Product details
Overview
SMCJ160AH from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) in DO-214AB (SMC) package, with 160V working stand-off voltage (VWM), 178–197V breakdown voltage (VBR), and 259V maximum clamping voltage (VC) at 6A peak pulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the SMCJ160AH datasheet, SMCJ160AH pinout, SMCJ160AH application, or SMCJ160AH equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJC = 10°C/W), moisture sensitivity level (MSL 1), and bidirectional variant compatibility for robust ESD and surge design validation.
Technical Context
The SMCJ160AH uses a glass-passivated silicon junction to achieve fast response (<1.0 ps from 0 V to VBR min) and low leakage (<1 µA at 160 V). Its unidirectional configuration enables asymmetric clamping on DC power lines while maintaining compliance with ISO 7637-2 test pulses.
Thermal performance is defined by RθJA = 55°C/W and RθJC = 10°C/W, supporting reliable operation up to TJ = +150°C. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for high-reliability PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min / max | 178 V / 197 V - Breakdown occurs within this range at 1 mA test current; defines turn-on threshold tolerance |
| VC @ IPPM | 259 V - Clamped voltage at 6 A peak pulse current; determines worst-case overvoltage seen by protected IC |
| PPK | 1500 W - Peak pulse power handling per 1 ms waveform; supports high-energy automotive load dump events |
| IR @ VWM | <1 µA - Reverse leakage at rated stand-off voltage; ensures minimal quiescent power loss in always-on systems |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments |
| RθJC | 10 °C/W - Junction-to-case thermal resistance; informs heatsink interface design for sustained surge duty cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AH (Bourns) | Same VWM (160 V), lower PPK (600 W), smaller SMB package (DO-214AA), higher VC (274 V @ 4.3 A) | Lower surge energy handling; suitable for space-constrained consumer electronics, not automotive load dump | Select SMCJ160AH when 1500 W pulse power and AEC-Q101 qualification are mandatory |
| 1.5SMC160A (ON Semiconductor) | Identical VWM (160 V), same DO-214AB package, but non-AEC-Q101, higher IR (5 µA @ VWM), VC = 259 V @ 6 A | Lacks automotive qualification; acceptable for industrial/commercial use where AEC-Q101 is not required | Choose SMCJ160AH for automotive-grade traceability, MSL 1, and ISO 7637-2 compliance out-of-box |
Compared with SMBJ160AH and 1.5SMC160A, the SMCJ160AH uniquely combines AEC-Q101 qualification, 1500 W surge rating, and MSL Level 1 in a DO-214AB package-making it the only option qualified for under-hood automotive power rail protection without derating or secondary clamping stages.

FAQ
What is the clamping voltage of SMCJ160AH and how is it measured?
The SMCJ160AH has a maximum clamping voltage (VC) of 259 V, measured at 6 A peak pulse current (IPPM) using the 10/1000 µs standard surge waveform per Fig.5 in the datasheet. This value represents the upper limit of voltage imposed on the protected circuit during a transient event and is critical for ensuring downstream components remain within their absolute maximum ratings.
Is SMCJ160AH suitable for bidirectional transient protection?
No, the SMCJ160AH is a unidirectional TVS diode. For bidirectional protection, the SMCJ160CAH variant must be used-its electrical characteristics apply symmetrically in both directions and it carries the "CAH" suffix per Taiwan Semiconductor's ordering convention.
Does SMCJ160AH meet automotive qualification standards?
Yes, the SMCJ160AH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its qualification includes HTOL, temperature cycling, and unbiased HAST, confirming suitability for under-hood automotive applications.
What is the thermal resistance profile of SMCJ160AH and why does it matter?
The SMCJ160AH has RθJC = 10°C/W and RθJA = 55°C/W. These values define how efficiently heat transfers from the junction to case and ambient, respectively. Low RθJC enables effective heat sinking via PCB copper pours, essential for sustaining repeated surge events without thermal runaway.
How does the marking code "GHP" relate to SMCJ160AH?
"GHP" is the official marking code laser-etched on the SMCJ160AH body per Taiwan Semiconductor's specification. It uniquely identifies the device as the 160 V unidirectional variant in the SMCJ(A)H family and distinguishes it from SMCJ160H (GHN) and bidirectional SMCJ160CAH (GHR).
