Product details
Overview
1.5SMC160AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC160AHE3_A/H datasheet, 1.5SMC160AHE3_A/H pinout, 1.5SMC160AHE3_A/H application, or 1.5SMC160AHE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and SMC (DO-214AB) surface-mount compatibility with automated placement.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (152–168 V), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<1 μA at VWM).
Designed for high-energy transients, it sustains 1500 W peak pulse power (10/1000 μs) with 0.01 % duty cycle, and handles 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal performance is defined by RθJL = 15 °C/W and RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 152–168 V at 1 mA - Voltage range where avalanche conduction initiates reliably; ensures predictable turn-on during surges. |
| VC (Clamping) | 219 V at IPPM = 6.8 A - Maximum voltage seen across protected circuit during 10/1000 μs surge; critical for IC/MOSFET survival. |
| PPPM | 1500 W - Peak surge energy handling capability with standardized 10/1000 μs waveform; validates robustness against lightning/inductive spikes. |
| ID (Leakage) | <1 μA at VWM - Ultra-low reverse leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating enables operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability per stress test requirements, including temperature cycling and HTRB. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0. Polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to protected line's low-side or ground reference; completes clamping loop during transient events. |
| Cathode | Reverse voltage sensing / Avalanche conduction node | Connected to protected line's high-side; voltage referenced to anode determines VWM/VBR/VC thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables protection against severe lightning-induced surges and inductive switching spikes in 12 V/24 V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | Same VWM (136 V), lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a/b or lightning-level threats | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2. |
| 1.5KE160A | Same VWM/VBR/VC specs, axial-lead DO-201 package, higher mounting thermal resistance | Not compatible with automated SMT assembly; requires through-hole rework or manual placement | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ160A-E3/52 and 1.5KE160A, the 1.5SMC160AHE3_A/H delivers superior surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal management), AEC-Q101 qualification, and SMC package compatibility with high-volume SMT lines - making it the preferred choice for automotive and industrial production.

FAQ
What is the clamping voltage of the 1.5SMC160AHE3_A/H under a 10/1000 μs surge?
The 1.5SMC160AHE3_A/H has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 6.8 A with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs rated for ≤24 V or ≤36 V remain within safe operating margins.
Is the 1.5SMC160AHE3_A/H qualified for automotive use?
Yes, the 1.5SMC160AHE3_A/H is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's 1.5SMC series datasheet (Document Number: 88303). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - validating suitability for under-hood and chassis-mounted automotive electronics.
What package type does the 1.5SMC160AHE3_A/H use, and what are its mounting requirements?
The 1.5SMC160AHE3_A/H uses the SMC (DO-214AB) surface-mount package, with dimensions of 7.75 mm × 6.22 mm × 2.62 mm. It requires mounting on minimum 8.0 mm × 8.0 mm copper pads per terminal for rated thermal and power performance, and supports lead-free reflow up to 260 °C (MSL Level 1).
How does the 1.5SMC160AHE3_A/H differ from bidirectional TVS diodes like 1.5SMC160CA?
The 1.5SMC160AHE3_A/H is unidirectional and features a cathode band marking; it conducts only in reverse bias above VBR and blocks forward current like a rectifier. In contrast, 1.5SMC160CA is bidirectional with symmetrical clamping in both polarities and no polarity marking - making the 1.5SMC160AHE3_A/H appropriate for DC supply rail protection, while the CA version suits AC-coupled or differential signal lines.
What is the maximum junction temperature and thermal resistance of the 1.5SMC160AHE3_A/H?
The 1.5SMC160AHE3_A/H has a maximum junction temperature (TJ max.) of +150 °C and typical thermal resistances of RθJA = 75 °C/W (junction-to-ambient, on standard PCB pads) and RθJL = 15 °C/W (junction-to-leads). These values enable reliable operation in high-temperature enclosures and inform heatsinking decisions for sustained surge duty cycles.
