC | 45.7 V at 8.8 A IPPM - peak voltage seen by protected circuit during worst-case transient; determines stress on downstream MOSFET/IC |
| Peak Pulse Power PPPM | 400 W (10/1000 μs) - energy-handling capability for standard lightning/surge waveforms; derates above 25 °C per Fig. 2 |
| Reverse Leakage ID | 5.0 μA at VWM - minimal standby current draw; critical for low-power sensor and battery-backed systems |
| Operating Temperature | -55 °C to +150 °C - wide junction range supports under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| VBR Tempco | 0.101 %/°C - low drift ensures consistent clamping threshold across temperature; avoids false trips or inadequate protection at extremes |
Pinout & Package
DO-213AB (GL41) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal during TVS conduction). Dimensions: D1 = 2.41–2.67 mm, length = 6.0 mm max, mounting pad layout 4.7–5.2 mm center-to-center.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to lower-potential side of protected line | Not used in normal TVS operation; only conducts during fault conditions when voltage exceeds VBR |
| Cathode | Current exit point during clamping; marked by blue band; connected to higher-potential side (e.g., VCC, signal line) | Defines polarity - device only clamps positive transients relative to anode; incorrect orientation disables protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability and stable electrical parameters under thermal cycling and humidity exposure |
| 400 W peak pulse power (10/1000 μs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without degradation in typical 24 V industrial bus designs |
| MSL Level 1 reflow compatibility | Supports lead-free reflow up to 250 °C peak without delamination or parameter shift - eliminates pre-baking requirement |
| Low 0.101 %/°C VBR tempco | Maintains ±3 % clamping window from -40 °C to +125 °C ambient, enabling robust protection in unheated enclosures |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability - certified for commercial-grade production |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of gate drivers and microcontrollers against back-EMF spikes from relay and solenoid coil de-energization in PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between gate driver output and MOSFET gate to clamp negative-going transients below -0.7 V and positive overshoots above 45.7 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | DO-214AA (SMB) package; 33 V VWM, 53.3 V VC at 7.5 A; 600 W PPPM | Higher clamping voltage (+7.6 V) and larger footprint; better suited for higher-energy surges where board space allows | Select SMBJ33A when 600 W rating is required and PCB layout accommodates SMB outline; not drop-in due to different package and thermal profile |
| P6KE33A | DO-15 axial package; 33 V VWM, 53.3 V VC at 7.5 A; 600 W PPPM | Through-hole mounting only; longer lead inductance increases clamping delay; unsuitable for high-frequency transients | Choose P6KE33A for legacy through-hole designs or cost-sensitive non-automated assembly; avoid in new SMT designs requiring <100 ns response |
Compared with SMBJ33A and P6KE33A, the TGL41-33-E3/97 offers lower clamping voltage (45.7 V vs. 53.3 V), smaller MELF footprint for dense layouts, and superior thermal cycling reliability - making it optimal for modern SMT industrial and automotive control modules where space and response speed are critical.

FAQ
What is the clamping voltage of the TGL41-33-E3/97 and how is it measured?
The TGL41-33-E3/97 has a maximum clamping voltage (VC) of 45.7 V, measured at 8.8 A peak pulse current using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the highest voltage imposed on the protected circuit during transient suppression and is guaranteed across the full operating temperature range. The TGL41-33-E3/97 achieves this low VC via optimized junction design and low incremental surge resistance.
Is the TGL41-33-E3/97 suitable for bidirectional transient protection?
No, the TGL41-33-E3/97 is unidirectional only, with cathode marked by a blue band and specified for clamping positive transients relative to the anode. It does not suppress negative transients beyond its forward voltage (~3.5 V at 25 A). For bidirectional protection, a separate device such as the TGL41-33CA or dual-series configuration would be required. The TGL41-33-E3/97 datasheet explicitly states "available in uni-directional polarity only."
What is the meaning of the "E3/97" suffix in TGL41-33-E3/97?
The "E3" suffix indicates RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/97" specifies packaging in 13-inch diameter plastic tape and reel with 5000 units per reel. This format ensures compatibility with high-speed pick-and-place machines and satisfies environmental compliance requirements for commercial-grade production. The TGL41-33-E3/97 is not compatible with /96 (7-inch reel, 1500 units) in automated feeders without reel change.
How does the TGL41-33-E3/97 perform under elevated temperature conditions?
The TGL41-33-E3/97 exhibits a VBR temperature coefficient of +0.101 %/°C, causing breakdown voltage to increase linearly with junction temperature. Its peak pulse power rating derates above 25 °C per Figure 2 in the datasheet, dropping to ~200 W at 91 °C ambient. The TGL41-33-E3/97 maintains full functionality up to +150 °C junction temperature but requires thermal design consideration in high-power-density layouts.
Can the TGL41-33-E3/97 replace older P6KE33A devices in existing designs?
The TGL41-33-E3/97 is not a direct replacement for P6KE33A due to fundamental differences: DO-213AB (MELF) vs. DO-15 (axial) package, surface-mount vs. through-hole mounting, and distinct thermal and inductance characteristics. While both share similar VWM (28.2 V vs. 28.2 V) and VC (45.7 V vs. 53.3 V), the TGL41-33-E3/97 requires PCB redesign. Migration to TGL41-33-E3/97 is recommended only for new SMT designs prioritizing miniaturization and automated assembly.
