Product details
Overview
DSL70E6327HTSA1 from Infineon Technologies is a silicon TVS diode array for telecom and high-speed line protection designed for PCB-level ESD, EFT, surge, and transient protection in compact electronic systems. part is associated with the DSL70 product family and uses the TO-253-4, TO-253AA package with Tape & Reel (TR) packing for production assembly.
As an Infineon protection component, DSL70E6327HTSA1 combines 50 V working-voltage class, 2.5 pF typical, 5 pF maximum, 2 lines, uni-directional, and compact package integration for connector-side or IC-side protection. For engineers reviewing the DSL70E6327HTSA1 datasheet, DSL70E6327HTSA1 pinout, DSL70E6327HTSA1 application, or DSL70E6327HTSA1 equivalent, this device is commonly evaluated for interface protection, portable electronics, communication ports, industrial modules, and exposed signal lines where transient current must be diverted before it reaches sensitive semiconductor pins.
Technical Context
In a practical PCB layout, DSL70E6327HTSA1 should be placed close to the connector, exposed pad, cable entry point, or protected IC pin so the transient current is shunted before it travels through long board traces. The package and pin configuration determine whether the device is used as a single-line, multi-line, uni-directional, or bi-directional protection element.
The DSL70 family parameters are relevant to signal integrity and protection margin. The working-voltage rating must stay above the normal operating level, while the line capacitance must remain compatible with the protected interface. Clamping voltage, dynamic resistance, surge current, and ESD rating determine how much residual stress reaches the downstream IC during IEC-style tests.
For the DSL70E6327HTSA1 configuration, designers should verify the exact package drawing, orientation, reel or bulk packing, moisture sensitivity, lifecycle status, and any PCN or replacement guidance before production release. For high-speed or RF interfaces, the placement, ground return, and via structure can be as important as the diode rating itself.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Silicon tvs diode array for telecom and high-speed line protection used for board-level protection and transient suppression. |
| Protection Configuration | 2 lines, uni-directional for the DSL70 device family and package option. |
| Working Voltage | 50 V, defining the normal signal or rail voltage range that should not trigger the protection structure. |
| Line Capacitance | 2.5 pF typical, 5 pF maximum, important for RF, USB, display, audio, keypad, touchscreen, or other signal-integrity-sensitive lines. |
| ESD Rating | ±15 kV IEC61000-4-2, supporting system-level ESD robustness when the PCB layout provides a short discharge path. |
| EFT Rating | 80 A 5/50 ns, relevant to cable-connected and industrial environments where fast electrical transients may occur. |
| Surge / Peak Pulse Rating | 27 A 8/20 µs, defining the short-duration pulse-current capability for non-repetitive transient events. |
| Clamping Behavior | 2.6 V + VCC typical at 16 A TLP, which determines the residual voltage presented to the protected IC during a transient. |
| Package | TO-253-4, TO-253AA package, selected for compact placement near connectors or protected IC pins. |
| Packing | Tape & Reel (TR) for SMT assembly and procurement handling. |
| Lifecycle / Design Status | discontinued; confirm the latest product status, PCN history, and substitute strategy before new production use. |
Pinout & Package
The DSL70E6327HTSA1 pinout and package layout should be checked against the Infineon package drawing for the DSL70 product family. The TO-253-4, TO-253AA package is intended for compact PCB placement and should be oriented correctly before footprint, stencil, and inspection rules are finalized.
For ESD and TVS parts, the most effective layout normally uses short traces, a direct return path, and placement close to the transient entry point. For fuse-type BGF devices, the routing should place the fuse in series with the intended protected current path.
| Pin / Function | PCB Design and Circuit Role |
|---|---|
| Protected Line Pin(s) | Connect to the exposed signal, data, RF, supply, or interface line protected by DSL70E6327HTSA1. |
| Ground / Reference Pin | Connect directly to the local ground or reference return where the package configuration provides a dedicated ground pin. |
| Bi-Directional Connection | For bi-directional devices, the diode structure can clamp positive and negative ESD stress around the protected line. |
| Uni-Directional Connection | For uni-directional devices, orientation and return path must match the datasheet schematic and system polarity. |
| Package Footprint | TO-253-4, TO-253AA footprint should be verified against the Infineon package drawing before PCB release. |
| Connector-Side Placement | Place the device close to the connector or transient entry point with short traces and low loop inductance. |

Equivalent & Alternatives
When evaluating DSL70E6327HTSA1 equivalent devices, engineers should compare package footprint, line count, directionality, working voltage, line capacitance, clamping behavior, leakage current, ESD rating, surge rating, lifecycle status, and assembly format.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSL70 | Same-family or functionally comparable Infineon protection device with different package, voltage, capacitance, line count, or lifecycle profile. | Used during BOM continuity review, package migration, lifecycle replacement, or interface-protection redesign. | Do not treat as drop-in without checking pinout, VWM, capacitance, clamping voltage, surge rating, package drawing, and lifecycle status. |
| SR70-02CTG | Same-family or functionally comparable Infineon protection device with different package, voltage, capacitance, line count, or lifecycle profile. | Used during BOM continuity review, package migration, lifecycle replacement, or interface-protection redesign. | Do not treat as drop-in without checking pinout, VWM, capacitance, clamping voltage, surge rating, package drawing, and lifecycle status. |
Compared with another device in the same Infineon protection portfolio, DSL70E6327HTSA1 should be selected only when its DSL70 family parameters match the protected interface and PCB footprint. Substitution should not be based only on package size or voltage name because capacitance, clamping voltage, polarity, and transient-current rating can change system-level behavior.
Quality
