Product details
Overview
5.0SMDJ17AHM6G from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode rated for 5000W peak pulse power at 10/1000μs, with a working standoff voltage of 17V, breakdown voltage range of 18.9–20.9V, and clamping voltage of 27.6V at 181A. It is AEC-Q101 qualified and used in automotive I/O interface and AC/DC power supply protection circuits.
For engineers reviewing the 5.0SMDJ17AHM6G datasheet, 5.0SMDJ17AHM6G pinout, 5.0SMDJ17AHM6G application, or 5.0SMDJ17AHM6G equivalent, key selection criteria include unidirectional clamping performance, DO-214AB package thermal resistance (RθJL = 16°C/W), moisture sensitivity level 1 compliance, and fast response time (<1.0ps).
Technical Context
This TVS diode employs a stacked-die construction in a DO-214AB (SMC) package to achieve high surge robustness while maintaining low clamping ratio (VC/VBR ≈ 1.45). Its photo-glass passivated junction ensures stable leakage (<20µA at VWM) and long-term reliability under repeated transients.
Designed for automotive-grade environments, it operates across –55°C to +175°C junction temperature, supports automated SMT placement, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for molded compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR @ IT=1mA | 18.9–20.9 V - Breakdown voltage range defining turn-on threshold under standardized test current |
| VC @ IPP=181A | 27.6 V - Clamped voltage during 5000W 10/1000μs surge, limiting downstream stress |
| PPPPM | 5000 W - Peak pulse power handling capability per industry-standard waveform |
| RθJL | 16 °C/W - Junction-to-lead thermal resistance enabling effective heat transfer to PCB copper pad |
| αVBR | 0.097 mV/°C - Temperature coefficient of breakdown voltage, critical for thermal stability in wide-temp designs |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, unidirectional configuration with cathode band marking. Matte tin-plated leads, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction or surge clamping | Connected to protected line (e.g., 12V rail); must be routed with low-inductance path to ground reference |
| Cathode | Current exit terminal; marked by visible band on package body | Connected to system ground or low-impedance return path; polarity reversal prevents clamping function |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use including engine control, infotainment, and ADAS subsystems |
| Fast response time <1.0ps | Enables suppression of ESD and lightning-induced transients before sensitive ICs are damaged |
| Moisture sensitivity level 1 | Eliminates need for baking prior to reflow, reducing manufacturing complexity and cost |
| Stacked die architecture | Delivers 5000W surge rating in compact DO-214AB footprint without derating at elevated ambient temperatures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | Lower peak power (600W), same DO-214AA package, VC = 27.6V @ 21.2A | Not suitable for automotive load dump; limited to low-energy ESD and inductive switching | Select only when surge energy is ≤600W and AEC-Q101 is not required |
| 5.0SMDJ17A | Same electrical specs but non-AEC-Q101 grade; identical DO-214AB package and marking code 5PEU | Lacks automotive qualification; acceptable for industrial/commercial power supplies where qualification is not mandated | Choose for cost-sensitive non-automotive designs requiring identical clamping and thermal performance |
Compared with SMBJ17A and 5.0SMDJ17A, the 5.0SMDJ17AHM6G delivers certified automotive reliability, full 5000W surge margin, and moisture-insensitive assembly-making it the sole option for Tier-1 automotive front-end protection where both energy handling and qualification are mandatory.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ17AHM6G under a 10/1000μs surge?
The 5.0SMDJ17AHM6G has a maximum clamping voltage (VC) of 27.6 V when subjected to its rated peak pulse current of 181 A, corresponding to a 5000 W surge per the 10/1000 μs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 5.0SMDJ17AHM6G suitable for bidirectional signal line protection?
No, the 5.0SMDJ17AHM6G is a unidirectional TVS diode, designed only for DC power rail or single-polarity signal line protection. For bidirectional applications such as AC lines or differential buses, a dedicated bidirectional part like 5.0SMDJ17CAHM6G-or a back-to-back unidirectional pair-must be used instead of the 5.0SMDJ17AHM6G.
What does the "M6G" suffix indicate in 5.0SMDJ17AHM6G?
The "M6G" suffix in 5.0SMDJ17AHM6G denotes tape-and-reel packaging: M6 = 3,000 units per reel, G = green molding compound per IEC 61249-2-21 halogen-free specification. It does not affect electrical parameters but confirms RoHS and halogen-free compliance per the datasheet revision A2102.
How does the 5.0SMDJ17AHM6G perform at elevated junction temperatures?
The 5.0SMDJ17AHM6G maintains full functionality from –55°C to +175°C junction temperature. Its breakdown voltage exhibits a positive temperature coefficient of +0.097 mV/°C, and pulse power derating follows Fig.1 in the datasheet-e.g., at TJ = 125°C, peak power drops to ~70% of 5000W, requiring appropriate thermal design using its RθJL = 16°C/W rating.
Can the 5.0SMDJ17AHM6G replace older 5.0SMDJ17A parts in existing designs?
Yes-the 5.0SMDJ17AHM6G is a direct drop-in replacement for 5.0SMDJ17A in terms of pinout, package (DO-214AB), and electrical specifications; the "H" denotes AEC-Q101 qualification and "M6G" specifies packaging. No PCB layout changes are needed, but designers gain certified automotive reliability and enhanced moisture resistance (MSL Level 1).
