Product details
Overview
SMA6J17AHR3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a working standoff voltage of 17 V, breakdown voltage range 18.9–20.9 V, and clamping voltage of 26.7 V at 22.5 A peak pulse current. It uses a DO-214AC (SMA) package and is designed for surge protection in DC/DC converters and automotive power systems.
For engineers reviewing the SMA6J17AHR3G datasheet, SMA6J17AHR3G pinout, SMA6J17AHR3G application, or SMA6J17AHR3G equivalent, key selection criteria include its 10/1000 μs waveform peak pulse power rating, ISO 7637-2 compliance, junction temperature range (−55°C to +175°C), and moisture sensitivity level 1 rating.
Technical Context
This unidirectional TVS diode features a glass-passivated silicon junction and fast response time (<1.0 ps), enabling effective suppression of ESD and switching transients. Its single-die configuration and DO-214AC package support automated SMT placement and meet JESD201 Class 2 whisker resistance requirements.
The device operates within a −55°C to +175°C junction temperature range and delivers 600 W peak pulse power under 10/1000 μs waveform conditions. It exhibits 1.0 μA maximum reverse leakage at 17 V and clamps to 26.7 V at 22.5 A, meeting ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements.

Applications
| Automotive Power Distribution | Industrial DC/DC Converters |
|---|---|
Use Scenario: Protection of 12 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rails to clamp surges before they reach PMICs or microcontrollers. Use Value: Clamps to 26.7 V at 22.5 A, keeping downstream 3.3 V/5 V regulators within safe operating area during 600 W pulses. | Use Scenario: Input-side surge suppression in isolated 48 V-to-12 V DC/DC modules used in factory automation. IC Role / Device Role / Timing Role: Primary transient shunt on primary-side bus, coordinated with upstream fuse and downstream LC filtering. Use Value: Withstands repeated 10/1000 μs pulses up to 600 W while maintaining VWM = 17 V to avoid false triggering during normal 18–20 V transients. |
| LED Driver Power Inputs | USB-C PD Adapter Secondary Side |
Use Scenario: Overvoltage protection on constant-current LED string drivers exposed to inductive kickback from MOSFET switches. IC Role / Device Role / Timing Role: Fast-clamping TVS placed across output terminals to protect driver ICs and sense resistors. Use Value: Sub-1 ps response ensures clamping initiates before 20.9 V breakdown is exceeded, preserving LED open-circuit detection accuracy. | Use Scenario: Secondary-side rail protection in compact USB-C PD adapters where space limits use of larger TVS packages. IC Role / Device Role / Timing Role: Standoff-rated TVS on 20 V output rail, selected for tight VBR tolerance (±5.3%) to avoid nuisance conduction. Use Value: DO-214AC footprint enables high-density layout; 17 V VWM provides 3 V margin above nominal 14.5 V PD profile, preventing leakage-induced efficiency loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J17AHE3/61 | Same electrical specs; differs only in tape-and-reel packaging (7,500 pcs vs. 5,000 pcs) and date code marking format | No functional difference; identical performance in all surge tests and thermal profiles | Select SMA6J17AHR3G for standard TSC high-volume reel delivery; choose HE3/61 only if legacy procurement system requires that ordering code |
| SMB6J17A | Same VWM, VBR, VC; uses DO-214AA (SMB) package - 2.5 mm wider body and 0.2 mm taller | Requires PCB pad revision; higher thermal mass offers marginally better steady-state power dissipation (PD = 6 W vs. 4 W) | Choose SMB6J17A only when board layout allows larger footprint and higher continuous power handling is needed |
Compared with SMA6J17AHE3/61 and SMB6J17A, SMA6J17AHR3G provides identical transient suppression performance in the smallest standardized DO-214AC footprint, optimized for high-speed SMT lines and space-constrained automotive modules.
