Product details
Overview
1.5SMC160AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 160V working stand-off voltage (VWM), 152–168V breakdown voltage (VBR), 219V maximum clamping voltage (VC) at 7.1A peak impulse current, and 1500W peak pulse power rating - optimized for automotive load-dump and industrial ESD immunity per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the 1.5SMC160AH datasheet, 1.5SMC160AH pinout, 1.5SMC160AH application, or 1.5SMC160AH equivalent, this device is selected for robust overvoltage protection where fast response (<1.0ps), low leakage (<1μA @ 136V), AEC-Q101 qualification, and DO-214AB (SMC) package compatibility with automated SMT assembly are critical design requirements.
Technical Context
This TVS diode operates as a unidirectional clamping device with a single silicon junction, glass passivated for reliability. Its thermal performance includes RθJA = 50°C/W and RθJC = 15°C/W, enabling sustained operation up to TJ = +150°C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Electrical behavior follows ANSI/IEEE C62.35 standards: VBR is measured after 30ms square-wave IT pulse; IPPM uses 10/1000μs waveform per Fig.5; derating applies above TA = 25°C per Fig.2. Clamping occurs within sub-picosecond response time, with VF = 5.0V @ 50A forward surge (per family specification for 1.5SMC100H–200H variants).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin in protected line. |
| VBR min/max | 152 V / 168 V @ IT = 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 219 V @ 7.1 A - Peak clamped voltage during 10/1000μs surge; determines maximum stress on downstream ICs. |
| PPK | 1500 W - Peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Pulse 5a (load dump). |
| IR @ VWM | <1 μA - Ultra-low reverse leakage at rated stand-off; minimizes standby power loss and signal distortion. |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, coordinated with upstream fuses and secondary-side filtering. Use Value: 136V VWM allows headroom above nominal 48V rail while 219V VC ensures downstream DC-DC converters remain within absolute maximum ratings. |
Use Scenario: Adding secondary-side surge immunity to wall adapters powering smart home hubs, set-top boxes, and USB-C PD accessories. IC Role / Device Role / Timing Role: Final-stage protection component placed immediately before the main system board's power entry connector. Use Value: DO-214AB footprint enables compact layout; AEC-Q101 qualification provides extended reliability margin beyond consumer-grade expectations. |
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 | Same VWM (136V), lower PPK (600W), SMB package (smaller footprint, higher RθJA = 65°C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a load dump | Select when space-constrained and surge energy is limited to IEC 61000-4-5 Level 3 (0.5kV/1kV) |
| 1.5KE160A | Same VWM/VBR/VC specs, but axial DO-201 package; higher RθJA (70°C/W); not SMT-compatible | Requires through-hole assembly; incompatible with automated SMT lines and dense PCB layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ160A and 1.5KE160A, the 1.5SMC160AH delivers superior surge energy handling (1500W vs. 600W/600W), SMT-ready DO-214AB packaging, and automotive-qualified reliability - making it the preferred choice for production-grade automotive and industrial power rail protection.

FAQ
What is the clamping voltage of the 1.5SMC160AH under standard test conditions?
The 1.5SMC160AH has a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000μs surge waveform at 7.1 A peak impulse current (IPPM). This value is measured per ANSI/IEEE C62.35 and confirmed in the manufacturer's electrical specifications table. The 1.5SMC160AH maintains this clamping performance across its rated junction temperature range of –55°C to +150°C.
Is the 1.5SMC160AH suitable for bidirectional transient protection?
No - the 1.5SMC160AH is a unidirectional TVS diode, intended for DC line protection with defined anode-cathode polarity. For bidirectional applications, Taiwan Semiconductor specifies the 1.5SMC160CAH variant (with CAH suffix), which provides symmetrical clamping in both directions. Using the 1.5SMC160AH in reverse-biased configurations may result in unintended conduction or failure.
Does the 1.5SMC160AH meet automotive qualification standards?
Yes - the 1.5SMC160AH is explicitly AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM/MM). It also meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transient immunity. These qualifications are documented in Taiwan Semiconductor's official datasheet revision B2207.
What is the maximum steady-state power dissipation for the 1.5SMC160AH?
The 1.5SMC160AH has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25°C. This value decreases with rising ambient temperature per the derating curve in Figure 2 of the datasheet. At 100°C ambient, PD drops to approximately 3.25 W. This rating applies only to continuous DC or low-frequency power dissipation - not to transient pulse conditions covered by the 1500W PPK rating.
How does the 1.5SMC160AH compare to the 1.5SMC160H variant?
The 1.5SMC160AH offers tighter breakdown voltage tolerance (152–168 V) versus the 1.5SMC160H (144–176 V), resulting in more consistent clamping onset. Both share identical VWM (136 V), VC (219 V), PPK (1500 W), and package (DO-214AB). The "A" suffix denotes enhanced VBR uniformity - critical for designs requiring precise overvoltage thresholds across production lots. The 1.5SMC160AH is recommended where parameter consistency impacts system-level surge margin.
