Product details
Overview
SA160H from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, 160V working stand-off voltage (VWM), 178–218V breakdown voltage (VBR), and clamps to ≤257V at 2.0A peak pulse current. It protects automotive power electronics against ESD and load-dump transients.
For engineers reviewing the SA160H datasheet, SA160H pinout, SA160H application, or SA160H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance under standardized surge waveforms, thermal derating behavior, and direct alternatives with documented VWM/VBR/PPK alignment for automotive-grade circuit protection design.
Technical Context
The SA160H operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its specified VBR range (178–218V at 1mA test current), then clamping transient energy to ≤257V at 2.0A IPPM. Its low leakage (<1μA at 160V) ensures minimal standby power loss in high-impedance bias networks.
Designed for automotive environments, it meets AEC-Q101 stress requirements including temperature cycling, humidity bias, and mechanical shock. Its DO-204AC package supports lead-free reflow soldering per J-STD-002 and passes JESD201 Class 2 whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A | Same VWM (160V), lower PPK (400W), SMA package (surface-mount) | Not AEC-Q101 qualified; suited for industrial PCBs where space constraints favor SMT | Select SMAJ160A only if AEC-Q101 compliance is not required and board layout uses SMT footprints. |
| P6SMB160A | Same VWM (160V), same PPK (600W), identical DO-204AC package, AEC-Q101 option available (P6SMB160AH) | Higher clamping voltage (≤274V at 2.2A) and wider VBR tolerance (178–222V) | P6SMB160AH matches SA160H's qualification and form factor but requires verification of clamping margin in high-precision 12V systems. |
Compared with SMAJ160A and P6SMB160A, SA160H offers tighter clamping (≤257V vs. ≥274V), guaranteed AEC-Q101 qualification, and optimized thermal resistance in DO-204AC for through-hole automotive harness connections - making it preferred for safety-critical 12V/24V power rail protection where voltage margin and reliability are non-negotiable.

FAQ
What is the AEC-Q101 qualification status of SA160H?
The SA160H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H" and documentation in the SA Series datasheet Version L2105. This certification covers temperature cycling, high-temperature operating life, and mechanical shock testing required for automotive under-hood and chassis applications. SA160H meets all stress tests defined in AEC-Q101 Rev D, confirming its suitability for deployment in safety-relevant vehicle subsystems.
Does SA160H support bidirectional transient suppression?
No, SA160H is a unidirectional TVS diode, indicated by its single cathode band marking and specification of VBR only for reverse polarity. Bidirectional variants in the SA Series carry "CA" or "C" suffixes (e.g., SA160CA). Using SA160H in bidirectional applications would leave positive-going transients unprotected; for AC or dual-polarity rails, SA160CA or equivalent bidirectional TVS must be selected instead of SA160H.
What is the maximum clamping voltage of SA160H under standard 10/1000μs surge conditions?
The maximum clamping voltage VC of SA160H is 257 V at 2.0 A peak pulse current (IPPM), measured per the 10/1000μs waveform defined in ANSI/IEEE C62.35. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage imposed on protected circuitry during a standardized surge event - critical for verifying headroom against downstream IC absolute maximum ratings.
Can SA160H be used in place of SA160 without redesigning the PCB?
Yes, SA160H shares identical DO-204AC (DO-15) package dimensions, pinout, and soldering specifications with SA160, differing only in AEC-Q101 qualification and minor process enhancements. No PCB layout changes are required when upgrading from SA160 to SA160H; however, SA160H should be specified where automotive qualification is mandated, while SA160 remains appropriate for non-automotive industrial use.
What is the junction temperature limit and thermal derating behavior of SA160H?
SA160H has a maximum junction temperature (TJ) of +175°C and follows the pulse derating curve in Figure 2 of the datasheet: peak pulse power decreases linearly above TA = 25°C, reaching ~50% of 500W at 100°C ambient. At TL = 75°C (lead temperature), steady-state power dissipation is rated at 3W. These thermal characteristics enable reliable operation in engine bay environments when mounted with adequate copper pad area (10 × 10 mm per lead) per datasheet layout guidance.
