Product details
Overview
SMCJ160AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection of DC power rails and signal lines. It features a 160 V stand-off voltage (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMCJ160AHE3_A/I datasheet, SMCJ160AHE3_A/I pinout, SMCJ160AHE3_A/I application, or SMCJ160AHE3_A/I equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ160AHE3_A/I operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to ESD and lightning-induced surges. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance, enabling stable clamping across repetitive transients up to TJ = 150 °C.
Designed per ANSI/IEEE C62.35, it meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance. The device is rated for 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine) and derates linearly above TA = 25 °C per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V–48 V systems. |
| VBR min/max | 178 V / 197 V at IT = 1 mA - Breakdown voltage range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 259 V at 5.8 A (10/1000 μs) - Clamping voltage limits downstream IC stress during surge events; critical for MOSFET gate or MCU I/O protection. |
| PPPM | 1500 W - Peak pulse power handling capacity determines survivability against ISO 7637-2 Pulse 1/2/5a or IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1.0 μA - Ultra-low reverse leakage preserves efficiency in battery-powered or high-impedance sensor circuits. |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and enclosed industrial enclosures without thermal derating penalties. |
| RθJA | 75 °C/W - Thermal resistance measured on standard 0.31" × 0.31" copper pads; informs heatsinking requirements for sustained surge duty cycles. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified. Dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H). Molding compound meets UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection in unidirectional configuration | Connected to protected line (e.g., +12 V rail); clamps positive transients to ground when reverse-biased. |
| Anode | Reference/ground node | Typically tied to system ground plane; establishes reference for clamping action and must maintain low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements including temperature cycling and HTRB. |
| Glass passivated junction | Ensures long-term reliability and stable VBR over 1000+ hours at TJ = 150 °C; eliminates moisture-induced parameter drift. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD > 30 kV), improving protection margin for sensitive analog front-ends. |
| MSL Level 1 (260 °C peak) | Enables single-reflow soldering without moisture sensitivity concerns; eliminates baking requirement prior to assembly. |
| UL 497B recognized (QVGQ2) | Confirms compliance for telecom and industrial signal-line protectors; accepted by safety certifiers for end-equipment listings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AHE3_A/I | Same VWM (160 V) and VC (259 V), but lower PPPM (600 W) and smaller SMB (DO-214AA) package. | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive load dump or telecom primary protection. | Select only when board space is constrained and surge energy does not exceed 600 W. |
| SMCJ160CAHE3_A/I | Bidirectional variant with identical VWM (160 V), VC (259 V), and PPPM (1500 W), but symmetric clamping in both polarities. | Required for AC-coupled or floating signal lines (e.g., RS-485, Ethernet PHY) where negative transients occur. | Choose when protecting bidirectional data lines or ungrounded power rails; not interchangeable with unidirectional SMCJ160AHE3_A/I. |
Compared with SMBJ160AHE3_A/I, the SMCJ160AHE3_A/I delivers 2.5× higher surge energy handling in the same footprint family; versus SMCJ160CAHE3_A/I, it offers optimized cost and lower capacitance for DC rail protection but lacks negative-polarity clamping capability.

FAQ
What is the clamping voltage of the SMCJ160AHE3_A/I under a 10/1000 μs surge?
The SMCJ160AHE3_A/I clamps to a maximum of 259 V when subjected to its rated peak pulse current of 5.8 A with a 10/1000 μs waveform. This value is specified in the Electrical Characteristics table and verified per ANSI/IEEE C62.35 test conditions. The clamping voltage directly determines the maximum stress imposed on downstream components during surge events, making it a critical parameter for circuit protection design using the SMCJ160AHE3_A/I.
Is the SMCJ160AHE3_A/I AEC-Q101 qualified?
Yes, the SMCJ160AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and explicit note in the Mechanical Data section. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for automotive powertrain and body electronics. The SMCJ160AHE3_A/I meets these requirements without derating in ambient temperatures up to +125 °C.
What is the meaning of the "_A/I" suffix in SMCJ160AHE3_A/I?
The "_A/I" suffix in SMCJ160AHE3_A/I indicates packaging and reel configuration: "A" denotes the revision code (per Vishay's ordering nomenclature), and "I" specifies 13-inch diameter plastic tape and reel with 3500 units per reel. This matches the Ordering Information table on page 3 of the datasheet. The base part SMCJ160AHE3 is RoHS-compliant and AEC-Q101 qualified; the "_A/I" suffix adds delivery mode and revision tracking for production traceability of the SMCJ160AHE3_A/I.
Can the SMCJ160AHE3_A/I be used in bidirectional signal protection?
No, the SMCJ160AHE3_A/I is a unidirectional TVS diode and must not be used for bidirectional signal protection. Its cathode band marking and asymmetric IV curve allow clamping only for positive transients relative to ground. For bidirectional applications such as RS-485 or AC-coupled lines, the SMCJ160CAHE3_A/I - the CA-suffixed bidirectional variant - is required. Using the SMCJ160AHE3_A/I in place of a bidirectional device risks failure during negative-going surges.
What is the thermal resistance junction-to-ambient for the SMCJ160AHE3_A/I?
The typical thermal resistance junction-to-ambient (RθJA) for the SMCJ160AHE3_A/I is 75 °C/W, measured on the minimum recommended pad layout (0.31" × 0.31" copper pads per terminal). This value assumes no additional heatsinking and defines the temperature rise above ambient at 6.5 W steady-state dissipation. For pulsed surge conditions, transient thermal impedance curves (Fig. 5) govern short-duration heating, but RθJA remains essential for estimating average power handling in repetitive surge scenarios involving the SMCJ160AHE3_A/I.
